INTRODUCTION The RCM3305 and RCM3315 RabbitCore modules feature a compact module that incorporates the latest revision of the powerful Rabbit® 3000 microprocessor, flash memory, mass storage (serial flash), static RAM, and digital I/O ports. The RCM3305 and RCM3315 feature an integrated 10/100Base-T Ethernet port, and provide for LAN and Internet-enabled systems to be built as easily as serial-communication systems. In addition to the features already mentioned above, the RCM3305 and RCM3315 have two clocks (main oscillator and real-time clock), reset circuitry, and the circuitry necessary for management of battery backup of the Rabbit 3000’s internal real-time clock and the static RAM. Two 34-pin headers bring out the Rabbit 3000 I/O bus lines, parallel ports, and serial ports. The RCM3305’s and the RCM3315’s mass-storage capabilities make them suited to running the optional Dynamic C FAT file system module and the featured remote application update where data are stored and handled using the same directory file structure commonly used on PCs. The RCM3305 or RCM3315 receives +3.3 V power from the customer-supplied motherboard on which it is mounted. The RCM3305 and RCM3315 can interface with all kinds of CMOS-compatible digital devices through the motherboard. The Development Kit has what you need to design your own microprocessor-based system: a complete Dynamic C software development system and a Prototyping Board that allows you to evaluate the RCM3305 or RCM3315, and to prototype circuits that interface to the RCM3305 or RCM3315 module. User’s Manual 1 1.1 RCM3305/RCM3315 Features • Small size: 1.85" x 2.73" x 0.86" (47 mm x 69 mm x 22 mm) • Microprocessor: Rabbit 3000 running at 44.2 MHz • 49 parallel 5 V tolerant I/O lines: 43 configurable for I/O, 3 fixed inputs, 3 fixed outputs • Three additional digital inputs, two additional digital outputs • External reset • Alternate I/O bus can be configured for 8 data lines and 6 address lines (shared with parallel I/O lines), plus I/O read/write • Ten 8-bit timers (six cascadable) and one 10-bit timer with two match registers • 512K flash memory, 512K program execution SRAM, 512K data SRAM • Serial-flash mass-storage memory options, which are required to run the optional Dynamic C FAT file system module and the featured remote application update. • Real-time clock • Watchdog supervisor • Provision for customer-supplied backup battery via connections on header J4 • 10-bit free-running PWM counter and four pulse-width registers • Two-channel Input Capture (shared with parallel I/O ports) can be used to time input signals from various port pins • Two-channel Quadrature Decoder accepts inputs from external incremental encoder modules • Five or six 3.3 V CMOS-compatible serial ports with a maximum asynchronous baud rate of 5.525 Mbps. Three ports are configurable as a clocked serial port (SPI), and two ports are configurable as SDLC/HDLC serial ports (shared with parallel I/O ports). • Supports 1.15 Mbps IrDA transceiver The RCM3900/RCM3910 and RCM3365/RCM3375 RabbitCore modules are similar to the RCM3305/RCM3315 and RCM3309/RCM3319, but they use fixed NAND or removable media for their mass-storage memories instead of the fixed serial flash options of the RCM3305/RCM3315 and the RCM3309/RCM3319. 2 RabbitCore RCM3305/RCM3315 Table 1 below summarizes the main features of the RCM3305 and the RCM3315 modules. Table 1. RCM3305/RCM3315 Features Feature Microprocessor SRAM RCM3305 Rabbit 3000 running at 44.2 MHz 512K program (fast SRAM) + 512K data Flash Memory (program) Flash Memory (mass data storage) Serial Ports RCM3315 512K 8 Mbytes (serial flash) 4 Mbytes (serial flash) 5 shared high-speed, 3.3 V CMOS-compatible ports: all 5 are configurable as asynchronous serial ports; 3 are configurable as a clocked serial port (SPI) and 1 is configurable as an HDLC serial port; option for second HDLC serial port at the expense of 2 clocked serial ports (SPI) The RCM3305 and RCM3315 are programmed over a standard PC serial port through a programming cable supplied with the Development Kit, and can also be programed through a USB port with an RS-232/USB converter, or directly over an Ethernet link using the featured remote application update or the Dynamic C download manager with or without a RabbitLink. Appendix A provides detailed specifications for the RCM3305 and the RCM3315. User’s Manual 3 1.2 Comparing the RCM3309/RCM3319 and RCM3305/RCM3315 We can no longer obtain certain components for the RCM3305/RCM3315 RabbitCore modules that support the originally specified -40°C to +70°C temperature range. Instead of changing the design of the RCM3305/RCM3315 RabbitCore modules to handle available components specified for the original temperature range, we decided to develop a new product line — the RCM3309/RCM3319 — based on the RCM3900 RabbitCore modules that were released for the same reason. The RCM3309/RCM3319 modules are similar in form, dimensions, and function to the RCM3305/RCM3315 modules. We strongly recommend that existing RCM3305/3315 customers and designers of new systems consider using the new RCM3309/RCM3319 RabbitCore modules. This section compares the two lines of RabbitCore modules. • Temperature Specifications — RCM3305/RCM3315 RabbitCore modules manufactured after May, 2008, are specified to operate at 0°C to +70°C. The RCM3309/ RCM3319, rated for -40°C to +85°C, are offered to customers requiring a larger temperature range after May, 2008. • Maximum Current — The RCM3305/RCM3315 draws 390 mA vs. the 325 mA required by the RCM3309/RCM3319. • LEDs — The SPEED and user (USR/BSY)LED locations have been swapped between the RCM3305/RCM3315 and the RCM3309/RCM3319, the LNK/ACT LEDs have been combined to one LED on the RCM3309/RCM3319, and the RCM3309/RCM3319 has an FDX/COL LED instead of the SF LED on the RCM3305/RCM3315. The SF LED on the RCM3305/RCM3315 blinks when data are being written to or read from the serial flash. The FDX/COL LED on the RCM3309/RCM3319 indicates whether the Ethernet connection is in full-duplex mode (steady on) or that a half-duplex connection is experiencing collisions (blinks). NOTE: The change in LED indicators means that there is no indication on the RCM3309/RCM3319 when data are being written to or read from the serial flash. • Ethernet chip. A different Ethernet controller chip is used on the RCM3309/RCM3319. The Ethernet chip is able to detect automatically whether a crossover cable or a straightthrough cable is being used in a particular setup, and will configure the signals on the Ethernet jack interface. • Dynamic C — As long as no low-level FAT file system calls were used in your application developed for the RCM3305/RCM3315, you may run that application on the RCM3309/RCM3319 after you recompile it using Dynamic C v. 9.60. 4 RabbitCore RCM3305/RCM3315 1.3 Advantages of the RCM3305 and RCM3315 • Fast time to market using a fully engineered, “ready-to-run/ready-to-program” microprocessor core. • Competitive pricing when compared with the alternative of purchasing and assembling individual components. • Easy C-language program development and debugging • Program download utility (Rabbit Field Utility) and cloning board options for rapid production loading of programs. • Generous memory size allows large programs with tens of thousands of lines of code, and substantial data storage. • Integrated Ethernet port for network connectivity, with royalty-free TCP/IP software. • Ideal for network-enabling security and access systems, home automation, HVAC systems, and industrial controls User’s Manual 5 1.4 Development and Evaluation Tools 1.4.1 RCM3305 Series Development Kit The RCM3305 Series Development Kit contains the hardware you need to use your RCM3305 or RCM3315 module. • RCM3309 module. • Prototyping Board. • Universal AC adapter, 12 V DC, 1 A (includes Canada/Japan/U.S., Australia/N.Z., U.K., and European style plugs). • USB programming cable with 10-pin header. • Dynamic C CD-ROM, with complete product documentation on disk. • Getting Started instructions. • Accessory parts for use on the Prototyping Board. • Screwdriver and Cat. 5 Ethernet cables. • Rabbit 3000 Processor Easy Reference poster. • Registration card.

RCM3305 Series Development Kit 6 RabbitCore RCM3305/RCM3315 1.4.2 Software The RCM3305 and the RCM3315 are programmed using version 9.25 or later of Rabbit’s Dynamic C. A compatible version is included on the Development Kit CD-ROM. Dynamic C v. 9.60, which is required for the related RCM3309 and RCM3319 RabbitCore modules, includes the popular µC/OS-II real-time operating system, point-to-point protocol (PPP), FAT file system, RabbitWeb, and other select libraries that were previously sold as indidual Dynamic C modules. Rabbit also offers for purchase the Rabbit Embedded Security Pack featuring the Secure Sockets Layer (SSL) and a specific Advanced Encryption Standard (AES) library. In addition to the Web-based technical support included at no extra charge, a one-year telephonebased technical support subscription is also available for purchase. Visit our Web site at www.rabbit.com for further information and complete documentation, or contact your Rabbit sales representative or authorized distributor. 1.4.3 Connectivity Interface Kits Rabbit has available a Connector Adapter Board. • Connector Adapter Board (Part No. 151-0114)—allows you to plug the RCM3305/ RCM3315 whose headers have a 2 mm pitch into header sockets with a 0.1" pitch. Visit our Web site at www.rabbit.com or contact your Rabbit sales representative or authorized distributor for further information. 1.4.4 Online Documentation The online documentation is installed along with Dynamic C, and an icon for the documentation menu is placed on the workstation’s desktop. Double-click this icon to reach the menu. If the icon is missing, use your browser to find and load default.htm in the docs folder, found in the Dynamic C installation folder. The latest versions of all documents are always available for free, unregistered download from our Web sites as well. User’s Manual 7 8 RabbitCore RCM3305/RCM3315 2. GETTING STARTED This chapter describes how to set up and use an RCM3305 series module and the Prototyping Board included in the Development Kit. NOTE: It is assumed that you have a Development Kit. If you purchased an RCM3305 series module by itself, you will have to adapt the information in this chapter and elsewhere to your test and development setup. 2.1 Install Dynamic C To develop and debug programs for an RCM3305 series module (and for all other Rabbit hardware), you must install and use Dynamic C. If you have not yet installed Dynamic C version 9.25 (or a later version), do so now by inserting the Dynamic C CD from the Development Kit in your PC’s CD-ROM drive. If autorun is enabled, the CD installation will begin automatically. If autorun is disabled or the installation otherwise does not start, use the Windows Start | Run menu or Windows Disk Explorer to launch setup.exe from the root folder of the CD-ROM. The installation program will guide you through the installation process. Most steps of the process are self-explanatory. Dynamic C uses a COM (serial) port to communicate with the target development system. The installation allows you to choose the COM port that will be used. The default selection is COM1. You may select any available port for Dynamic C’s use. If you are not certain which port is available, select COM1. This selection can be changed later within Dynamic C. NOTE: The installation utility does not check the selected COM port in any way. Specifying a port in use by another device (mouse, modem, etc.) may lead to a message such as "could not open serial port" when Dynamic C is started. Once your installation is complete, you will have up to three icons on your PC desktop. One icon is for Dynamic C, one opens the documentation menu, and the third is for the Rabbit Field Utility, a tool used to download precompiled software to a target system. If you have purchased the optional Dynamic C Rabbit Embedded Security Pack, install it after installing Dynamic C. You must install the Rabbit Embedded Security Pack in the same directory where Dynamic C was installed. User’s Manual 9 2.2 Hardware Connections There are three steps to connecting the Prototyping Board for use with Dynamic C and the sample programs: 1. Attach the RCM3305 series RabbitCore module to the Prototyping Board. 2. Connect the programming cable between the RCM3305 series RabbitCore module and the workstation PC. 3.

