Development Board Hardware 4.1 INTRODUCTION This chapter provides a more detailed description of the hardware on the PIC24FJ256DA210 Development Board, and the procedures on configuring its many features. Topics covered include: • Functional Overview • General Hardware Features • Setup and Configuration 4.2 FUNCTIONAL OVERVIEW The development board is centered on the PIC24FJ256DA210 microcontroller which integrates in a single package a graphic controller, a CTMU for touch-sensing applications, and a wide range of other peripherals. The microcontroller’s Graphics module is capable of driving TFT, CSTN and MSTN displays in a number of sizes and color depths. Many display applications (up to 8 bpp in QVGA) can be run from the microcontroller’s 96 KByte RAM buffer. For bigger displays or higher color resolution, the microcontroller can directly interface with external RAM devices for additional data storage. For non-volatile data storage, both serial and parallel Flash memory devices are provided. The built-in USB functionality can be configured to operate in Device mode, as a stand-alone USB host, or as a USB On-The-Go (OTG) device. Host and OTG modes can be additionally configured for different types of bus sensing and external regulator support. Push buttons, CTMU touch sensors and a potentiometer are provided for a variety of user-defined inputs. These share three common I/Os on the microcontroller, along with three LEDs, and are configured manually with jumpers. A PICtail Plus edge connector is provided, allowing the development board to be used with different compatible PICtail Plus daughter board. An RS-232 port is provided for general purpose serial communications between the development board and a host PC; this serial port can also be re-configured to be available through the PICtail Plus connector. Figure 4-1 shows the main components of the development board.  2010 Microchip Technology Inc. DS51911A-page 31 PIC24FJ256DA210 Development Board User’s Guide FIGURE 4-1: PIC24FJ256DA210 DEVELOPMENT BOARD BLOCK DIAGRAM Display Panel (TFT, CSTN, MSTN) Resistive Touch Screen Display SPI DISPLAY Connector 512 KByte SRAM SPI FLASH (16MBit) SPI 512 Kbyte FLASH USB Host USB Device PICtail™ Plus Connector EPMP PIC24FJ256DA210 UART RS-232 Transceiver USB ICSP™ OTG USB 4.3 3 CTMU/ 4 LEDs 3 Buttons/ Switches R3 Potentiometer GENERAL HARDWARE FEATURES 4.3.1 PCB Layout The PIC24FJ256DA210 Development Board uses several design strategies to provide a stable demonstration and development environment. Users should note these features and design tips when developing their own graphic applications. The development board uses a four-layer PCB design; this allows high-frequency signals to be routed in a way to avoid crosstalk between data signals. It also gives additional noise protection due to improved grounding. For additional noise protection, oscillator circuits and crystals are laid out with appropriate grounding and guard rings. The layout guidelines are described in Section 2. “Guidelines for Getting Started with 16-Bit Microcontrollers” of the device data sheet. Each group of color signals (Red, Green and Blue) is routed together to reduce intercolor crosstalk. This means, for example, that Red signals are close together and do not mix with Green and/or Blue signals. Ideally, it is recommended to run a ground wire or trace between groups of color signals to reduce crosstalk. Also, the traces for color data should be as close to equal length as possible, and avoid the use of vias wherever possible. 4.3.2 Microcontroller The development board is supplied with the PIC24FJ256DA210 microcontroller directly soldered to the board at U2. The device is installed with the notched corner (pin 1) oriented to the lower right. Vias are provided around the device, which allow access to all microcontroller signals; this is labelled on the board as U9. A riser may be installed here to facilitate connections to user added components in the prototyping area. DS51911A-page 32  2010 Microchip Technology Inc. Development Board Hardware 4.3.3 Oscillator Options The PIC24FJ256DA210 Development Board is equipped with two separate oscillator circuits. The main oscillator uses an 8 MHz crystal (Y1) and functions as the controller’s primary oscillator. A second oscillator is implemented using a discrete oscillator circuit with a 32.768 kHz (watch type) crystal (Y2). This is connected to the microcontroller’s SCLKI pin, providing an external clock source for the secondary oscillator option used to clock the RTCC and Timer1 modules. A discrete oscillator is used in this application to free up an additional pin for general I/O use. To use this clock source, the microcontroller must be configured to use External Clock mode for the secondary oscillator. For additional information on secondary oscillator configuration, refer to the “PIC24FJ256DA210 Family Data Sheet” (DS39969). 