Introduction to the Starter Kit Thank you for purchasing the dsPIC33EV 5V CAN-LIN Starter Kit. This board features the dsPIC33EV256GM106 Digital Signal Controller (DSC) for automotive and motor control applications. The Starter Kit contains serial data ports for CAN, LIN and SENT, a self-contained USB programming/debug interface, and an expansion footprint for flexibility in application hardware development. This chapter introduces the Starter Kit and provides an overview of its features. Topics covered include: • • • • 1.1 Overview What’s In the Kit Hardware Installing Drivers for the Starter Kit OVERVIEW The dsPIC33EV 5V CAN-LIN Starter Kit is a stand-alone demonstration board, allowing users to explore three popular automotive and industrial serial data formats (CAN, LIN and SENT). The board uses the 5 VDC supplied by the host computer’s USB interface, consuming approximately 70 mA. The PICkit On-Board (PKOB) USB programmer and debugger allows simple programming without the need for an additional hardware interface. No other external tools are required to program the device. An optional ICSP™ interface also allows for debugging with more advanced tools. The Starter Kit board includes several analog features to showcase the capabilities of the dsPIC33EV256GM106 family. The included 64-pin digital signal controller integrates the following features: • • • • • • • One CAN module with 32 buffers and 16 receive filters Two SENT (Single Edge Nibble Transmission) modules Two UARTs with LIN/J2606 support SPI and I2C™ serial interfaces One high-speed (1.1 Msps), 10/12-bit A/D converter with multiple input channels One Charge Time Measurement Unit (CTMU) Six Pulse-Width Modulation (PWM) outputs In addition, the CAN-LIN Starter Kit board also provides: • • • • • • • Analog temperature sensor (MCP9701A) Ratiometric trim potentiometer CAN Interface (MCP2561) with DB9 male connector LIN Interface (MCP2021A) with required interface electronics Three general purpose momentary push buttons Three general purpose LEDs Breakout Connector footprint  2014 Microchip Technology Inc. DS50002311A-page 13 dsPIC33EV 5V CAN-LIN Starter Kit User’s Guide 1.2 WHAT’S IN THE KIT The dsPIC33EV 5V CAN-LIN Starter Kit contains the following: • dsPIC33EV 5V CAN-LIN Starter Kit board • USB cable (A to mini-B) • An insert card with links to the website for this manual, schematics and the demo application 1.3 STARTER KIT HARDWARE The CAN-LIN Starter Kit ships with a simple pre-programmed application to transmit or receive data packets that simulate sensor readings, using the three automotive data ports. The data transmitted is the temperature reading from the on-board temperature sensor, the 12-bit data from the potentiometer, and the status of the three user push buttons. External protocol analyzers can be used to read the transmitted data. In addition, the secondary UART channel sends an activity log of transmitted/received data via I/O pin RB4. See Section 2.3 “UART Monitoring Log” for details. To develop code and to program and debug the dsPIC33EV256GM106 DSC, you will need the latest versions of MPLAB X IDE (V2.10 or later) and MPLAB XC16 compiler (V1.23 or later). Figure 1-1 shows the Starter Kit board, along with the major hardware features.