Connect Programming Cable and Power Supply NOTE: Be sure to use the serial programming cable (part number 101-0542)—the programming cable has blue shrink wrap around the RS-232 converter section located in the middle of the cable. The USB programming cable and programming cables with clear or red shrink wrap from other Rabbit kits are not designed to work with RCM3305/ RCM3315 modules. Connect the other end of the programming cable to a COM port on your PC. NOTE: It may be possible to use an RS-232/USB converter with the serial programming described in this section. An RS-232/USB converter (part number 20-151-0178) is available through the Web store. Note that not all RS-232/USB converters work with Dynamic C. 12 RabbitCore RCM3305/RCM3315 2.2.3 Step 3 — Connect Power When all other connections have been made, you can connect power to the Prototyping Board. If you have the universal power supply, prepare the AC adapter for the country where it will be used by selecting the plug. The RCM3305 Series Development Kit presently includes Canada/Japan/U.S., Australia/N.Z., U.K., and European style plugs. Snap in the top of the plug assembly into the slot at the top of the AC adapter as shown in Figure 3(a), then press down on the spring-loaded clip below the plug assembly to allow the plug assembly to click into place. Depending on the style of adapter, connect the AC adapter to 3-pin header J2 or jack J1 on the Prototyping Board as shown in Figure 3(a) or Figure 3(b). Plug in the AC adapter. The red CORE LED on the Prototyping Board should light up. The RCM3305 series RabbitCore module and the Prototyping Board are now ready to be used. NOTE: A RESET button is provided on the Prototyping Board to allow a hardware reset without disconnecting power. 2.2.3.1 Alternate Power-Supply Connections All Development Kits sold up to May, 2008, included a header connector that may be used to connect your power supply to 3-pin header J2 on the Prototyping Board. The connector may be attached either way as long as it is not offset to one side—the center pin of J2 is always connected to the positive terminal, and either edge pin is negative. The power supply should deliver 8 V to 30 V DC at 8 W. User’s Manual 13 2.3 Starting Dynamic C NOTE: Dynamic C v. 9.60 or a later version is required if you are using an RCM3309 or an RCM3319 RabbitCore module. Once the RCM3305 series module is connected as described in the preceding pages, start Dynamic C by double-clicking on the Dynamic C icon on your desktop or in your Start menu. Select Code and BIOS in Flash, Run in RAM on the “Compiler” tab in the Dynamic C Options > Project Options menu. Click OK. If you are using a USB port to connect your computer to the RCM3305/RCM3315 module, choose Options > Project Options and select “Use USB to Serial Converter” on the Communications tab. Click OK. 2.4 Run a Sample Program Use the File menu to open the sample program PONG.C, which is in the Dynamic C SAMPLES folder. Press function key F9 to compile and run the program. The STDIO window will open on your PC and will display a small square bouncing around in a box. This program shows that the CPU is working. The sample program described in Section 6.5, “Run the PINGME.C Sample Program,” tests the TCP/IP portion of the board. 2.4.1 Troubleshooting If Dynamic C cannot find the target system (error message "No Rabbit Processor Detected."): • Check that the RCM3305 series module is powered correctly — the red CORE LED on the Prototyping Board should be lit when the module is mounted on the Prototyping Board and the AC adapter is plugged in. • Check both ends of the programming cable to ensure that they are firmly plugged into the PC and the PROG connector, not the DIAG connector, is plugged in to the programming port on the RCM3305 series module with the marked (colored) edge of the programming cable towards pin 1 of the programming header. • Ensure that the RCM3305 series module is firmly and correctly installed in its connectors on the Prototyping Board. • Dynamic C uses the COM port or USB port specified during installation. Select a different COM port within Dynamic C. From the Options menu, select Project Options, then select Communications. Select another COM port from the list, then click OK. Press to force Dynamic C to recompile the BIOS. If Dynamic C still reports it is unable to locate the target system, repeat the above steps until you locate the COM port used by the programming cable. • If you get an error message when you plugged the programming cable into a USB port, you will have to install USB drivers. Drivers for Windows XP are available in the Dynamic C Drivers\Rabbit USB Programming Cable\WinXP_2K folder — double-click DPInst.exe to install the USB drivers. Drivers for other operating systems are available online at www.ftdichip.com/Drivers/VCP.htm. 14 RabbitCore RCM3305/RCM3315 If Dynamic C appears to compile the BIOS successfully, but you then receive a communication error message when you compile and load the sample program, it is possible that your PC cannot handle the higher program-loading baud rate. Try changing the maximum download rate to a slower baud rate as follows. • Locate the Serial Options dialog in the Dynamic C Options > Project Options > Communications menu. Select a slower Max download baud rate. If a program compiles and loads, but then loses target communication before you can begin debugging, it is possible that your PC cannot handle the default debugging baud rate. Try lowering the debugging baud rate as follows. • Locate the Serial Options dialog in the Dynamic C Options > Project Options > Communications menu. Choose a lower debug baud rate. 2.5 Where Do I Go From Here? If the sample program ran fine, you are now ready to go on to other sample programs and to develop your own applications. The source code for the sample programs is provided to allow you to modify them for your own use. The RCM3305/RCM3315 User’s Manual also provides complete hardware reference information and describes the software function calls for the RCM3305 and the RCM3315, the Prototyping Board, and the optional LCD/keypad module. The RCM3309/RCM3319 User’s Manual also provides complete hardware reference information and describes the software function calls for the RCM3309 and the RCM3319, the Prototyping Board, and the optional LCD/keypad module. For advanced development topics, refer to the Dynamic C User’s Manual and the Dynamic C TCP/IP User’s Manual, also in the online documentation set. 2.5.1 Technical Support NOTE: If you purchased your RCM3305 series module through a distributor or through a Rabbit partner, contact the distributor or partner first for technical support.

User’s Manual 15 16 RabbitCore RCM3305/RCM3315 3. RUNNING SAMPLE PROGRAMS To develop and debug programs for the RCM3305/RCM3315 (and for all other Rabbit hardware), you must install and use Dynamic C. 3.1 Introduction To help familiarize you with the RCM3305 and RCM3315 modules, Dynamic C includes several sample programs. Loading, executing and studying these programs will give you a solid hands-on overview of the RCM3305/RCM3315’s capabilities, as well as a quick start using Dynamic C as an application development tool. NOTE: The sample programs assume that you have at least an elementary grasp of the C programming language. If you do not, see the introductory pages of the Dynamic C User’s Manual for a suggested reading list. More complete information on Dynamic C is provided in the Dynamic C User’s Manual. In order to run the sample programs discussed in this chapter and elsewhere in this manual, 1. Your RCM3305/RCM3315 must be plugged in to the Prototyping Board as described in Chapter 2, “Getting Started.” 2. Dynamic C must be installed and running on your PC. 3. The programming cable must connect the programming header on the RCM3305/ RCM3315 to your PC. 4. Power must be applied to the RCM3305/RCM3315 through the Prototyping Board. Refer to Chapter 2, “Getting Started,” if you need further information on these steps. To run a sample program, open it with the File menu, then press function key F9 to compile and run the program. The RCM3305/RCM3315 must be in Program Mode (see Figure 8) and must be connected to a PC using the programming cable. User’s Manual 17 3.2 Sample Programs Of the many sample programs included with Dynamic C, several are specific to the RCM3305 and the RCM3315. Sample programs illustrating the general operation of the RCM3305/RCM3315, serial communication, and the serial flash are provided in the SAMPLES\RCM3300 folder. Each sample program has comments that describe the purpose and function of the program. Follow the instructions at the beginning of the sample program. Note that the RCM3305/RCM3315 must be installed on the Prototyping Board when using the sample programs described in this chapter. • CONTROLLED.c—Demonstrates use of the digital inputs by having you turn the LEDs on the Prototyping Board on or off from the STDIO window on your PC. Once you compile and run CONTROLLED.C, the following display will appear in the Dynamic C STDIO window. Press “2” or “3” or “4”or “5”on your keyboard to select LED DS3 or DS4 or DS5 or DS6 on the Prototyping Board. Then follow the prompt in the Dynamic C STDIO window to turn the LED on or off. • FLASHLED.c—Demonstrates assembly-language program by flashing the USR LED on the RCM3305/RCM3315 and LEDs DS3, DS4, DS5, and DS6 on the Prototyping Board. • SWRELAY.c—Demonstrates the relay-switching function call using the relay installed on the Prototyping Board through screw-terminal header J17. • TOGGLESWITCH.c—Uses costatements to detect switches S2 and S3 using debouncing. The corresponding LEDs (DS3 and DS4) will turn on or off. Once you have loaded and executed these five programs and have an understanding of how Dynamic C and the RCM3305/RCM3315 modules interact, you can move on and try the other sample programs, or begin building your own. 18 RabbitCore RCM3305/RCM3315 3.2.1 Use of Serial Flash 3.2.1.1 Onboard Serial Flash The following sample programs can be found in the SAMPLES\RCM3300\SerialFlash folder. • SFLASH_INSPECT.c—This program is a handy utility for inspecting the contents of a serial flash chip. When the sample program starts running, it attempts to initialize a serial flash chip on Serial Port B. Once a serial flash chip is found, the user can perform two different commands to either print out the contents of a specified page or clear (set to zero) all the bytes in a specified page. • SFLASH_LOG.c—This program runs a simple Web server and stores a log of hits in the serial flash. This log can be viewed and cleared from a browser. 3.2.1.2 SF1000 Serial Flash Card The following sample program can be found in the SAMPLES\RCM3300\SF1000 folder. • SERFLASHTEST.c—An optional SF1000 Serial Flash card is required to run this demonstration. Install the Serial Flash card into socket J11 on the Prototyping Board. This sample program demonstrates how to read and write from/to the Serial Flash card. 3.2.2 Serial Communication The following sample programs can be found in the SAMPLES\RCM3300\SERIAL folder. • FLOWCONTROL.C—This program demonstrates hardware flow control by configuring Serial Port F for CTS/RTS with serial data coming from TxE (Serial Port E) at 115,200 bps. One character at a time is received and is displayed in the STDIO window. To set up the Prototyping Board, you will need to tie TxE and RxE together on the RS-232 header at J14, and you will also tie TxF and RxF together as shown in the diagram. J14 TxE RxE GND TxF RxF 485+ GND 485– A repeating triangular pattern should print out in the STDIO window. The program will periodically switch flow control on or off to demonstrate the effect of no flow control. • PARITY.C—This program demonstrates the use of parity modes by repeatedly sending byte values 0–127 from Serial Port E to Serial Port F. The program will switch between generating parity or not on Serial Port E. Serial Port F will always be checking parity, so parity errors should occur during every other sequence. To set up the Prototyping Board, you will need to tie TxE and RxF together on the RS-232 header at J14 as shown in the diagram. The Dynamic C STDIO window will display the error sequence. User’s Manual J14 TxE RxE GND TxF RxF 485+ GND 485– 19 • SIMPLE3WIRE.C—This program demonstrates basic RS-232 serial communication. Lower case characters are sent by TxE, and are received by RxF. The characters are converted to upper case and are sent out by TxF, are received by RxE, and are displayed in the Dynamic C STDIO window. To set up the Prototyping Board, you will need to tie TxE and RxF together on the RS-232 header at J14, and you will also tie RxE and TxF together as shown in the diagram.

J14 TxE RxE GND TxF RxF 485+ GND 485– Once you have compiled and run this program, you can test flow control by disconnecting TxF from RxF while the program is running. Characters will no longer appear in the STDIO window, and will display again once TxF is connected back to RxF. • SWITCHCHAR.C—This program transmits and then receives an ASCII string on Serial Ports E and F. It also displays the serial data received from both ports in the STDIO window.