4.3.4 Power Supply The PIC24FJ256DA210 Development Board supports two power options. In the first, an unregulated DC supply of 9V to 15V is supplied to J1. (A power supply is not provided with the development board, unless the kit was purchased. If one is required, Microchip Part number AC162039 is recommended). The 5V and 3.3V regulators (Q1 and Q2, respectively) provide stable power to the board, as well as compatible display daughter boards. Regulated 3.3V voltage is derived from the 5V regulated voltage. Optionally, an external, regulated DC power supply can be used to provide power to the board. Two separate voltages are required: +5V (to TP3, the red terminal near the upper left corner, adjacent to J9) and +3.3V (to TP4, the yellow terminal near the upper right corner, adjacent to the prototype area). The on-board voltage regulators can deliver a total combined current of 800 mA. If a larger display with a current rating higher than 800 mA (combined board and display rating) is to be used, the display board must be independently powered. In these cases, power to the display cannot be provided through display connector V1. Only common ground between the development board and the larger display should be connected through V1. A green power-on LED (D6) indicates when power is applied to the board from either source. The power-on LED indicates the presence of +3.3V. 4.3.5 Programming and Debugging Interface The PIC24FJ256DA210 Development Board can be programmed using either the (PICkit) connector (J9) or the 5-wire, RJ-11 (ICD) connector (J10). Only one interface may be used at any given time. Use J9 to connect a PICkit 3 programmer, or other similar programmer/debugger devices, to program the development board. Use J10 to program the board using the MPLAB ICD 3 debugger or MPLAB REAL ICE in-circuit emulator. 4.3.6 Reset Switch (S4) Switch S4 is connected to the MCLR line of the microcontroller. When pressed, it pulls the MCLR pin low, resetting the microcontroller (and any application the microcontroller is running). The same reset signal is also connected to the Reset signals of the PICkit and ICD connectors. However, any applications being run on PICtail daughter cards installed in the PICtail Plus port will not be automatically reset. In these cases, the user must provide an alternate hardware signal to the daughter board.  2010 Microchip Technology Inc. DS51911A-page 33 PIC24FJ256DA210 Development Board User’s Guide 4.4 SETUP AND CONFIGURATION The PIC24FJ256DA210 Development Board has been designed with a wide range of hardware options. These allow the user to evaluate the entire range of the microcontroller’s features, include user-defined inputs, explore the range of graphics options, and incorporate USB connectivity options. To maintain flexibility, many of the board’s hardware options are configured using standard jumpers. In a few cases, modifying the board at several locations (by the addition or removal of resistors) may also be required. Details of the configuration options and how to select them are provided in the following sections. A list of the development board’s configuration jumpers is provided in Table 4-1; their corresponding locations are shown in Figure 4-2.

The number of inputs available depends on the daughter board and the application. See Section 4.4.6 “PICtail™ Plus Card Modular Expansion Connector” for additional information. LED outputs are shared with CTMU input channels. User-Defined Inputs and LEDs The PIC24FJ256DA210 Development Board implements a variety of user-defined inputs: push button switches, capacitance-sensing touch pads, a potentiometer, and four LEDs. The development board multiplexes the switches, touch sensors, potentiometer and three of the LEDs through three I/O pins (RB5, RE9 and RG8). For each of these pins, only one input mode can be chosen at any given time. The fourth LED (D4) shares a pin with an address line for the external memory devices. Note that the implementation of shared inputs and outputs used in the development board is not a recommended design practice. In this case, it is implemented in consideration of I/O pin constraints. Using separate pins for different input and output features is always recommended. If the CTMU touch sensors are enabled, the LEDs can be used simultaneously. However, care must be taken in the application to switch the I/O pins alternately as analog input and digital output as required. Please refer to the “PIC24FJ256DA210 Family Data Sheet” (DS39969) for details on configuring the I/O ports. The user-defined features are configured using jumpers J13, J14 and J15. In some cases, modifications to accompanying resistors are also required. The locations of the components are shown in Figure 4-3. A summary of the jumper settings is provided in Table 4-3.  2010 Microchip Technology Inc.