It is responsible for managing communications for all three serial protocols, using dedicated hardware peripherals for CAN and SENT, and one of the DSC’s compatible UARTs for LIN. An external 8 MHz crystal (X1) provides stable timing. All of the I/O pins not used by the sensors and serial interfaces are available on the breakout connector. 2. User Push Buttons and LEDs: three push buttons (S1 through S3) are provided to simulate digital sensor data in the pre-programmed application. The switches and their associated red LEDs (LED1 through LED3) are connected to dedicated I/O port pins. The switches have external pull-ups, and thus read a logic low when depressed. The LEDs are lit when their port pins are driven high. The LEDs are low-current types, consuming approximately 2 mA each when lit. 3. Master Clear Push Button: pressing this button causes a Master Clear reset of the DSC and the running application. 4. Potentiometer (R14): the linear trim potentiometer is used to simulate analog sensor readings for the pre-programmed application. The wiper is connected to the DSC’s A/D converter; the body is connected between ground and I/O port RG8. Driving RG8 high makes the potentiometer a divider between VDD and ground. Driving RG8 low disables the potentiometer, and allows for reduced power consumption. R13 and C20 form a low-pass, anti-aliasing filter. 5. CAN Interface: this uses the Microchip MCP2561 CAN driver/receiver, which can operate up to 1 MB/s. Connections to external CAN devices are made through J2, a standard DB9 serial connector. An optional 120 bus termination resistor is controlled via jumper J7. 6. LIN Interface: this uses the Microchip MCP2021A LIN controller (U10), and is fully compliant with the LIN 2.x/SAE J2602-2 specifications. Screw terminal connections are provided for battery power in Master mode (J4) and data bus connections in Master and Slave modes (J8). Jumper J1 is used to select the operating mode. 7. SENT Interface: screw terminals (J9) are provided for data connections. The bus pull-up is controlled with jumper JP2. 8. ICSP Header (J10): space is provided for a standard 6-pin In-Circuit Serial Programming™ connector (FCI 68016-106HLF) for the dsPIC33EV256GM106 DSC. This allows for in-circuit emulation and debugging using Microchip’s MPLAB REAL ICE™ in-circuit emulator, as well as direct programming of the DSC. 9. Power LED (D5): this LED is lit when USB bus power is available to the USB connector. 10. USB Port (J6): the mini-B port provides programming/debugging connectivity and power to the Starter Kit. Bus power (+5 VDC) is provided to the DSC side of the Starter Kit through a noise filter network (L1/C47). Note: The CAN-LIN Starter Kit can only be powered through the USB port. No other provisions to supply power to the board are available. 11. PICkit 3 On Board (PKOB): the PIC24FJ256GB106 microcontroller provides a simple programming interface between the dsPIC33EV256GM106 DSC and MPLAB IDE software for programming and debugging. A 3.3V regulator (U8) provides power to the circuit. Since the DSC operates at 5V, level translators (U2 and U3) are used for the internal serial clock programming signals. Space for a legacy 6-pin PICkit programmer expansion header (J5) to program the PKOB microcontroller is also provided.  2014 Microchip Technology Inc. DS50002311A-page 15 dsPIC33EV 5V CAN-LIN Starter Kit User’s Guide 12. Current Measurement Shunt (JP1): the operating current of the DSC can be measured here by removing the jumper and placing an ammeter across the pins. Running the demo at 40 MIPS results in current consumption of approximately 34 mA (from the +5VDC rail). 13. Temperature Sensor (U7): the MCP9701A analog temperature sensor measures the board’s temperature; its analog output is connected to AN18 of the 12-bit ADC. The sensor’s scale is 19.5 mV/°C nominal. The ADC uses VDD (5V) as its reference, so each bit represents a 12.2 mV step. The circuit can resolve ±1°C. 14. Breakout Connector (J3): many of the DSC’s I/O pins are accessible through this connector footprint. The user can solder in a male or female 2x25 pin header (2.54mm pin spacing). Individual wires can be soldered into the connector holes. Table 1-1 lists the expansion header’s connections to the DSC.