J14 TxE RxE GND TxF RxF 485+ GND 485– Once you have compiled and run this program, press and release S2 and S3 on the Prototyping Board. The data sent between the serial ports will be displayed in the STDIO window. Two sample programs, SIMPLE485MASTER.C and SIMPLE485SLAVE.C, are available to illustrate RS-485 master/slave communication. To run these sample programs, you will need a second Rabbit-based system with RS-485—another Rabbit single-board computer or RabbitCore module may be used as long as you use the master or slave sample program associated with that board. Before running either of these sample programs on the RCM3305/RCM3315 assembly, make sure pins 1–2 and pins 5–6 are jumpered together on header JP5 to use the RS-485 bias and termination resistors. The sample programs use Serial Port C as the RS-485 serial port, and they use PD7 to enable/disable the RS-485 transmitter. 20 RabbitCore RCM3305/RCM3315 The RS-485 connections between the slave and master devices are as follows. • RS485+ to RS485+ • RS485– to RS485– • GND to GND • SIMPLE485MASTER.C—This program demonstrates a simple RS-485 transmission of lower case letters to a slave. The slave will send back converted upper case letters back to the master and display them in the STDIO window. Use SIMPLE485SLAVE.C to program the slave. • SIMPLE485SLAVE.C—This program demonstrates a simple RS-485 transmission of lower case letters to a master.

Use SIMPLE485MASTER.C to program the master. 3.2.3 Real-Time Clock If you plan to use the real-time clock functionality in your application, you will need to set the real-time clock. Set the real-time clock using the SETRTCKB.C sample program from the Dynamic C SAMPLES\RTCLOCK folder, using the onscreen prompts. The RTC_ TEST.C sample program in the Dynamic C SAMPLES\RTCLOCK folder provides additional examples of how to read and set the real-time clock. 3.2.4 RabbitNet Sample programs are available for each RabbitNet peripheral card, and can be found in the Dynamic C SAMPLES\RabbitNet folder. When you run any of these sample programs in conjunction with the RCM3305/RCM3315 and the Prototyping Board, you need to add the line #use rcm33xx.lib at the beginning of the sample program. TIP: You need to add #use rcm33xx.lib at the beginning of any sample program that is not in the Dynamic C SAMPLES\RCM3300 folder. 3.2.5 Other Sample Programs Section 6.6 describes the TCP/IP sample programs, and Appendix C.7 provides sample programs for the optional LCD/keypad module that can be installed on the Prototyping Board.

PB0, PC4, and PC5 are used for the SPI interface to the serial flash on the RCM3305 and the RCM3315. Visit the Web site for further information. Headers J3 and J4 are standard 2 × 34 headers with a nominal 2 mm pitch. An RJ-45 Ether- net port is also included with the RCM3305/RCM3315. Pins 29–32 on header J3 are configured using 0 Ω resistors at locations JP4, JP5, JP6, and JP7 to be PD2, PD3, PD6, and PD7 respectively. They may also be reconfigured to carry the Ethernet signals TPI+, TPI–, TPO+, and TPO–. Pins 33 and 34 on header J3 are wired to carry the LINK and ACT signals that illuminated the corresponding LEDs on the RCM3305/RCM3315 module. These signals may be “disconnected” by removing 0 Ω surface-mount resistors R41 and R42. See Appendix A.5 for more information about the locations of these surface-mount resistors. 24 RabbitCore RCM3305/RCM3315 Figure 6 shows the use of the Rabbit 3000 microprocessor ports in the RCM3305/ RCM3315 modules.

When using pins 33–34 on header J3 to drive LEDs, these pins can handle a sinking current of up to 8 mA. 2. The VRAM voltage is temperature-dependent. If the VRAM voltage drops below about 1.2 V to 1.5 V, the contents of the battery-backed SRAM may be lost. If VRAM drops below 1.0 V, the 32 kHz oscillator could stop running. Pay careful attention to this voltage if you draw any current from this pin. 28 RabbitCore RCM3305/RCM3315 4.1.1 Memory I/O Interface The Rabbit 3000 address lines (A0–A18) and all the data lines (D0–D7) are routed internally to the onboard flash memory and SRAM chips. I/0 write (/IOWR) and I/0 read (/IORD) are available for interfacing to external devices. Parallel Port A can also be used as an external I/O data bus to isolate external I/O from the main data bus. Parallel Port B pins PB2–PB5 and PB7 can also be used as an external address bus. When using the external I/O bus for a digital output or the LCD/keypad module on the Prototyping Board, or for any other reason, you must add the following line at the beginning of your program. #define PORTA_AUX_IO // required to enable external I/O bus 4.1.2 Other Inputs and Outputs The status, /RESET_IN, SMODE0, and SMODE1 I/O are normally associated with the programming port. Since the status pin is not used by the system once a program has been downloaded and is running, the status pin can then be used as a general-purpose CMOS output. The programming port is described in more detail in Section 4.2.3. /RES is an output from the reset circuitry that can be used to reset external peripheral devices. 4.1.3 LEDs The RCM3305/RCM3315 has three Ethernet status LEDs located beside the RJ-45 Ethernet jack—these are discussed in Section 4.2. Addiitionally, there are two other LEDs. The SF LED at DS3 blinks when data are being written to or read from the flash mass-storage device. The red USR LED at DS3 is a userprogrammable LED, which is controlled by PD0 on the Rabbit 3000’s Parallel Port D. The sample program FLASHLED.C provided in the Dynamic C SAMPLES\RCM3300 folder shows how to set up and use this user-programmable LED. User’s Manual 29 4.2 Serial Communication The RCM3305/RCM3315 does not have any serial transceivers directly on the board. However, a serial interface may be incorporated into the board the RCM3305/RCM3315 is mounted on. For example, the Prototyping Board has RS-232 and RS-485 transceiver chips. 4.2.1 Serial Ports There are six serial ports designated as Serial Ports A, B, C, D, E, and F. All six serial ports can operate in an asynchronous mode up to the baud rate of the system clock divided by 8. An asynchronous port can handle 7 or 8 data bits. A 9th bit address scheme, where an additional bit is sent to mark the first byte of a message, is also supported. Serial Port A is normally used as a programming port, but may be used either as an asynchronous or as a clocked serial port once the RCM3305/RCM3315 has been programmed and is operating in the Run Mode. Serial Port B is used to communicate with the serial flash on the RCM3305/RCM3315 and is not available for other use. Serial Ports C and D can also be operated in the clocked serial mode. In this mode, a clock line synchronously clocks the data in or out. Either of the two communicating devices can supply the clock. Serial Ports E and F can also be configured as HDLC serial ports. The IrDA protocol is also supported in SDLC format by these two ports. 30 RabbitCore RCM3305/RCM3315 4.2.2 Ethernet Port Figure 7 shows the pinout for the RJ-45 Ethernet port (J2). Note that some Ethernet connectors are numbered in reverse to the order used here. ETHERNET 1 8 1. 2. 3. 6. RJ-45 Plug E_Tx+ E_Tx– E_Rx+ E_Rx– RJ-45 Jack Figure 7. RJ-45 Ethernet Port Pinout The RJ-45 connector is shielded to minimize EMI effects to/from the Ethernet signals. Three Ethernet status LEDs are located beside the RJ-45 Ethernet jack: ACT, LINK, and SPEED. The yellow ACT LED at DS1 indicates network activity. The green LINK LED at DS2 indicates that the RCM3305/RCM3315 is connected to a working network. The green SPEED LED at DS4 is on to indicate when the RCM3305/RCM3315 is connected to a 100Base-T Ethernet connection. User’s Manual 31 4.2.3 Programming Port The RCM3305/RCM3315 is programmed either through the serial programming port, which is accessed using header J1, or through the Ethernet jack. The RabbitLink may be used to provide a serial connection via the RabbitLink’s Ethernet jack. The programming port uses the Rabbit 3000’s Serial Port A for communication; Serial Port A is not used when programming is done over an Ethernet connection via the Dynamic C download manager or the remote application update. Dynamic C uses the programming port to download and debug programs. The programming port is also used for the following operations. • Cold-boot the Rabbit 3000 on the RCM3305/RCM3315 after a reset. • Remotely download and debug a program over an Ethernet connection using the RabbitLink EG2110. • Fast copy designated portions of flash memory from one Rabbit-based board (the master) to another (the slave) using the Rabbit Cloning Board. In addition to Serial Port A, the Rabbit 3000 startup-mode (SMODE0, SMODE1), status, and reset pins are available on the programming port. The two startup mode pins determine what happens after a reset—the Rabbit 3000 is either cold-booted or the program begins executing at address 0x0000. The status pin is used by Dynamic C to determine whether a Rabbit microprocessor is present. The status output has three different programmable functions: 1. It can be driven low on the first op code fetch cycle. 2. It can be driven low during an interrupt acknowledge cycle. 3. It can also serve as a general-purpose CMOS output. The /RESET_IN pin is an external input that is used to reset the Rabbit 3000 and the RCM3305/RCM3315 onboard peripheral circuits. The serial programming port can be used to force a hard reset on the RCM3305/RCM3315 by asserting the /RESET_IN signal. Alternate Uses of the Programming Port All three clocked Serial Port A signals are available as • a synchronous serial port • an asynchronous serial port, with the clock line usable as a general CMOS I/O pin The programming port may also be used as a serial port once the application is running. The SMODE pins may then be used as inputs and the status pin may be used as an output. Refer to the Rabbit 3000 Microprocessor User’s Manual for more information. 32 RabbitCore RCM3305/RCM3315 4.3 Programming Cable The programming cable is used to connect the programming port of the RCM3305/ RCM3315 to a PC serial COM port. The programming cable converts the RS-232 voltage levels used by the PC serail port to the CMOS voltage levels used by the Rabbit 3000. When the PROG connector on the programming cable is connected to the RCM3305/ RCM3315 programming port, programs can be downloaded and debugged over the serial interface. The DIAG connector of the programming cable may be used on header J1 of the RCM3305/ RCM3315 with the RCM3305/RCM3315 operating in the Run Mode. This allows the programming port to be used as a regular serial port. 4.3.1 Changing Between Program Mode and Run Mode The RCM3305/RCM3315 is automatically in Program Mode when the PROG connector on the programming cable is attached, and is automatically in Run Mode when no programming cable is attached. When the Rabbit 3000 is reset, the operating mode is determined by the state of the SMODE pins. When the programming cable’s PROG connector is attached, the SMODE pins are pulled high, placing the Rabbit 3000 in the Program Mode. When the programming cable’s PROG connector is not attached, the SMODE pins are pulled low, causing the Rabbit 3000 to operate in the Run Mode.