Although the particular operating mode of the microcontroller is determined by the application and device configuration, the development board hardware also needs to be configured to suit the mode as well. These are selected by the USB mode jumpers (Figure 4-4, callout 1). Additional current sense options for Host and OTG modes are configured with setting I/O jumpers and modifying certain on-board resistors (callouts 2 and 3). Note: Only one USB mode may be enabled in hardware at any time. FIGURE 4-4: CONFIGURING USB MODES 2 3 1 M 4.4.2.1 USB HOST MODE (DEFAULT) To enable the USB Host Mode: 1. Install jumper JP6. 2.

In USB OTG mode, use J7 (Type Micro AB Female USB connector) to connect with external USB OTG devices. Note: 4.4.3 Enabling USB OTG mode may require the remapping of the UART’s TX signal. See Section 4.4.3.1 “UART and USB OTG Mode (TX Remapping)” for more information. UART (RS-232) The development board provides one UART, with its RX and TX signals appearing on pins RD0 and RF3 of the PIC24FJ256DA210, respectively. The signals can be configured to appear at one of two places: • The RS-232 external serial port (default). • The PICtail Plus connector, as signals U1RX (pin 2) and U1TX (pin 4). An RS-232 level shifter (U3) has been provided with all necessary hardware to support the external serial port. The DB-9F serial connector (P1) is wired to support hardware flow control; however, the flow control signals are not connected to the microcontroller. The port is configured as a Data Communication Equipment (DCE) device. Note: The TX and RX signals are mapped to the microcontroller pins using the Peripheral Pin Select (PPS) feature. When developing applications, make sure that the pins are remapped properly to use the UART Receive and UART Transmit signals. Refer to Section 10.4 “Peripheral Pin Select” of the PIC24FJ256DA210 data sheet for a detailed discussion of PPS. The UART’s availability is configured by jumpers JP16 and JP17. Their location is shown in Figure 4-5. To access the UART through the RS-232 serial port: 1. Set jumper J16 to position 1-2 (USART_TX – TX) (default). 2. Set jumper J17 to position 1-2 (USART_RX – RX) (default). In this configuration, a host PC running the appropriate application can communicate with the development board using the serial channel. Use a standard (“straight-through”) serial cable connected to P1. To access the UART through the PICtail Plus expansion port: 1. Set jumper J16 to position 2-3 (U1TX – TX). 2. Set jumper J17 to position 2-3 (U1RX – RX). In this configuration, the U1RX and U1TX signals appear at pins 2 and 4 of the PICtail Plus connector, respectively.  2010 Microchip Technology Inc. DS51911A-page 39 PIC24FJ256DA210 Development Board User’s Guide FIGURE 4-5: UART CONFIGURATION M 4.4.3.1 UART AND USB OTG MODE (TX REMAPPING) Normally, the UART TX signal appears on pin RF3, along with the USBID signal. When USB OTG mode is enabled, USBID takes priority over the TX signal. If the UART is also needed, this requires the TX signal to be remapped to another pin. The development board allows for RG8, normally used for S1/PAD1/LED1, to function as the TX signal in these cases. In addition to remapping the pin in software using PPS, resistor R4, R5, R26 and R27 will also need to be changed (Figure 4-6). To remap the TX signal with USB OTG enabled: 1. If populated, remove resistor R4 (callout 1). Alternatively, remove jumper JP13 (callout 2). (Both disconnect the TX signal from pin RF3.) 2. Populate resistor R5 (callout 1) with a 0 resistor (connects USBID signal to pin RF3). 3. Populate resistor R27 with a 0 resistor (callout 2) (connects TX signal to pin RG8). 