The first time the Starter Kit is attached to the IDE, a notification window may appear that USB drivers are being installed.  2014 Microchip Technology Inc. DS50002311A-page 17 dsPIC33EV 5V CAN-LIN Starter Kit User’s Guide NOTES: DS50002311A-page 18  2014 Microchip Technology Inc. dsPIC33EV 5V CAN-LIN STARTER KIT USER’S GUIDE Chapter 2. The Demonstration Application The Starter Kit board is pre-programmed with a small application to demonstrate its functionality in its three serial automotive interfaces (CAN, LIN and SENT). The application can either operate as a Transmitter (Master) or as a Receiver (Slave), but not both at once. The application’s mode is set at power-up, or when a Master Clear event occurs, as follows: • if none of the push buttons are depressed during power-up or while the MCLR push button is pressed, the three LEDs will light in sequence 1-2-3, and turn off in reverse sequence (3-2-1). The board is now in Transmit/Master mode. • if any of the push buttons are depressed during power-up or while the MCLR push button is pressed, all three LEDs will blink together five times, and then remain lit until the push button(s) are released. This places the board in Receive/Slave mode. 2.1 TRANSMIT/MASTER MODE When the application is running in Transmit mode, it executes an endless one-second loop as the main routine, which performs the following: 1. The state of the push buttons is read, and the corresponding LED is lit if the button is pressed. 2. The temperature sensor is sampled, and its analog output converted. 3. RG8 is driven high (+5V), and the voltage on the potentiometer is read. 4. The results of (1), (2) and (3) are formatted and transmitted on each of the three serial interfaces, starting with the CAN interface. 5. The UART monitor sends a formatted ASCII text message from pin RB4 (see Section 2.3 “UART Monitoring Log” for details). 6. The application waits until the timer tick ends, and then repeats the process. While the LIN and SENT interfaces do not need to be connected in Transmit mode, an external active CAN bus or CAN analyzer must be connected to the CAN port; this is due to the CAN requirement of receiving an external ACK signal before transmitting a message. Unless the CAN portion of the application is disabled, the application will pause and wait indefinitely without an external connection, and no LIN or SENT data will be transmitted. See Section 3.1 “Removing CAN from the Demo Application” for information on reconfiguring the application.  2014 Microchip Technology Inc. DS50002311A-page 19 dsPIC33EV 5V CAN-LIN Starter Kit User’s Guide 2.1.1 SENT Data Transmission Formatting The SENT message consists of the following: • • • • A Synchronization/Calibration period (pulse) of 56 tick times A Status nibble of 12 to 27 tick times. This is user defined Up to six data nibbles of 12 to 27 tick times. The demo uses 6 nibbles (3 bytes) A CRC nibble of 12 to 27 tick times The tick time is set by a #define statement at 50 µs, with an allowable range of 3 µs to 90 µs. The SENT protocol uses nibbles, not bytes or words, to format the message. In the demo application, the Status nibble encodes the state of the user-defined push buttons. The data nibbles encode the potentiometer and temperature sensor readings. The Status and data nibbles are: • Status: 0 S3 S2 S1, where S1 through S3 represents the status of the push buttons (a ‘1’ indicates that corresponding switch is pressed). The value of this nibble reflects which button (if any) is pressed • Nibbles 1 through 3: 12 bits of the ADC conversion value for the potentiometer reading (MSbit to LSbit) • Nibbles 4 through 6: 12 bits of the ADC conversion value for the temperature sensor (MSbit to LSbit) The CRC is generated by the SENT module in hardware, and is not calculated by the application. Figure 2-1 shows a typical screen capture of SENT data transmitted by the application. This data was captured using the KOPF Automotive Interface 4 analyzer and KFlexExplorer software (KOPF GmbH). FIGURE 2-1: DS50002311A-page 20 SENT MESSAGES FROM THE STARTER KIT  2014 Microchip Technology Inc. The Demonstration Application 2.1.1.1 CONNECTING HARDWARE FOR SENT DATA TRANSMISSION Connection to another SENT device is by two wires, SIGNAL and GROUND. The connections are made via J9. The SENT bus requires a pull-up resistor, which is enabled by installing Jumper JP2. If two Starter Kit boards are connected, enable the pull-up on only one of the boards; remove the JP2 jumper on the other board. Similarly, if the Starter Kit is connected to an existing SENT network which has a pull-up installed, remove the JP2 jumper. Note: 2.1.2 The rise-time control filter on the Starter Kit is not guaranteed to meet the requirements of the SENT standard in all possible applications. Refer to SAE J2716 for filter design guidelines. LIN Data Transmission Formatting The various LIN timing parameters are set in the demo application in a series of #define statements (Example 2-1). Connection to existing LIN networks or peripherals may require adjusting these parameters. The constant FCAN is the MIPS running frequency in Hz. EXAMPLE 2-1: #define #define #define #define #define #define LIN TIMING PARAMETERS FCAN 40000000 LIN_BAUD 4800 LIN_BIT_TIME ((1000000/LIN_BAUD) + 0.5) LIN_BRGVAL ((FCAN/LIN_BAUD)/16) – 1 LIN_ID 0x23 LIN_BIT_STUFF 0x4 The data is transmitted as follows: 1. The ID byte, which includes two parity bits. The ID is set as a #define in the demo program, and may be changed to any valid byte. The application uses 0x23 by default, which is transmitted with parity as 0xE2. 2. The second byte is the data for the three push button switches. S1 represents the LSbit (bit 0), S2 is bit 1 and S3 is bit 2. A ‘1’ in a bit position shows the corresponding switch is depressed. Note that the switches are not debounced by the application, and the switch states are sampled once every second; therefore, there may be a delay to register a key press in the serial data. 3. The next two bytes are the raw temperature readings from the ADC. At room temperature, expected data values are from 0x02D0 to 0x0320. The application takes four readings and then averages them to send the final result. 4. The next two bytes are the potentiometer value from the ADC. The range is approximately 0x000 to 0x0FFF (a small offset value is possible). 5. The final byte is the checksum, computed per LIN specification. Note that this is an enhanced checksum calculation, which includes the ID byte in the calculation. Figure 2-2 shows the LIN data output from the application, captured by using the Microchip LIN Serial Adapter (Microchip part # APGDT001) and associated software. This shows the output of the LIN port running the demo software. To set this in the LIN analyzer application, open the Setup menu and change the settings at the Setup dialog to: • Baud Rate: 4800 • Timeout (ms): 1000 • COM Port: “APG USB to LIN 0”  2014 Microchip Technology Inc.