Figure 8. Switching Between Program Mode and Run Mode User’s Manual 33 A program “runs” in either mode, but can only be downloaded and debugged when the RCM3305/RCM3315 is in the Program Mode. Refer to the Rabbit 3000 Microprocessor User’s Manual for more information on the programming port. 4.3.2 Standalone Operation of the RCM3305/RCM3315 The RCM3305/RCM3315 must be programmed via the Prototyping Board or via a similar arrangement on a customer-supplied board. Once the RCM3305/RCM3315 has been programmed successfully, remove the programming cable from the programming connector and reset the RCM3305/RCM3315. The RCM3305/RCM3315 may be reset by cycling the power off/on or by pressing the RESET button on the Prototyping Board. The RCM3305/ RCM3315 module may now be removed from the Prototyping Board for end-use installation. CAUTION: Disconnect power to the Prototyping Board or other boards when removing or installing your RCM3305/RCM3315 module to protect against inadvertent shorts across the pins or damage to the RCM3305/RCM3315 if the pins are not plugged in correctly. Do not reapply power until you have verified that the RCM3305/RCM3315 module is plugged in correctly. 34 RabbitCore RCM3305/RCM3315 4.4 Other Hardware 4.4.1 Clock Doubler The RCM3305/RCM3315 takes advantage of the Rabbit 3000 microprocessor’s internal clock doubler. A built-in clock doubler allows half-frequency crystals to be used to reduce radiated emissions. The 44.2 MHz frequency specified for the RCM3305/RCM3315 is generated using a 22.12 MHz resonator. The clock doubler may be disabled if 44.2 MHz clock speeds are not required. This will reduce power consumption and further reduce radiated emissions. The clock doubler is disabled with a simple configuration macro as shown below. 1. Select the “Defines” tab from the Dynamic C Options > Project Options menu. 2. Add the line CLOCK_DOUBLED=0 to always disable the clock doubler. The clock doubler is enabled by default, and usually no entry is needed. If you need to specify that the clock doubler is always enabled, add the line CLOCK_DOUBLED=1 to always enable the clock doubler. 3. Click OK to save the macro. The clock doubler will now remain off whenever you are in the project file where you defined the macro. 4.4.2 Spectrum Spreader The Rabbit 3000 features a spectrum spreader, which helps to mitigate EMI problems. The spectrum spreader is on by default, but it may also be turned off or set to a stronger setting. The means for doing so is through a simple configuration macro as shown below. 1. Select the “Defines” tab from the Dynamic C Options > Project Options menu. 2. Normal spreading is the default, and usually no entry is needed. If you need to specify normal spreading, add the line ENABLE_SPREADER=1 For strong spreading, add the line ENABLE_SPREADER=2 To disable the spectrum spreader, add the line ENABLE_SPREADER=0 NOTE: The strong spectrum-spreading setting is unnecessary for the RCM3305/RCM3315. 3. Click OK to save the macro. The spectrum spreader will now be set to the state specified by the macro value whenever you are in the project file where you defined the macro. NOTE: Refer to the Rabbit 3000 Microprocessor User’s Manual for more information on the spectrum-spreading setting and the maximum clock speed. User’s Manual 35 4.5 Memory 4.5.1 SRAM RCM3305/RCM3315 boards have 512K of program-execution fast SRAM at U11. The program-execution SRAM is not battery-backed. There are 512K of battery-backed data SRAM installed at U10. 4.5.2 Flash EPROM RCM3305/RCM3315 boards also have 512K of flash EPROM at U9. NOTE: Rabbit recommends that any customer applications should not be constrained by the sector size of the flash EPROM since it may be necessary to change the sector size in the future. Writing to arbitrary flash memory addresses at run time is also discouraged. Instead, use a portion of the “user block” area to store persistent data. The functions writeUserBlock() and readUserBlock() are provided for this. Refer to the Rabbit 3000 Microprocessor Designer’s Handbook and the Dynamic C Function Reference Manual for additional information. 4.5.3 Serial Flash A serial flash is supplied on the RCM3305 and the RCM3315 to store data and Web pages. Sample programs in the SAMPLES\RCM3300 folder illustrate the use of the serial flash. These sample programs are described in Section 3.2.1, “Use of Serial Flash.” 4.5.4 Dynamic C BIOS Source Files The Dynamic C BIOS source files handle different standard RAM and flash EPROM sizes automatically. 36 RabbitCore RCM3305/RCM3315 5. SOFTWARE REFERENCE Dynamic C is an integrated development system for writing embedded software. It runs on an IBM-compatible PC and is designed for use with controllers based on the Rabbit microprocessor. Chapter 5 describes the libraries and function calls related to the RCM3305/RCM3315. 5.1 More About Dynamic C Dynamic C has been in use worldwide since 1989. It is specially designed for programming embedded systems, and features quick compile and interactive debugging. A complete reference guide to Dynamic C is contained in the Dynamic C User’s Manual. You have a choice of doing your software development in the flash memory or in the static SRAM included on the RCM3305/RCM3315. The flash memory and SRAM options are selected with the Options > Program Options > Compiler menu. The advantage of working in RAM is to save wear on the flash memory, which is limited to about 100,000 write cycles. The disadvantage is that the code and data might not both fit in RAM. NOTE: An application should be run from the program execution SRAM after the programming cable is disconnected. Your final code must always be stored in flash memory for reliable operation. RCM3305/RCM3315 modules running at 44.2 MHz have a fast program execution SRAM that is not battery-backed. Select Code and BIOS in Flash, Run in RAM from the Dynamic C Options > Project Options > Compiler menu to store the code in flash and copy it to the fast program execution SRAM at run-time to take advantage of the faster clock speed. This option optimizes the performance of RCM3305/RCM3315 modules running at 44.2 MHz. NOTE: Do not depend on the flash memory sector size or type in your program logic. The RCM3305/RCM3315 and Dynamic C were designed to accommodate flash devices with various sector sizes in response to the volatility of the flash-memory market. Developing software with Dynamic C is simple. Users can write, compile, and test C and assembly code without leaving the Dynamic C development environment. Debugging occurs while the application runs on the target. Alternatively, users can compile a program to an image file for later loading. Dynamic C runs on PCs under Windows 2000 and later—see Rabbit’s Technical Note TN257, Running Dynamic C® With Windows Vista®, User’s Manual 37 for additional information if you are using a Dynamic C release prior to v. 9.60 under Windows Vista. Programs can be downloaded at baud rates of up to 460,800 bps after the program compiles. Dynamic C has a number of standard features. • Full-feature source and/or assembly-level debugger, no in-circuit emulator required. • Royalty-free TCP/IP stack with source code and most common protocols. • Hundreds of functions in source-code libraries and sample programs: X Exceptionally fast support for floating-point arithmetic and transcendental functions. X RS-232 and RS-485 serial communication. X Analog and digital I/O drivers. X I2C, SPI, GPS, file system. X LCD display and keypad drivers. • Powerful language extensions for cooperative or preemptive multitasking • Loader utility program to load binary images into Rabbit targets in the absence of Dynamic C. • Provision for customers to create their own source code libraries and augment on-line help by creating “function description” block comments using a special format for library functions. • Standard debugging features: X Breakpoints—Set breakpoints that can disable interrupts. X Single-stepping—Step into or over functions at a source or machine code level, µC/OS-II aware. X Code disassembly—The disassembly window displays addresses, opcodes, mnemonics, and machine cycle times. Switch between debugging at machine-code level and source-code level by simply opening or closing the disassembly window. X Watch expressions—Watch expressions are compiled when defined, so complex expressions including function calls may be placed into watch expressions. Watch expressions can be updated with or without stopping program execution. X Register window—All processor registers and flags are displayed. The contents of general registers may be modified in the window by the user. X Stack window—shows the contents of the top of the stack. X Hex memory dump—displays the contents of memory at any address. X STDIO window—printf outputs to this window and keyboard input on the host PC can be detected for debugging purposes. printf output may also be sent to a serial port or file. 38 RabbitCore RCM3305/RCM3315 5.1.1 Developing Programs Remotely with Dynamic C Dynamic C is an integrated development environment that allows you to edit, compile, and debug your programs. Dynamic C has the ability to allow programming over the Internet or local Ethernet. This is accomplished in one of two ways. 1. Via the Rabbit RabbitLink, which allows a Rabbit-based target to have programs downloaded to it and debugged with the same ease as exists when the target is connected directly to a PC. 2. The RCM3305/RCM3315 has a featured remote application update written specifically to allow the RCM3305/RCM3315 to be programmed over the Internet or local Ethernet. These programs, DLP_STATIC.C and DLP_WEB.C, are available in the Dynamic C SAMPLES\RCM3300\RemoteApplicationUpdate folder. Complete information on the use of these programs is provided in the Remote Application Update instructions, which are available with the online documentation. Dynamic C provides sample programs to illustrate the use of a download manager. User’s Manual 39 5.2 Dynamic C Functions 5.2.1 Digital I/O The RCM3305/RCM3315 was designed to interface with other systems, and so there are no drivers written specifically for the I/O. The general Dynamic C read and write functions allow you to customize the parallel I/O to meet your specific needs. For example, use WrPortI(PEDDR, &PEDDRShadow, 0x00); to set all the Port E bits as inputs, or use WrPortI(PEDDR, &PEDDRShadow, 0xFF); to set all the Port E bits as outputs. When using the external I/O bus on the Rabbit 3000 chip, add the line #define PORTA_AUX_IO // required to enable external I/O bus to the beginning of any programs using the external I/O bus. The sample programs in the Dynamic C SAMPLES/RCM3300 folder provide further examples. 5.2.2 SRAM Use The RCM3305/RCM3315 have a battery-backed data SRAM and a program-execution SRAM. Dynamic C provides the protected keyword to identify variables that are to be placed into the battery-backed SRAM. The compiler generates code that creates a backup copy of a protected variable before the variable is modified. If the system resets while the protected variable is being modified, the variable's value can be restored when the system restarts. The sample code below shows how a protected variable is defined and how its value can be restored. protected nf_device nandFlash; int main() { ... _sysIsSoftReset(); // restore any protected variables The bbram keyword may also be used instead if there is a need to store a variable in battery-backed SRAM without affecting the performance of the application program. Data integrity is not assured when a reset or power failure occurs during the update process. Additional information on bbram and protected variables is available in the Dynamic C User’s Manual. 40 RabbitCore RCM3305/RCM3315 5.2.3 Serial Communication Drivers Library files included with Dynamic C provide a full range of serial communications support. The RS232.LIB library provides a set of circular-buffer-based serial functions. The PACKET.LIB library provides packet-based serial functions where packets can be delimited by the 9th bit, by transmission gaps, or with user-defined special characters. Both libraries provide blocking functions, which do not return until they are finished transmitting or receiving, and nonblocking functions, which must be called repeatedly until they are finished, allowing other functions to be performed between calls. For more information, see the Dynamic C Function Reference Manual and Technical Note TN213, Rabbit Serial Port Software. 5.2.4 TCP/IP Drivers The TCP/IP drivers are located in the LIB\TCPIP folder. Complete information on these libraries and the TCP/IP functions is provided in the Dynamic C TCP/IP User’s Manual. 5.2.5 Serial Flash Drivers The Dynamic C SerialFlash\SFLASH.LIB library is used to interface to serial flash memory devices on an SPI bus such as the serial flash on board the RCM3305 and the RCM3315, which use Serial Port B as an SPI port. The library has two sets of function calls—the first is maintained for compatibility with previous versions of the SFLASH.LIB library. The functions are all blocking and only work for single flash devices. The new functions, which should be used for the RCM3305/RCM3315, make use of an sf_device structure as a handle for a specific serial flash device. This allows multiple devices to be used by an application. More information on these function calls is available in the Dynamic C Function Reference Manual. User’s Manual 41 5.2.6 Prototyping Board Functions The functions described in this section are for use with the Prototyping Board features. The source code is in the Dynamic C SAMPLES\RCM3300\RCM33xx.LIB library if you need to modify it for your own board design. The RCM33xx.LIB library is supported by the RN_CFG_RCM33.LIB—library, which is used to configure the RCM3305/RCM3315 for use with RabbitNet peripheral boards on the Prototyping Board. Other generic functions applicable to all devices based on Rabbit microprocessors are described in the Dynamic C Function Reference Manual. 5.2.6.1 Board Initialization void brdInit (void); Call this function at the beginning of your program.