4. If populated, remove resistor R26 (callout 2) (disconnects Overcurrent Sense signal). FIGURE 4-6: REMAPPING THE UART TX SIGNAL 1 2 M DS51911A-page 40  2010 Microchip Technology Inc. Development Board Hardware 4.4.3.2 UART AND DISPLAY BACKLIGHT (RX SIGNAL) The UART’s RX signal is mapped to only one pin (RD0) of the microcontroller. This pin is also used by the development board to optionally control the backlight for the display daughter board; all functions are multiplexed through the same jumper, JP12. If either of the backlight control options is selected, the UART becomes unavailable to the external RS-232 port. 4.4.4 Graphics Port The PIC24FJ256DA210 Development Board can support TFT, MSTN and CSTN displays. Displays of 4, 8 and 16-bit data widths are supported. The 64-pin display Connector V1 (J3) (on the right hand side bottom corner of the board) is provided for connection of Microchip display boards. 4.4.4.1 TFT AND STN INTERFACES When developing applications using TFT displays and the Graphics Display Prototype Board, the 16-bit display bus can be used to send 16-bit RGB data (5-6-5 bits respectively) to a standard 24-bit (8-8-8) or 18-bit (6-6-6) RGB display. To do this, color data from the microcontroller is mapped to the Most Significant bits (MSbs) of the display. The Least Significant bit lines of the display (3-2-3 for 24-bit displays, 1-0-1 for 18-bit) are then tied to the MSb. This technique allows full brightness whenever the MSb is ‘1’, and full blackness when the MSb is ‘0’. The controller-to-display data mapping is detailed in Table 4-5. TABLE 4-5: RGB INTERFACE MAPPING FOR TFT DISPLAYS Graphics Data Pins (GDx) 18-Bit RGB Display (6-6-6) 24-Bit RGB Display (8-8-8) RED GD Red Red GD Red Red GD Green Green GD Green Green GD Blue Blue GD Blue Blue GREEN BLUE 4.4.4.2 STN INTERFACES The development board can directly interface with STN displays (both CSTN and MSTN) of 4, 8 or 16-bit data width. The mapping of graphics data to the display data input is described in Table 4-6. Configuration of the different data widths is done by the graphics controller module through the register interface. Refer to the “PIC24FJ256DA210 Family Data Sheet” (DS39969) for more information.

DS51911A-page 41 PIC24FJ256DA210 Development Board User’s Guide 4.4.4.3 RESISTIVE TOUCH SCREEN INTERFACE The development board supports display panels with a built-in 4-wire resistive touch screen. The resistive touch screen interface (X-, Y-, X+ and Y+) is used to directly connect to the touch screen signals. X+ and Y+ are both analog and digital signals, and are connected to I/O ports that can function both as analog inputs and digital outputs. X- and Y- are digital output signals only, and are connected to digital I/O ports. The X+ and Y- signals are multiplexed with the SPI based touch screen controller. When using the 4-wire resistive touch screen interface, jumpers JP9 and JP10 must be set to their default positions, bridging pins 1 and 2 (Figure 4-7, callout 1). 4.4.4.4 SPI TOUCH CONTROLLER INTERFACE Two SPI channels (two Chip Select lines) are provided in Display Connector V1 to support display panels equipped with the following: • SPI-Based Timing Controller: Some displays requires programming of an on-board Timing Controller (TCON) to initialize the settings of the display before it is used. The TCON is used to synchronize the display glass timing with the display controller signal timing. This option is provided on the pins A27 (SPI_SCK), A28 (SPI_MISO), B27 (DISP_SPI_CS) and B28 (SPI_MOSI) of display connector V1. • SPI-Based Touch Controller: In some cases, an SPI-based touch module is used with the display. Every time a touch is detected, it sends an interrupt