The connections between the LIN bus (or other LIN device) and the Starter Kit are different for Transmit and Receive modes. Table 2-1 summarized the differences. In Transmit (Master) mode, the +12VDC is applied to the BAT terminal of J4, and the battery ground is connected to the GND terminal. The LIN signal is applied to the SIG terminal of J8. The SIG terminal is for the LIN signal wire, and the GND terminal is used for the LIN ground. In addition, jumper J1 is set to position 1-2 for Transmit mode. In Receive (Slave mode), J4 is not used. The +12 VDC is supplied over the bus POWER wire, which is connected to the + terminal of J8. The SIG terminal is connected to the LIN SIGNAL wire, and GND is for the GROUND wire. Jumper J1 is set to position 2-3 for Receive mode.

The SID. The demo code arbitrarily uses 0x123, which is set by the #define MSG_SID statement. It may be changed to any valid SID. 2. The DLC byte, which shows six bytes of data are to be transmitted. 3. The next two bytes (DATA 0 and DATA 1) are the data for the three switches. The switch data appears on DATA 0, while DATA 1 is 0x00. S1 is the LSBit (bit 0), S2 is bit 1 and S3 is bit 2. A ‘1’ in a bit position shows the corresponding switch is depressed. Note that the switches are not debounced by the application, and the switch state are sampled once every second; therefore, there may be a delay to register a key press in the serial data. 4. The following two bytes (DATA 2 and DATA 3) are the raw temperature readings from the ADC. At room temperature, expected data values are from 0x02D0 to 0x0320. The application takes four readings and then averages them to send the final result. DATA3 is the Most Significant Byte. 5. The final two bytes (DATA 4 and DATA 5) are the potentiometer value from the ADC. The range is approximately 0x000 to 0x0FFF (a small offset value is possible). DATA 5 is the Most Significant Byte. Figure 2-3 shows a typical CAN message from the demo application, as captured using the Microchip CAN Bus Analyzer (Microchip part # APGDT002) and associated software running on Windows 7. This shows a potentiometer value reading of 0x057D, and a raw temperature reading of 0x02E4. The CAN Analyzer shows that the CAN messages arrive 250 ms apart, as set by the application’s main timer loop. The CAN Analyzer must be configured to the demo application’s parameters with the Setup dialog (Setup > Hardware Setup). The correct setting are: • Bitrate Control: 250 kbps • Mode Control: Normal • Termination Control: On FIGURE 2-3:  2014 Microchip Technology Inc. CAN MESSAGES FROM THE STARTER KIT DS50002311A-page 23 dsPIC33EV 5V CAN-LIN Starter Kit User’s Guide 2.1.3.1 CONNECTING HARDWARE FOR CAN DATA TRANSMISSION The CAN bus should be double-terminated with 120 resistors at each end of the CAN cable. Jumper J7 controls cable termination across the CAN data lines. When the jumper is in the TERM position (positions 2-3), a 120 resistor is connected across the cable. When connecting two CAN-LIN Starter Kit boards to each other via a DB9 female-to-female serial cable, place the J7 jumpers in the TERM position on both boards. Do not use more than two bus termination resistors. The CAN connector (J2) follows the de facto industry standard for signal connection. Table 2 lists the signal pins. TABLE 2-2: CAN CONNECTOR PINOUT (J2) DB9 Pin 2.1.3.2 CAN Signal Name 1 NC 2 CAN_L 3 Ground 4 NC 5 NC 6 Ground 7 CAN_H 8 NC 9 NC SPECIAL CONSIDERATIONS FOR CAN For the demo application to properly execute, the CAN port must be connected to an active CAN bus or CAN analyzer tool that provides an Acknowledge (ACK) signal to the Starter Kit. If it is not connected, the demo application’s main loop will hang, waiting for an ACK signal to be received; no LIN or SENT transmissions will be sent. The application can be modified and re-compiled to disable CAN functionality and only run the SENT and LIN portions. See Section 3.1 “Removing CAN from the Demo Application” for details. DS50002311A-page 24  2014 Microchip Technology Inc. The Demonstration Application 2.2 RECEIVE/SLAVE MODE Receive/Slave mode is set by pressing and