SEE ALSO brdInit 5.2.6.4 Serial Communication void ser485Tx(void); Enables the RS-485 transmitter. Transmitted data are echoed back into the receive data buffer. The echoed data may be used as an indicator for disabling the transmitter by using one of the following methods: Byte mode—disable the transmitter after the same byte that is transmitted is detected in the receive data buffer. Block data mode—disable the transmitter after the same number of bytes transmitted are detected in the receive data buffer. Remember to call the serXopen() function before running this function. SEE ALSO ser485Rx void ser485Rx(void); Disables the RS-485 transmitter. This puts the device into the listen mode, which allows it to receive data from the RS-485 interface. Remember to call the serXopen() function before running this function. SEE ALSO ser485Tx User’s Manual 45 5.2.6.5 RabbitNet Port The function calls described in this section are used to configure the RabbitNet port on the Prototyping Board for use with RabbitNet peripheral cards. The user’s manual for the specific peripheral card you are using contains additional function calls related to the RabbitNet protocol and the individual peripheral card. Appendix E provides additional information about the RabbitNet. These RabbitNet peripheral cards are available at the present time. • Digital I/O Card (RN1100) • Relay Card (RN1400) • A/D Converter Card (RN1200) • Keypad/Display Interface (RN1600) • D/A Converter Card (RN1300) Before using the RabbitNet port, add the following lines at the start of your program. #define RN_MAX_DEV 10 // max number of devices #define RN_MAX_DATA 16 // max number of data bytes in any transaction #define RN_MAX_PORT 2 // max number of serial ports Set the following bits in RNSTATUSABORT to abort transmitting data after the status byte is returned. This does not affect the status byte and still can be interpreted.