to the host controller to inform the host that there is a fresh touch input and the information must be forwarded from the touch module to the host controller through SPI communications. The development board shares two of the pins of the 4-wire resistive touch screen with the interrupt and chip select line of the SPI based touch controller. The sharing is done this way since in any system, only one of the two types of user interface will be used. The SPI-based touch control features are configured by jumpers JP9 and JP10 (Figure 4-7, callout 1). To enable the use of an SPI-based touch controller, set jumpers JP9 and JP10 to bridge positions 2-3. Note: As of this writing, none of the Microchip display boards support SPI-based touch controllers. FIGURE 4-7: TOUCH CONTROLLER AND BACKLIGHT CONFIGURATION 2 1 M DS51911A-page 42  2010 Microchip Technology Inc. Development Board Hardware 4.4.4.5 BACKLIGHT CONTROL Depending on the display glass being used, backlight control is provided as an ON/OFF signal, or as a PWM pulse train for a continuous range of brightness. Jumper JP12 (Figure 4-7, callout 2) selects which signal is enabled on display connector V1. By default, backlight control is disconnected (position 2-4). • To enable BKLT_EN (ON/OFF), set JP12 to bridge 2-3. • To enable BKLT_PWM (PWM controlled contrast), set JP12 to bridge 1-2. Note: 4.4.5 If either of the backlight control modes is selected, access to the UART will be disabled. See Section 4.4.3.2 “UART and Display Backlight (RX Signal)” for more information. On-Board External Memory The PIC24FJ256DA210 can be used to create a graphics solution without any external memory resources. However, in cases where the application requires a higher color depth (8 bits per pixel or more), or larger storage for images and data, external SRAM and Flash memory devices are provided on the development board. Both SRAM and parallel Flash memory can be enabled at the same time. The Enhanced Parallel Master Port module (EPMP) accesses memory on both devices with the same data and address lines. PMCS1 is used as the Chip Select signal for the SRAM, and PMCS2 is used for the parallel Flash. Note, however, that configuring a memory addressing size option for one device selects the same size for the other. If all 19 address lines of the EPMP are not required, PMA17 and PMA18 can be configured for other purposes. PMA17 can be used to control LED D4, while PMA18 can be reconfigured to function as an I/O on the PICtail Plus Expansion port. For more information on using the EPMP, refer to “Enhanced Parallel Master Port (EPMP)” (DS39730) for more information. 4.4.5.1 EXTERNAL SRAM The PIC24FJ256DA210 Development Board is provided with 512 Kbyte of external SRAM, populating U6. By default, only 256 out of the 512 KByte is enabled; this allows PMA17 to control LED D4 in the default board default configuration. If required, the SRAM may be upgraded to 1 MByte by replacing U6 with a different device. The SRAM interfaces with the microcontroller through the EPMP interface. Use of external SRAM is optional if internal 24/96 Kbyte RAM of PIC24FJ256DA210 cannot accommodate the required frame buffer size for a specific color depth and resolution combination. SRAM access time is an important aspect of the interface to the EPMP port. In most QVGA based applications, the use of a 55 ns access time is enough to meet the refresh requirements of the display. The use of a 10 ns access time SRAM on the board is due to the fact that VGA resolution display, which requires more bandwidth, can also be driven by the development board. The SRAM can be configured for one of three memory address ranges, shown in Table 4-7.