releasing the MCLR push button while simultaneously pressing and holding any of the three push button switches. The three LEDs rapidly flash in unison, then stay lit. Once they are all lit, release the held push button. While in Receive mode, the application waits for any of the three serial interfaces to receive and process a valid message from another CAN-LIN Starter Kit running the demo application in Transmit mode, or other external source. Once processed, the LEDs will momentarily flash to indicate a valid received message, as follows: • Valid CAN message: LED1 • Valid LIN message: LED2 • Valid SENT message: LED3 It is possible that messages sent by other sources will show a valid received message if they are the correct baud/bit rates and have the same number of data bytes transmitted as the demo application. Messages can be received from any or all of the connected ports at once, and multiple messages will be validated. 2.3 UART MONITORING LOG The demo application contains an independent message-logging UART in both Transmit and Receive mode. The UART uses ASCII-encoded serial data at 38,400 baud, 8-bit data, with 1 Start bit, 1 Stop bit and no parity (38400-8-1-1-N). The serial data is sent to I/O pin RB4 on the Expansion Connector (J3). In Transmit mode, the logger reports the current temperature (°C), the measured potentiometer voltage (V) and the status of each push button switch. This data is then encoded and sent over each interface (in the order of SENT, LIN, then CAN). Figure 2-4 displays a typical logging message in Transmit mode, as viewed on a terminal application. Note that this ASCII data is not what is physically sent over the interfaces. The data sent is raw data as described in the prior sections for each interface. The data is described as local, as this is the data measured by the board about to Transmit. FIGURE 2-4:  2014 Microchip Technology Inc. UART TRANSMIT LOG (TERMINAL DISPLAY) DS50002311A-page 25 dsPIC33EV 5V CAN-LIN Starter Kit User’s Guide The UART logging code will decode the incoming messages if the board is in Receive mode. CAN and LIN messages contain ID byte fields, and the logger will display these as well. Figure 2-5 shows a typical decoded CAN message sent by another CAN-LIN Starter Kit. The first line shows that a CAN message with an SID of 0x123 (the demo application default SID) has been received. FIGURE 2-5: UART RECEIVE LOG (TERMINAL DISPLAY) The application assumes that incoming messages in Receive mode are coming from another CAN-LIN Starter Kit, and is thus hard-coded to parse and decode its own messages. Of course, it is possible to have non-demo messages received and parsed, but the displayed data will be random; the only fields properly displayed will be the ID fields for CAN and LIN. The source code can be edited and re-compiled to parse any message, or to simply display the raw data bytes like a typical analyzer. The CAN portion only accepts SID messages. EID messages are not handled. 2.3.1 Connecting the Logger To A USB Host The +5V UART serial data present on I/O pin RB4 must somehow get to a computer terminal. The Microchip MCP2200 Breakout Module (Microchip part # ADM00393) provides one simple way to create a serial-to-USB interface. The module is available separately at the microchipDIRECT web site (www.microchipdirect.com). The Breakout Module needs only three connections to the Starter Kit board via the expansion riser (Table 2-3); none of the other ports on the Breakout Module are used. The logger can then communicate to a host computer or terminal over USB. Driver support for the MCP2200 for both Windows and Linux is available. TABLE 2-3: Note: DS50002311A-page 26 CONNECTIONS FOR THE BREAKOUT MODULE Breakout Board Signal Expansion Connector Signal RX RB4 VDD DVDD G GND The MCP2200 Breakout Module can operate on a VDD of either 3.3V or 5V, which is selectable by a jumper. For this application, make sure that the jumper is configured for 5V (positions 2-3).  