USING THE TCP/IP FEATURES 6.1 TCP/IP Connections Programming and development can be done with the RCM3305/RCM3315 modules without connecting the Ethernet port to a network. However, if you will be running the sample programs that use the Ethernet capability or will be doing Ethernet-enabled development, you should connect the RCM3305/RCM3315 module’s Ethernet port at this time. Before proceeding you will need to have the following items. • If you don’t have Ethernet access, you will need at least a 10Base-T Ethernet card (available from your favorite computer supplier) installed in a PC. • Two RJ-45 straight-through Ethernet cables and a hub, or an RJ-45 crossover Ethernet cable. A straight-through and a crossover Ethernet cable are included in both the RCM3305/ RCM3315 Development Kit. Figure 9 shows how to identify the two cables based on the wires in the transparent RJ-45 connectors. Same color order in connectors StraightThrough Cable Different color order in connectors Crossover Cable Figure 9. How to Identify Straight-Through and Crossover Ethernet Cables Ethernet cables and a 10Base-T Ethernet hub are available from Rabbit in a TCP/IP tool kit. More information is available at www.rabbit.com. User’s Manual 49 Now you should be able to make your connections. 1. Connect the AC adapter and the programming cable as shown in Chapter 2, “Getting Started.” 2. Ethernet Connections There are four options for connecting the RCM3305/RCM3315 module to a network for development and runtime purposes. The first two options permit total freedom of action in selecting network addresses and use of the “network,” as no action can interfere with other users. We recommend one of these options for initial development. • No LAN — The simplest alternative for desktop development. Connect the RCM3305/RCM3315 module’s Ethernet port directly to the PC’s network interface card using an RJ-45 crossover cable. A crossover cable is a special cable that flips some connections between the two connectors and permits direct connection of two client systems. A standard RJ-45 network cable will not work for this purpose. • Micro-LAN — Another simple alternative for desktop development. Use a small Ethernet 10Base-T hub and connect both the PC’s network interface card and the RCM3305/RCM3315 module’s Ethernet port to it using standard network cables. The following options require more care in address selection and testing actions, as conflicts with other users, servers and systems can occur: • LAN — Connect the RCM3305/RCM3315 module’s Ethernet port to an existing LAN, preferably one to which the development PC is already connected. You will need to obtain IP addressing information from your network administrator. • WAN — The RCM3305/RCM3315 is capable of direct connection to the Internet and other Wide Area Networks, but exceptional care should be used with IP address settings and all network-related programming and development. We recommend that development and debugging be done on a local network before connecting a RabbitCore system to the Internet. TIP: Checking and debugging the initial setup on a micro-LAN is recommended before connecting the system to a LAN or WAN. The PC running Dynamic C does not need to be the PC with the Ethernet card. 3. Apply Power Plug in the AC adapter. The RCM3305/RCM3315 module and Prototyping Board are now ready to be used. 50 RabbitCore RCM3305/RCM3315 6.2 TCP/IP Primer on IP Addresses Obtaining IP addresses to interact over an existing, operating, network can involve a number of complications, and must usually be done with cooperation from your ISP and/or network systems administrator. For this reason, it is suggested that the user begin instead by using a direct connection between a PC and the RCM3305/RCM3315 using an Ethernet crossover cable or a simple arrangement with a hub. (A crossover cable should not be confused with regular straight through cables.) In order to set up this direct connection, the user will have to use a PC without networking, or disconnect a PC from the corporate network, or install a second Ethernet adapter and set up a separate private network attached to the second Ethernet adapter. Disconnecting your PC from the corporate network may be easy or nearly impossible, depending on how it is set up. If your PC boots from the network or is dependent on the network for some or all of its disks, then it probably should not be disconnected. If a second Ethernet adapter is used, be aware that Windows TCP/IP will send messages to one adapter or the other, depending on the IP address and the binding order in Microsoft products. Thus you should have different ranges of IP addresses on your private network from those used on the corporate network. If both networks service the same IP address, then Windows may send a packet intended for your private network to the corporate network. A similar situation will take place if you use a dial-up line to send a packet to the Internet. Windows may try to send it via the local Ethernet network if it is also valid for that network. The following IP addresses are set aside for local networks and are not allowed on the Internet: 10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255, and 192.168.0.0 to 192.168.255.255. The RCM3305/RCM3315 uses a 10/100Base-T type of Ethernet connection, which is the most common scheme. The RJ-45 connectors are similar to U.S. style telephone connectors, except they are larger and have 8 contacts. An alternative to the direct connection using a crossover cable is a direct connection using a hub. The hub relays packets received on any port to all of the ports on the hub. Hubs are low in cost and are readily available. The RCM3305/RCM3315 uses 10/100 Mbps Ethernet, so the hub or Ethernet adapter can be a 10 Mbps unit, a 100 Mbps unit, or a 10/100 Mbps unit. In a corporate setting where the Internet is brought in via a high-speed line, there are typically machines between the outside Internet and the internal network. These machines include a combination of proxy servers and firewalls that filter and multiplex Internet traffic. In the configuration below, the RCM3305/RCM3315 could be given a fixed address so any of the computers on the local network would be able to contact it. It may be possible to configure the firewall or proxy server to allow hosts on the Internet to directly contact the controller, but it would probably be easier to place the controller directly on the external network outside of the firewall. This avoids some of the configuration complications by sacrificing some security. User’s Manual 51 Hub(s) T1 in Adapter Ethernet Firewall Proxy Server Network Ethernet Typical Corporate Network RCM3305/RCM3315 System If your system administrator can give you an Ethernet cable along with its IP address, the netmask and the gateway address, then you may be able to run the sample programs without having to setup a direct connection between your computer and the RCM3305/ RCM3315. You will also need the IP address of the nameserver, the name or IP address of your mail server, and your domain name for some of the sample programs. 52 RabbitCore RCM3305/RCM3315 6.2.1 IP Addresses Explained IP (Internet Protocol) addresses are expressed as 4 decimal numbers separated by periods, for example: 216.103.126.155 10.1.1.6 Each decimal number must be between 0 and 255. The total IP address is a 32-bit number consisting of the 4 bytes expressed as shown above. A local network uses a group of adjacent IP addresses. There are always 2N IP addresses in a local network. The netmask (also called subnet mask) determines how many IP addresses belong to the local network. The netmask is also a 32-bit address expressed in the same form as the IP address. An example netmask is: 255.255.255.0 This netmask has 8 zero bits in the least significant portion, and this means that 28 addresses are a part of the local network. Applied to the IP address above (216.103.126.155), this netmask would indicate that the following IP addresses belong to the local network: 216.103.126.0 216.103.126.1 216.103.126.2 etc. 216.103.126.254 216.103.126.255 The lowest and highest address are reserved for special purposes. The lowest address (216.102.126.0) is used to identify the local network. The highest address (216.102.126.255) is used as a broadcast address. Usually one other address is used for the address of the gateway out of the network. This leaves 256 - 3 = 253 available IP addresses for the example given. User’s Manual 53 6.2.2 How IP Addresses are Used The actual hardware connection via an Ethernet uses Ethernet adapter addresses (also called MAC addresses). These are 48-bit addresses and are unique for every Ethernet adapter manufactured. In order to send a packet to another computer, given the IP address of the other computer, it is first determined if the packet needs to be sent directly to the other computer or to the gateway. In either case, there is an Ethernet address on the local network to which the packet must be sent. A table is maintained to allow the protocol driver to determine the MAC address corresponding to a particular IP address. If the table is empty, the MAC address is determined by sending an Ethernet broadcast packet to all devices on the local network asking the device with the desired IP address to answer with its MAC address. In this way, the table entry can be filled in. If no device answers, then the device is nonexistent or inoperative, and the packet cannot be sent. Some IP address ranges are reserved for use on internal networks, and can be allocated freely as long as no two internal hosts have the same IP address. These internal IP addresses are not routed to the Internet, and any internal hosts using one of these reserved IP addresses cannot communicate on the external Internet without being connected to a host that has a valid Internet IP address. The host would either translate the data, or it would act as a proxy. Each RCM3305/RCM3315 RabbitCore module has its own unique MAC address, which consists of the prefix 0090C2 followed by a code that is unique to each RCM3305/ RCM3315 module. For example, a MAC address might be 0090C2C002C0. TIP: You can always obtain the MAC address on your board by running the sample program DISPLAY_MAC.C from the SAMPLES\TCPIP folder. 54 RabbitCore RCM3305/RCM3315 6.2.3 Dynamically Assigned Internet Addresses In many instances, devices on a network do not have fixed IP addresses. This is the case when, for example, you are assigned an IP address dynamically by your dial-up Internet service provider (ISP) or when you have a device that provides your IP addresses using the Dynamic Host Configuration Protocol (DHCP). The RCM3305/RCM3315 modules can use such IP addresses to send and receive packets on the Internet, but you must take into account that this IP address may only be valid for the duration of the call or for a period of time, and could be a private IP address that is not directly accessible to others on the Internet. These addresses can be used to perform some Internet tasks such as sending e-mail or browsing the Web, but it is more difficult to participate in conversations that originate elsewhere on the Internet. If you want to find out this dynamically assigned IP address, under Windows 98 you can run the winipcfg program while you are connected and look at the interface used to connect to the Internet. Many networks use IP addresses that are assigned using DHCP. When your computer comes up, and periodically after that, it requests its networking information from a DHCP server. The DHCP server may try to give you the same address each time, but a fixed IP address is usually not guaranteed. If you are not concerned about accessing the RCM3305/RCM3315 from the Internet, you can place the RCM3305/RCM3315 on the internal network using an IP address assigned either statically or through DHCP. User’s Manual 55 6.3 Placing Your Device on the Network In many corporate settings, users are isolated from the Internet by a firewall and/or a proxy server. These devices attempt to secure the company from unauthorized network traffic, and usually work by disallowing traffic that did not originate from inside the network. If you want users on the Internet to communicate with your RCM3305/RCM3315, you have several options. You can either place the RCM3305/RCM3315 directly on the Internet with a real Internet address or place it behind the firewall. If you place the RCM3305/RCM3315 behind the firewall, you need to configure the firewall to translate and forward packets from the Internet to the RCM3305/RCM3315. 56 RabbitCore RCM3305/RCM3315 6.4 Running TCP/IP Sample Programs We have provided a number of sample programs demonstrating various uses of TCP/IP for networking embedded systems. These programs require you to connect your PC and the RCM3305/RCM3315 board together on the same network. This network can be a local private network (preferred for initial experimentation and debugging), or a connection via the Internet. RCM3305/RCM3315 System User’s PC Ethernet crossover cable Direct Connection (network of 2 computers) User’s Manual RCM3305/RCM3315 System Ethernet cables Hub To additional network elements Direct Connection Using a Hub 57 6.4.1 How to Set IP Addresses in the Sample Programs With the introduction of Dynamic C 7.30 we have taken steps to make it easier to run many of our sample programs. You will see a TCPCONFIG macro. This macro tells Dynamic C to select your configuration from a list of default configurations. You will have three choices when you encounter a sample program with the TCPCONFIG macro. 1. You can replace the TCPCONFIG macro with individual MY_IP_ADDRESS, MY_NETMASK, MY_GATEWAY, and MY_NAMESERVER macros in each program. 2. You can leave TCPCONFIG at the usual default of 1, which will set the IP configurations to 10.10.6.100, the netmask to 255.255.255.0, and the nameserver and gateway to 10.10.6.1. If you would like to change the default values, for example, to use an IP address of 10.1.1.2 for the RCM3305/RCM3315 board, and 10.1.1.1 for your PC, you can edit the values in the section that directly follows the “General Configuration” comment in the TCP_CONFIG.LIB library. You will find this library in the LIB\TCPIP directory. 3. You can create a CUSTOM_CONFIG.LIB library and use a TCPCONFIG value greater than 100. Instructions for doing this are at the beginning of the TCP_CONFIG.LIB library in the LIB\TCPIP directory. There are some other “standard” configurations for TCPCONFIG that let you select different features such as DHCP. Their values are documented at the top of the TCP_CONFIG.LIB library in the LIB\TCPIP directory. More information is available in the Dynamic C TCP/IP User’s Manual. 58 RabbitCore RCM3305/RCM3315 6.4.2 How to Set Up your Computer for Direct Connect Follow these instructions to set up your PC or notebook. Check with your administrator if you are unable to change the settings as described here since you may need administrator privileges. The instructions are specifically for Windows 2000, but the interface is similar for other versions of Windows. TIP: If you are using a PC that is already on a network, you will disconnect the PC from that network to run these sample programs. Write down the existing settings before changing them to facilitate restoring them when you are finished with the sample programs and reconnect your PC to the network. 1. Go to the control panel (Start > Settings > Control Panel), and then double-click the Network icon. 2. Select the network interface card used for the Ethernet interface you intend to use (e.g., TCP/IP Xircom Credit Card Network Adapter) and click on the “Properties” button. Depending on which version of Windows your PC is running, you may have to select the “Local Area Connection” first, and then click on the “Properties” button to bring up the Ethernet interface dialog. Then “Configure” your interface card for a “10Base-T Half-Duplex” or an “Auto-Negotiation” connection on the “Advanced” tab. NOTE: Your network interface card will likely have a different name. 3. Now select the IP Address tab, and check Specify an IP Address, or select TCP/IP and click on “Properties” to assign an IP address to your computer (this will disable “obtain an IP address automatically”): IP Address : 10.10.6.101 Netmask : 255.255.255.0 Default gateway : 10.10.6.1 4. Click or to exit the various dialog boxes. RCM3305/RCM3315 System IP 10.10.6.101 Netmask 255.255.255.0 User’s PC Ethernet crossover cable Direct Connection PC to RCM3305/RCM3315 Board User’s Manual 59 6.5 Run the PINGME.C Sample Program Connect the crossover cable from your computer’s Ethernet port to the RCM3305/ RCM3315 board’s RJ-45 Ethernet connector. Open this sample program from the SAMPLES\TCPIP\ICMP folder, compile the program, and start it running under Dynamic C. The crossover cable is connected from your computer’s Ethernet adapter to the RCM3305/ RCM3315 board’s RJ-45 Ethernet connector. When the program starts running, the green LINK light on the RCM3305/RCM3315 module should be on to indicate an Ethernet connection is made. (Note: If the LNK light does not light, you may not be using a crossover cable, or if you are using a hub perhaps the power is off on the hub.) The next step is to ping the board from your PC. This can be done by bringing up the MSDOS window and running the pingme program: ping 10.10.6.101 or by Start > Run and typing the entry ping 10.10.6.101 Notice that the yellow ACT light flashes on the RCM3305/RCM3315 module while the ping is taking place, and indicates the transfer of data. The ping routine will ping the board four times and write a summary message on the screen describing the operation. 6.6 Running Additional Sample Programs With Direct Connect The following sample programs are in the Dynamic C SAMPLES\RCM3300\TCPIP\ folder. • BROWSELED.C—This program demonstrates a basic controller running a Web page. Two “device LEDs” are created along with two buttons to toggle them. Users can use their Web browser to change the status of the lights. The DS3 and DS4 LEDs on the Prototyping Board will match those on the Web page. As long as you have not modified the TCPCONFIG 1 macro in the sample program, enter the following server address in your Web browser to bring up the Web page served by the sample program. http://10.10.6.100 Otherwise use the TCP/IP settings you entered in the TCP_CONFIG.LIB library. • MBOXDEMO.C—The optional LCD/keypad module (see Appendix C) must be plugged in to the Prototyping Board when using this sample program. This program demonstrates sending e-mail messages that are then shown on the LCD/keypad module display. The keypad is used to scroll through a menu to view the messages, flip to other messages, mark messages as read, and delete messages. When a new e-mail arrives, an LED on the LCD/keypad module turns on, and then turns off once the message has been marked as read. A log of all e-mail actions is kept, and can be displayed in the Web browser. All current e-mails can also be read with the Web browser. • PINGLED.C—This program demonstrates ICMP by pinging a remote host. It will flash LEDs DS3 and DS4 on the Prototyping Board when a ping is sent and received. 60 RabbitCore RCM3305/RCM3315 • SMTP.C—This program demonstrates using the SMTP library to send an e-mail when the S2 and S3 switches on the Prototyping Board are pressed. LEDs DS3 and DS4 on the Prototyping Board will light up when e-mail is being sent. 6.6.1 RabbitWeb Sample Programs You will need to have the Dynamic C RabbitWeb module installed before you run the sample programs described in this section. The following sample programs are in the Dynamic C SAMPLES\RCM3300\TCPIP\RABBITWEB folder. • BLINKLEDS.C—This program demonstrates a basic example to change the rate at which the DS3 and DS4 LEDs on the Prototyping Board blink. • DOORMONITOR.C—The optional LCD/keypad module (see Appendix C) must be plugged in to the Prototyping Board when using this sample program. This program demonstrates adding and monitoring passwords entered via the LCD/keypad module. • SPRINKLER.C—This program demonstrates how to schedule times for the relay and digital outputs in a 24-hour period. 6.6.2 Remote Application Update The following programs that make up the featured application for the RCM3305/ RCM3315 can be found in the SAMPLES\RCM3300\RemoteApplicationUpdate folder. • DLP_STATIC.C—This program uses the TCP/IP HTTP.LIB library, and outputs a basic static Web page. • DLP_WEB.C—This program outlines a basic download program with a Web interface. Complete information on the use of these programs is provided in the Remote Application Update instructions, which are available with the online documentation. 6.6.3 Dynamic C FAT File System, RabbitWeb, and SSL Modules The Dynamic C FAT File System, RabbitWeb, and Secure Sockets Layer (SSL) modules have been integrated into a sample program for the RCM3305 and the RCM3315. The sample program requires that you have installed the Dynamic C FAT File System, RabbitWeb, and SSL modules. TIP: Before running any of the sample programs described in this section, you should look at and run sample programs for the TCP/IP ZSERVER.LIB library, the FAT file system, RabbitWeb, SSL, the download manager, and HTTP upload to become more familiar with their operation. The INTEGRATION.C sample program in the SAMPLES\RCM3300\Module_Integration folder demonstrates the use of the TCP/IP ZSERVER.LIB library and FAT file system functionality with RabbitWeb dynamic HTML content, all secured using SSL. The sample program also supports dynamic updates of both the application and its resources using the Rabbit Download Manager (DLM) and HTTP upload capability, respectively— note that neither of these currently supports SSL security. User’s Manual 61 First, you need to format and partition the serial flash. Find the FMT_DEVICE.C sample program in the Dynamic C SAMPLES\FileSystem folder. Open this sample program with the File > Open menu, then compile and run it by pressing F9. FMT_DEVICE.C formats the mass storage device for use with the FAT file system. If the serial flash or NAND flash is already formatted, FMT_DEVICE.C gives you the option of erasing the mass storage flash and reformatting it with a single large partition. This erasure does not check for non-FAT partitions and will destroy all existing partitions. Next, run the INTEGRATION_FAT_SETUP.C sample program in the Dynamic C SAMPLES\RCM3300\Module_Integration folder. Open this sample program with the File > Open menu, then compile and run it by pressing F9. INTEGRATION_FAT_ SETUP.C will copy some #ximported files into the FAT file system. The last step to complete before you can run the INTEGRATION.C sample program is to create an SSL certificate. The SSL walkthrough in the online documentation for the Dynamic C SSL module explains how to do this. Now you are ready to run the INTEGRATION.C sample program in the Dynamic C SAMPLES\RCM3300\Module_Integration folder. Open this sample program with the File > Open menu, then compile and run it by pressing F9. NOTE: Since HTTP upload and the Dynamic C SSL module currently do not work together, compiling the INTEGRATION.C sample program will generate a serious warning. Ignore the warning because we are not using HTTP upload over SSL. A macro (HTTP_UPLOAD_SSL_SUPRESS_WARNING) is available to suppress the warning message. Open a Web browser, and browse to the device using the IP address from the TCP_ CONFIG.LIB library or the URL you assigned to the device. The humidity monitor will be displayed in your Web browser. This page is accessible via plain HTTP or over SSLsecured HTTPS. Click on the administrator link to bring up the admin page, which is secured automatically using SSL with a user name and a password. Use myadmin for user name and use myadmin for the password. The admin page demonstrates some RabbitWeb capabilities and provides access to the HTTP upload page. Click the upload link to bring up the HTTP upload page, which allows you to choose new files for both the humidity monitor and the admin page. If your browser prompts you again for your user name and password, they are the same as above. Note that the upload page is a static page included in the program flash, and can only be updated by recompiling and downloading the application. This page is protected so that you cannot accidentally change the upload page, possibly restricting yourself from performing future updates. To try out the update capability, click the upload link on the admin page and choose a simple text file to replace monitor.ztm. Open another browser window and load the main page. You will see that your text file has replaced the humidity monitor. To restore the monitor, go back to the other window, click back to go to the upload page again, and choose HUMIDITY_MONITOR.ZHTML to replace monitor.ztm and click Upload. 62 RabbitCore RCM3305/RCM3315 When you refresh the page in your browser, you will see that the page has been restored. You have successfully updated and restored your application's files remotely! When you are finished with the INTEGRATION.C sample program, you need to follow a special shutdown procedure before powering off to prevent any possible corruption of the FAT file system. Press and hold switch S2 on the Prototyping Board until LED DS3 blinks rapidly to indicate that it is now safe to turn the RCM3305/RCM3315 off. This procedure can be modified by the user to provide other application-specific shutdown tasks. 6.7 Where Do I Go From Here?

When the spectrum spreader is enabled with the clock doubler, every other clock cycle is shortened (sometimes lengthened) by a maximum amount given in the table above. The shortening takes place by shortening the high part of the clock. If the doubler is not enabled, then every clock is shortened during the low part of the clock period. The maximum shortening for a pair of clocks combined is shown in the table.