Set JP11 (callout 2) to position 1-2 to connect PMA17 to LED D4 only, and use that microcontroller pin to control the LED. Alternatively, remove jumper JP11 (disconnects PMA17 signal entirely). 2. If installed, remove resistor R63 (callout 2) (disconnects PMA18 signal). 3. For TFT displays using 8 bpp color depth, install jumper JP8 to enable Byte access addressing. To enable the 512 KByte range of external SRAM: 1. Set jumper JP11 (callout 1) to position 2-3 (connects PMA17 signal to the SRAM). 2. If installed, remove resistor R63 (callout 3) to disconnect PMA18 signal to the address 18 of the RAM. 3. Install jumper JP8 (callout 2) to enable Byte access in the external RAM. Byte access is needed when the color depth used for TFT displays is 8 bpp. To enable the full 1 MByte address range for the SRAM (assuming U6 is populated with a 1 Mbyte device): 1. Set jumper JP11 (callout 1) to position 2-3 (connects PMA17 signal to the SRAM). 2. Populate resistor R63 (callout 3) with a 0 resistor (connects PMA18 signal to the SRAM) 3. If installed, remove resistor R62 (callout 3) (disconnects PICtail Plus connector from PMA18). 4.

Development Board Hardware 4.4.5.2 EXTERNAL FLASH MEMORY The PIC24FJ256DA210 Development Board has two external Flash memory devices. Selection is controlled by jumper JP23. Only one can be enabled at any given time: • 512 Kbyte Parallel Flash (SST39LF400A), connected to the EPMP port. • 16 Mbits (2 Mbyte) SPI Serial Flash (SST25VF016B). Flash memory configuration uses the same jumpers and resistors as SRAM configuration (Figure 4-9). An additional jumper, JP23 (callout 1), selects between the serial and parallel devices. FIGURE 4-9: FLASH MEMORY CONFIGURATION 4 3 2 1 4.4.5.2.1 M Serial Flash Memory To use the SPI Flash memory, set jumper JP23 to bridge pins 2 and 3 (PMCS2 – SPI).

If installed, remove resistor R62 (callout 4) (disconnects PMA18 from the PICtail Plus expansion port). 4.4.6 PICtail™ Plus Card Modular Expansion Connector A 120-pin PICtail Plus connector (J8) is provided on the PIC24FJ256DA210 Development Board for expansion and integration of other solutions. At the time of this writing, the following daughter boards are supported on the PIC24FJ256DA210 Development Board: • • • • • • • PICtail Daughter Board for SD & MMC Cards (AC164122) Ethernet PICtail Plus Daughter Board (AC164123) Fast 100 Mbps Ethernet PICtail Plus Daughter Board (AC164132) MRF24WB0MA PICtail Plus Daughter Board (AC164136-4) MRF49XA PICtail Plus Daughter Board (AC164137-1 or AC164137-2) Speech Playback PICtail Plus Daughter Board (AC164125) IrDA® PICtail Plus Daughter Board (AC164124) Additional boards are planned to be available in the future. Users are encouraged to check the Microchip web site periodically for more information. To enable the support of multiple PICtail Plus Daughter Boards, the development board maps selected I/Os to multiple PICtail Plus pins. In some cases, using certain daughter boards may mean disabling some functionality on the development board. In general, when the PICtail Plus connector is in use, these development board features are not available: 1. All CTMU channels (most daughter boards). 2. EPMP Address lines PMA18 and PMA17. This reduces the accessible area of the parallel Flash device to 256 Kbytes, regardless of the device installed 3. PMP Byte Enable line PMBE1. This limits parallel Flash and SRAM devices to Word accesses; in turn, this limits display modes to 16 bpp mode. 4. USB OTG functionality (Device and Host modes are still available) DS51911A-page 46  2010 Microchip Technology Inc. Development Board Hardware 4.4.6.1 DAUGHTER BOARD-SPECIFIC HARDWARE MODIFICATIONS Depending on the PICtail Plus Daughter Board to be used, hardware modification to the development board may be required. The modifications re-route different signals from the microcontroller, particularly EPMP signals, to different pins of the connector. All changes consist of placing 0 resistors in designated areas to enable the connections, or removing existing resistors in other places to disable existing connections. All of the resistors are located in a single group adjacent to the Flash memory area, shown in Figure 4-10. They are also shown as a single group in Figure A-6 of the development board schematic. FIGURE 4-10: LOCATION OF CONFIGURATION RESISTORS M For additional information on the configuration resistors, as well as specific modifications for particular daughter boards, please refer to Appendix B. “Modifications for PICtail Plus Daughter Boards”. 4.4.7 Current Measurement To provide additional information on developing hardware solutions, the development board includes current measurement points at three locations. These permit the current drawn by the different branches of the development board to be measured separately. The measurement points are unpopulated jumpers at JP1, JP2 and JP3 (Figure 4-11, callouts 1,2 and 3, respectively). To measure current, cut the trace on the reverse side of the board that shorts the two vias for the jumper, then insert the current measuring device between the two vias. JP3 can be used to measure the total current drawn by the board from the 9V power supply. JP1 can be used to measure the total current (at 3.3V) drawn by the microcontroller, and JP2 can be used to measure the total current drawn by the remaining 3.3V branch of the board. The current drawn by the 5V branch can be measured by subtracting the sum of the currents of JP1 and JP2 from the total current measured at JP3.  2010 Microchip Technology Inc.