2014 Microchip Technology Inc. dsPIC33EV 5V CAN-LIN STARTER KIT USER’S GUIDE Chapter 3. Modifying the Application The pre-programmed demo application for the Starter Kit can be easily modified to change its operation, or removed and replaced with your own hardware-appropriate application. To modify the application, develop new code, and/or program and debug the dsPIC33EV256GM106 DSC, you will need the latest versions of MPLAB X IDE (V2.10 or later) and MPLAB XC16 compiler (V1.23 or later). In addition, you will need the Starter Kit demo application software, available as a zipped MPLAB X IDE project file from the Microchip web site. After unzipping the application archive and launching MPLAB X IDE, the Starter Kit Demo project folder will appear in the Projects tab in the main view. The source code for the demo application is a single C file, 33EV_main_v11.c. (no header files). Before starting, verify that the project is configured correctly: 1. Right click on the folder, and select Properties. 2. In the Project Properties window, verify that the selected target device is the dsPIC33EV256GM106. 3. If the Starter Kit is connected to the computer via the USB port, the serial number associated with this Starter Kit’s PKOB should be displayed in the Hardware Tool window, located in the Project Properties window. (Note that the serial number will be unique for each PKOB.) 3.1 REMOVING CAN FROM THE DEMO APPLICATION The pre-programmed Starter Kit application can be modified and re-compiled to omit the CAN portion of the demo. To do this: 1. Open the source file (33EV_main_v11.c) in the MPLAB X IDE editor, or in a suitable text editor. 2. Perform a text search to find the main function call for the CAN routine: CAN_Transmit(); This code will be near line 472 of the source file. 3. Comment out that line. 4. Save and close the file. 5. Re-compile the source code, and load it into the DSC. The demo application should now execute only the LIN and SENT portions. The overall one-second loop timing of the application will remain the same.  2014 Microchip Technology Inc.

Troubleshooting This chapter discusses common operational issues and how to resolve them. 1. The demo application does not run. The Starter Kit board must be plugged into a powered USB hub, computer or other USB Host device that supplies at least 80 mA. Start by plugging into the USB Device port, J2. LED D5 should light when VBUS is detected. If D5 is not lit, verify that the USB Host side port is functional. Verify that Current Measurement Shunt JP1 is in place. The default application requires that the Starter Kit be connected to an active CAN bus or CAN analyzer. If it not connected, the demo will hang in its main loop and fail to run at all. If a CAN bus or analyzer is not available, it will be necessary to disable the CAN portion of the application. See Section 3.1 “Removing CAN from the Demo Application” for how to do this. 2. LIN (or SENT) data cannot be detected by the external bus analyzers. Verify that the Signal and Ground wires (and Power for LIN) for the affected protocol are connected to the Starter Kit correctly. Note that for the LIN protocol, different connections are used when the Starter Kit is in Transmit or Receive mode. For LIN, verify that the position of jumper J1 is in the proper position for the Starter Kit’s current mode. For SENT, verify that jumper JP2 is installed, enabling the pull-up resistor. 3. The Starter Kit is correctly connected to an external CAN bus or CAN Analyzer, but the external device is having problems receiving CAN messages from the Starter Kit. Verify that the CAN bus is properly terminated. If there are only two devices connected (e.g., the Starter Kit and an analyzer), verify that the CAN terminating resistor is enabled (jumper J7 is installed), and that the other device is properly terminated. If there are more than two devices, verify that two and only two are terminated. Verify that the CAN baud rate is set at 250 kbps. When using the CAN analyzer software provided with the Microchip CAN Bus Analyzer, use the Setup dialog (Setup > Hardware Setup) to check and/or change the setting. (For other CAN analyzer packages, refer to the instructions provided with the software.)  2014 Microchip Technology Inc.