PROTOTYPING BOARD Appendix B describes the features and accessories of the Prototyping Board. User’s Manual 79 B.1 Introduction The Prototyping Board included in the Development Kit makes it easy to connect an RCM3305/RCM3315 module to a power supply and a PC workstation for development. It also provides some basic I/O peripherals (RS-232, RS-485, a relay, LEDs, and switches), as well as a prototyping area for more advanced hardware development. For the most basic level of evaluation and development, the Prototyping Board can be used without modification. As you progress to more sophisticated experimentation and hardware development, modifications and additions can be made to the board without modifying or damaging the RCM3305/RCM3315 module itself. The Prototyping Board is shown below in Figure B-1, with its main features identified.

Prototyping Board 80 RabbitCore RCM3305/RCM3315 B.1.1 Prototyping Board Features • Power Connection—A power-supply jack and a 3-pin header are provided for connection to the power supply. Note that the 3-pin header is symmetrical, with both outer pins connected to ground and the center pin connected to the raw V+ input. The cable of the AC adapter provided with the North American version of the Development Kit ends in a plug that connects to the power-supply jack (J1). A header plug leading to bare leads is provided for overseas customers to connect their power supply to the 3-pin header (J2)—the center pin of J2 is always connected to the positive terminal, and either edge pin is negative. Users providing their own power supply should ensure that it delivers 8–30 V DC at 1 A. • Regulated Power Supply—The raw DC voltage provided at the POWER IN jack is routed to a 5 V switching voltage regulator, then to a separate 3.3 V linear regulator. The regulators provide stable power to the RCM3305/RCM3315 module and the Prototyping Board. The voltage regulators will get warm while in use. • Power LED—The power LED lights whenever power is connected to the Prototyping Board. • Core LED—The core LED lights whenever an RCM3305/RCM3315 module is plugged in correctly on the Prototyping Board and the RCM3305/RCM3315 module is not being reset. • Relay LED—The relay LED lights whenever the Prototyping Board relay is energized. • Reset Switch—A momentary-contact, normally open switch is connected directly to the RCM3305/RCM3315’s /RESET_IN pin. Pressing the switch forces a hardware reset of the system. • I/O Switches and LEDs—Two momentary-contact, normally open switches are connected to the PG0 and PG1 pins of the RCM3305/RCM3315 module and may be read as inputs by sample applications. Four user LEDs (DS3–DS6) are connected to alternate I/O bus pins PA0–PA3 pins of the RCM3305/RCM3315 module via U8, and may be driven as output indicators. PE7 and PG5 control the registers in U8 as shown in the sample applications. • Prototyping Area—A generous prototyping area has been provided for the installation of through-hole components. +3.3 V, +5 V, and Ground buses run along one edge of this area. Several areas for surface-mount devices are also available. Each SMT pad is connected to a hole designed to accept a 30 AWG solid wire. • LCD/Keypad Module—Rabbit’s LCD/keypad module may be plugged in directly to headers LCD1JA, LCD1JB, and LCD1JC. The signals on headers LCD1JB and LCD1JC will be available only if the LCD/keypad module is plugged in to header LCD1JA. Appendix C provides complete information for mounting and using the LCD/keypad module. User’s Manual 81 • Module Extension Headers—The complete pin set of the RCM3305/RCM3315 module is duplicated at headers J8 and J9. Developers can solder wires directly into the appropriate holes, or, for more flexible development, 2 × 17 header strips with a 0.1" pitch can be soldered into place. See Figure B-4 for the header pinouts. • Digital I/O—Four digital inputs are available on screw-terminal header J6. See Figure B-4 for the header pinouts. • RS-232—Two 3-wire serial ports or one 5-wire RS-232 serial port are available on the Prototyping Board at screw-terminal header J14. • RS-485—One RS-485 serial port is available on the Prototyping Board at screw-terminal header J14. • Quadrature Decoder—Four quadrature decoder inputs (PF0–PF3) from the Rabbit 3000 chip are available on screw-terminal header J5. See Figure B-4 for the header pinouts. • H-Bridge Motor Driver—Two pairs of H-bridge motor drivers are supported using screw-terminal headers J3 and J4 on the Prototyping Board for stepper-motor control. See Figure B-4 for the header pinouts. • RabbitNet Port—One RS-422 RabbitNet port (shared with the serial flash interface) is available to allow RabbitNet peripheral cards to be used with the Prototyping Board. • Serial Flash Interface—One serial flash interface (shared with the RabbitNet port) is available to allow Rabbit’s SF1000 series serial flash to be used on the Prototyping Board. 82 RabbitCore RCM3305/RCM3315 B.2 Mechanical Dimensions and Layout C7 R62 R59 R54 R51 R3 R4 R5 R6 R7 R2 R63 R64 R65 R66 R55 R56 R57 R58 R10 OUT JP4 RP1 RP2 J11 BT1 Battery C13 U4 U5 R16 SERIAL FLASH/ MODEM J10 OUT 00 01 02 03 04 05 06 07 R20 /RES_OUT C5 R19 PB0 R9 R14 RABBITNET R8 U6 C6 U3 L293D H-DRIVER C4 U7 R18 PB2 C8 PF0_QD R60 R61 C14 C15 PB3 R67 R68 R69 R70 U2 R17 PB4 C12 PB6 C9 PF5 PB5 R13 U1 R12 PB7 PF7 L293D H-DRIVER C10 C11 PE5 PE6 PF4 PF6 PE7 PE4 D2 L1 R11 PE3 JP1 PE0 PE1 C3 JP2 PG6 PG7 J3 PG5 C2 R52 R53 JP3 GND +DC GND J1 J2 PG4 DS1 +DC J4 VMB– MDB1 MDB2 MDB3 MDB4 VMB+ VMA+ MDA1 MDA2 MDA3 MDA4 VMA– POWER /IORD +5V QD2A QD2B QD1A QD1B GND J5 SM0 +5V SMODE1 /IOWR PF0_CLKD C1 /RES IN0 VRAM IN1 +3.3 V VBT IN2 GND GND IN3 D1 NC J6 R1 J8 GND J7 GND Figure B-2 shows the mechanical dimensions and layout for the Prototyping Board.

Depending on the amount of current required by the application, different regulators can be used to supply this voltage. The Prototyping Board has an onboard +5 V switching power regulator from which a +3.3 V linear regulator draws its supply. Thus both +5 V and +3.3 V are available on the Prototyping Board. The Prototyping Board itself is protected against reverse polarity by a diode at D1 as shown in Figure B-3.

Prototyping Board Pinout 86 RabbitCore RCM3305/RCM3315 The Prototyping Board comes with the basic components necessary to demonstrate the operation of the RCM3305/RCM3315. Four user LEDs (DS3–DS6) are connected to alternate I/O bus pins PA0–PA3 pins of the RCM3305/RCM3315 module via U8, and may be driven as output indicators when controlled by PE7 and PG5 as shown in the sample applications. Two switches (S2 and S3) are connected to PG0 and PG1 to demonstrate the interface to the Rabbit 3000 microprocessor. Reset switch S1 is the hardware reset for the RCM3305/RCM3315. The Prototyping Board provides the user with RCM3305/RCM3315 connection points brought out conveniently to labeled points at J8 and J9 on the Prototyping Board. Although locations J8 and J9 are unstuffed, 2 × 17 headers are included in the bag of parts. RS-232 and RS-485 signals are available on screw-terminal header J14, quadrature decoder inputs are available on screw-terminal header J5, and digital inputs are available on screwterminal header J6. A 1 × 5 header strip from the bag of parts may be installed at J12 for four sinking digital outputs. The clocked Serial Port B signals from the RCM3305/RCM3315 are used for the serial flash, and cannot be accessed via header J13 on the Prototyping Board. If you don’t plan to use the LCD/keypad module, additional signals may be brought out on 1 × 5 and 1 × 8 headers from the bag of parts that you install at J15 and J16. If you don’t plan to use the stepper-motor control option, additional CMOS outputs are available via a 1 × 8 header that you install at J10. There is a through-hole prototyping space available on the Prototyping Board. The holes in the prototyping area are spaced at 0.1" (2.5 mm). +3.3 V, +5 V, and GND traces run along one edges of the prototyping area. Small to medium circuits can be prototyped using pointto-point wiring with 20 to 30 AWG wire between the prototyping area, the +3.3 V, +5 V, and GND traces, and the surrounding area where surface-mount components may be installed. Small holes are provided around the surface-mounted components that may be installed around the prototyping area. B.4.1 Adding Other Components There are two sets of pads for 6-pin, 16-pin, and 28-pin devices that can be used for surface-mount prototyping devices. There are also pads that can be used for SMT resistors and capacitors in an 0805 SMT package. Each component has every one of its pin pads connected to a hole in which a 30 AWG wire can be soldered (standard wire wrap wire can be soldered in for point-to-point wiring on the Prototyping Board). Because the traces are very thin, carefully determine which set of holes is connected to which surface-mount pad. User’s Manual 87 B.4.2 Digital I/O B.4.2.1 Digital Inputs The Prototyping Board has four digital inputs, IN0–IN3, each of which is protected over a range of –36 V to +36 V. The inputs are pulled up to +3.3 V as shown in Figure B-5. JP6 +3.3 V 27 kW ® 22 kW GND Figure B-5. Prototyping Board Digital Inputs The four quadrature decoder inputs on screw-terminal header J5 may be used as inputs IN4–IN7. To use the PF0 signal from the Rabbit microprocessor, which goes to QD1B, remember to reconfigure the jumper on header JP3 to jumper pins 1–2. The actual switching threshold is between 0.9 V and 2.3 V. Anything below this value is a logic 0, and anything above is a logic 1. The digital inputs are each fully protected over a range of -36 V to +36 V, and can handle short spikes of ±40 V. 88 RabbitCore RCM3305/RCM3315 B.4.3 CMOS Digital Outputs If the stepper-motor option is not used, eight CMOS-level digital outputs are available at J10, and can each handle up to 25 mA. B.4.4 Sinking Digital Outputs Four sinking digital outputs shared with LEDs DS3–DS6 are available at J12, and can each handle up to 500 mA. Figure B-6 shows a wiring diagram for a typical sinking output. Vcc ADD DIODE WHEN LOAD IS INDUCTIVE 330 W 1 kW Figure B-6.