The configurations are selected by the ALTPMP Configuration bit; this allows some flexibility in hardware design by remapping several address and Chip Select lines to different pins. Table 4-9 summarizes the differences. The development board is designed with the assumption that the Enhanced PMP interface is in the alternate configuration (ALTPMP = 0). This allows the use of three additional analog pins that would otherwise be used by the EPMP module. Users should keep this in mind when designing applications that will be used with the development board.

PIC24FJ256DA210 DEVELOPMENT BOARD USER’S GUIDE Appendix B. Modifications for PICtail Plus Daughter Boards B.1 INTRODUCTION This appendix provides a detailed description of the modifying the development board for use with different PICtail Plus daughter boards. Topics include: • Overview of the PICtail Plus Interface • Modifications for Specific Daughter Boards B.2 OVERVIEW OF THE PICTAIL PLUS INTERFACE To maximize their versatility, many of Microchip’s development and demonstration boards are equipped with the PICtail Plus interface. This allows boards with a standardized edge connector to directly access the I/O lines of each other’s microcontrollers and expand their functionality. In most cases, this is used to allow a more fully-featured board (such as the PIC24FJ256DA210 Development Board) to connect to a PICtail Plus daughter card and add new features to a pretape application (for example, adding 100 Mbps Ethernet using the Fast 100 Mbps Ethernet Daughter Board). The basis for the design of the PICtail Plus interface is Microchip’s adherence to a standard migration pathway throughout its microcontroller families: that is, for a given microcontroller package pin count, certain I/O ports are always located on specific pins of the PICtail Plus interface, and specific peripherals are almost always associated with specific I/O ports. This permits daughter boards to use a specific pin for SPI communication, for example, because microcontrollers will always have an SPI peripheral associated with that I/O pin, and that PICtail Plus connector pin. There are exceptions, however. Because of its complex graphics interface and enhanced PMP, the PIC24FJ256DA210 microcontroller does not map I/O ports and peripherals in the same way as other 100-pin devices are mapped. To maximize compatibility, this requires a change of the PICtail Plus mapping for the PIC24FJ256DA210 Development Board. The complete mapping from microcontroller to interface are shown in Table B-1. Since PICtail Plus-compatible daughter boards are designed to the standard interface, some additional remapping of the interface is needed to make the PIC24FJ256DA210 Development Board compatible. Provisions to do this are made by connecting a group of I/O lines the resistor bank described in Section 4.4.6 “PICtail™ Plus Card Modular Expansion Connector”. Populating or removing specific resistors in this bank allows the remapping of certain signals and restoring compatibility with specific daughter boards. As of this writing, the development board can be made compatible with all available PICtail Plus daughter boards. A list of specific signals controlled by the resistor bank is provided in Table B-2; note that some signals are routed to multiple pins on the PICtail Plus interface by default to maximize compatibility. Table B-3 shows the same information to specifically highlight which signals can be remapped to a particular pin. Section B.3 “Modifications for Specific Daughter Boards” describes the specific resistor changes required for each PICtail Plus daughter board.  2010 Microchip Technology Inc.