User’s Manual 89 B.4.6 Serial Communication The Prototyping Board allows you to access four of the serial ports from the RCM3305/ RCM3315 module. Table B-2 summarizes the configuration options. Table B-2. Prototyping Board Serial Port Configurations Serial Port Signal Header Configured via Default Use Alternate Use C J14 JP5* RS-485 — RabbitNet (PD2 = 1) J7 D JP3 SF1000 (PD2 = 0) J11 Rabbit 3000 quadrature decoder E J14 — RS-232 — F J14 — RS-232 — * RS-485 termination and bias resistors are configured via header JP5. Serial Port D is configured in software either to allow J7 to be used as a RabbitNet port or to allow J11 to be used as a serial interface for the SF1000 series serial flash. 90 RabbitCore RCM3305/RCM3315 B.4.6.1 RS-232 RS-232 serial communication on the Prototyping Board is supported by an RS-232 transceiver installed at U9. This transceiver provides the voltage output, slew rate, and input voltage immunity required to meet the RS-232 serial communication protocol. Basically, the chip translates the Rabbit 3000’s signals to RS-232 signal levels. Note that the polarity is reversed in an RS-232 circuit so that a +5 V output becomes approximately -10 V and 0 V is output as +10 V. The RS-232 transceiver also provides the proper line loading for reliable communication. RS-232 can be used effectively at the RCM3305/RCM3315 module’s maximum baud rate for distances of up to 15 m. RS-232 flow control on an RS-232 port is initiated in software using the serXflowcontrolOn() function call from LIB\RS232.LIB, where X is the serial port (E or F). The locations of the flow control lines are specified using a set of five macros. SERX_RTS_PORT—Data register for the parallel port that the RTS line is on (e.g., PGDR). SERX_RTS_SHADOW—Shadow register for the RTS line's parallel port (e.g., PGDRShadow). SERX_RTS_BIT—The bit number for the RTS line. SERX_CTS_PORT—Data register for the parallel port that the CTS line is on (e.g., PCDRShadow). SERX_CTS_BIT—The bit number for the CTS line. Standard 3-wire RS-232 communication using Serial Ports E and F is illustrated in the following sample code. #define EINBUFSIZE 15 #define EOUTBUFSIZE 15 // set size of circular buffers in bytes #define FINBUFSIZE 15 #define FOUTBUFSIZE 15 #define MYBAUD 115200 #endif main(){ serEopen(_MYBAUD); serFopen(_MYBAUD); serEwrFlush(); serErdFlush(); serFwrFlush(); serFrdFlush(); serEclose(_MYBAUD); serFclose(_MYBAUD); } User’s Manual // set baud rate // open Serial Ports E and F // flush their input and transmit buffers // close Serial Ports C and D 91 B.4.6.2 RS-485 The Prototyping Board has one RS-485 serial channel, which is connected to the Rabbit 3000 Serial Port C through an RS-485 transceiver. The half-duplex communication uses an output from PD7 on the Rabbit 3000 to control the transmit enable on the communication line. Using this scheme a strict master/slave relationship must exist between devices to insure that no two devices attempt to drive the bus simultaneously. Serial Port C is configured in software for RS-485 as follows. #define #define #define #define #define #define ser485open serCopen ser485close serCclose ser485wrFlush serCwrFlush ser485rdFlush serCrdFlush ser485putc serCputc ser485getc serCgetc #define CINBUFSIZE 15 #define COUTBUFSIZE 15 #ifndef _485BAUD #define _485BAUD 115200 #endif The configuration shown above is based on circular buffers. RS-485 configuration may also be done using functions from the PACKET.LIB library.

RS-485 Termination and Bias Resistors For best performance, the termination resistors in a multidrop network should be enabled only on the end nodes of the network, but not on the intervening nodes. Jumpers on boards whose termination resistors are not enabled may be stored across pins 1–3 and 4–6 of header JP5. B.4.7 RabbitNet Ports The RJ-45 jack labeled RabbitNet is a clocked SPI RS-422 serial I/O expansion port for use with RabbitNet peripheral boards. The RabbitNet jack does not support Ethernet connections. Header JP3 must have pins 2–3 jumpered when using the RabbitNet port. The RabbitNet port is enabled in software by setting PD2 = 1. Note that the RabbitNet port and the J11 interface cannot be used simultaneously. User’s Manual 93 B.4.8 Other Prototyping Board Modules An optional LCD/keypad module is available that can be mounted on the Prototyping Board. The signals on headers LCD1JB and LCD1JC will be available only if the LCD/ keypad module is installed. Refer to Appendix C, “LCD/Keypad Module,” for complete information. Rabbit’s SF1000 series serial flash may be installed in the socket labeled J11. The J11 interface is enabled in software by setting PD2 = 0. Header JP3 must have pins 2–3 jumpered when using the J11 interface. Note that the RabbitNet port and the J11 interface cannot be used simultaneously. B.4.9 Quadrature Decoder Four quadrature decoder inputs are available on screw-terminal header J5. To use the PF0 input from the Rabbit microprocessor, which goes to the QD1B input, remember to reconfigure the jumper on header JP3 to jumper pins 1–2. Additional information on the use of the quadrature decoders on Parallel Port F is provided in the Rabbit 3000 Microprocessor User’s Manual. B.4.10 Stepper-Motor Control The Prototyping Board can be used to demonstrate the use of the RCM3305/RCM3315 to control a stepper motor. Stepper motor control typically directs moves in two orthogonal directions, and so two sets of stepper-motor control circuits are provided for via screwterminal headers J3 and J4.

POWER SUPPLY Appendix D provides information on the current requirements of the RCM3305/RCM3315, and includes some background on the reset generator. D.1 Power Supplies Power is supplied from the motherboard to which the RCM3305/RCM3315 is connected via header J4. The RCM3305/RCM3315 requires a regulated 3.15 V to 3.45 V DC power source. An RCM3305/RCM3315 with no loading at the outputs operating at 44.2 MHz typically draws 350 mA. D.1.1 Battery Backup The RCM3305/RCM3315 does not have a battery, but there is provision for a customersupplied battery to back up the data SRAM and keep the internal Rabbit 3000 real-time clock running. Header J4, shown in Figure D-1, allows access to the external battery. This header makes it possible to connect an external 3 V power supply. This allows the SRAM and the internal Rabbit 3000 real-time clock to retain data with the RCM3305/RCM3315 powered down. External Battery J4 VRAM 29 +3.3 VIN 31 30 VBAT_EXT 32 GND Figure D-1. External Battery Connections at Header J4 User’s Manual 135 A lithium battery with a nominal voltage of 3 V and a minimum capacity of 165 mA·h is recommended. A lithium battery is strongly recommended because of its nearly constant nominal voltage over most of its life. The drain on the battery by the RCM3305/RCM3315 is typically 6 µA when no other power is supplied. If a 165 mA·h battery is used, the battery can last about 3 years: 165 mA·h ------------------------ = 3.1 years. 6 µA The RCM3305/RCM3315 does not drain the battery while it is powered up normally. Cycle the main power off/on on the RCM3305/RCM3315 after you install a backup battery for the first time, and whenever you replace the battery. This step will minimize the current drawn by the real-time clock oscillator circuit from the backup battery should the RCM3305/RCM3315 experience a loss of main power. NOTE: Remember to cycle the main power off/on any time the RCM3305/RCM3315 is removed from the Protoyping Board or motherboard since that is where the backup battery would be located. Rabbit’s Technical Note TN235, External 32.768 kHz Oscillator Circuits, provides additional information about the current draw by the the real-time clock oscillator circuit. D.1.2 Battery-Backup Circuit Figure D-2 shows the battery-backup circuit. VOSC VRAM External Battery VBAT-EXT D1 R46 R3 R7 150 kW 100 W 47 kW C2 100 nF C5 10 nF Figure D-2. RCM33305/RCM3315 Backup Battery Circuit The battery-backup circuit serves three purposes: • It reduces the battery voltage to the SRAM and to the real-time clock, thereby limiting the current consumed by the real-time clock and lengthening the battery life. • It ensures that current can flow only out of the battery to prevent charging the battery. • A voltage, VOSC, is supplied to U1, which keeps the 32.768 kHz oscillator working when the voltage begins to drop. 136 RabbitCore RCM3305/RCM3315 D.1.3 Reset Generator The RCM3305/RCM3315 uses a reset generator to reset the Rabbit 3000 microprocessor when the voltage drops below the voltage necessary for reliable operation. The reset occurs between 2.85 V and 3.00 V, typically 2.93 V. The RCM3305/RCM3315 has a reset pin, pin 28 on header J4. This pin provides access to the reset input of the reset generator, whose output drives the reset input of the Rabbit 3000 and peripheral circuits. The /RESET output from the reset generator is available on pin 1 of header J4 on the RCM3305/RCM3315, and can be used to reset user-defined circuits on the motherboard on which the RCM3305/RCM3315 module is mounted.

RABBITNET E.1 General RabbitNet Description RabbitNet is a high-speed synchronous protocol developed by Rabbit to connect peripheral cards to a master and to allow them to communicate with each other. E.1.1 RabbitNet Connections All RabbitNet connections are made point to point. A RabbitNet master port can only be connected directly to a peripheral card, and the number of peripheral cards is limited by the number of available RabbitNet ports on the master. SLAVE Straight-through Ethernet cable SLAVE Rabbit 3000® Microprocessor MASTER Crossover Ethernet cable MASTER SLAVE Straight-through Ethernet cable Figure E-1. Connecting Peripheral Cards to a Master User’s Manual 139 Use a straight-through Ethernet cable to connect the master to slave peripheral cards, unless you are using a device such as the OP7200 that could be used either as a master or a slave. In this case you would use a crossover cable to connect an OP7200 that is being used as a slave. Distances between a master unit and peripheral cards can be up to 10 m or 33 ft. E.1.2 RabbitNet Peripheral Cards • Digital I/O 24 inputs, 16 push/pull outputs, 4 channels of 10-bit A/D conversion with ranges of 0 to 10 V, 0 to 1 V, and -0.25 to +0.25 V. The following connectors are used: Signal = 0.1" friction-lock connectors Power = 0.156" friction-lock connectors RabbitNet = RJ-45 connector • A/D converter 8 channels of programmable-gain 12-bit A/D conversion, configurable as current measurement and differential-input pairs. 2.5 V reference voltage is available on the connector. The following connectors are used: Signal = 0.1" friction-lock connectors Power = 0.156" friction-lock connectors RabbitNet = RJ-45 connector • D/A converter 8 channels of 0–10 V 12-bit D/A conversion. The following connectors are used: Signal = 0.1" friction-lock connectors Power = 0.156" friction-lock connectors RabbitNet = RJ-45 connector • Display/Keypad interface allows you to connect your own keypad with up to 64 keys and one character liquid crystal display from 1 × 8 to 4 × 40 characters with or without backlight using standard 1 × 16 or 2 × 8 connectors. The following connectors are used: Signal = 0.1" headers or sockets Power = 0.156" friction-lock connectors RabbitNet = RJ-45 connector • Relay card 6 relays rated at 250 V AC, 1200 V·A or 100 V DC up to 240 W. The following connectors are used: Relay contacts = screw-terminal connectors Power = 0.156" friction-lock connectors RabbitNet = RJ-45 connector Visit our Web site for up-to-date information about additional cards and features as they become available. The Web site also has the latest revision of this user’s manual. 140 RabbitCore RCM3305/RCM3315 E.2 Physical Implementation There are four signaling functions associated with a RabbitNet connection. From the master’s point of view, the transmit function carries information and commands to the peripheral card. The receive function is used to read back information sent to the master by the peripheral card. A clock is used to synchronize data going between the two devices at high speed. The master is the source of this clock. A slave select (SS) function originates at the master, and when detected by a peripheral card causes it to become selected and respond to commands received from the master. The signals themselves are differential RS-422, which are series-terminated at the source. With this type of termination, the maximum frequency is limited by the round-trip delay time of the cable. Although a peripheral card could theoretically be up to 45 m (150 ft) from the master for a data rate of 1 MHz, Rabbit recommends a practical limit of 10 m (33 ft). Connections between peripheral cards and masters are done using standard 8-conductor Ethernet cables. Masters and peripheral cards are equipped with RJ-45 8-pin female connectors. The cables may be swapped end for end without affecting functionality. E.2.1 Control and Routing Control starts at the master when the master asserts the slave select signal (SS). Then it simultaneously sends a serial command and clock. The first byte of a command contains the address of the peripheral card if more than one peripheral card is connected. A peripheral card assumes it is selected as soon as it receives the select signal. For direct master-to-peripheral-card connections, this is as soon as the master asserts the select signal. The connection is established once the select signal reaches the addressed slave. At this point communication between the master and the selected peripheral card is established, and data can flow in both directions simultaneously. The connection is maintained so long as the master asserts the select signal.
