Hardware requirements

  • Mini USB cable

  • TWR-MC56F8400 board

  • Personal Computer

Board hardware common setting

  1. Power setting:

    Connect J11 pin1 and pin2 Connect J6 pin1 and J7 pin2

  2. UART setting:

    Connect J8 pin3 and pin4 Connect J9 pin3 and pin4

  3. Onboard OSJTAG debugger setting:

    Connect J20 pin1 and pin2. Leave J17 open. Note: J17 is only used(connected) when firmware update for onboard debugger OSJTAG. Connect J21 pin 1-2, 3-4, 5-6, 7-8, to setup onboard debugger OSJTAG. Note: when use external debugger(connected to J14), leave all J21 pins open

Board settings

  • Connect J13-4 (CAN_H) of the two boards

  • Connect J13-3 (CAN_L) of the two boards

  • Connect J13-5 (GND) of the two boards

  • Short J16 1-2, 3-4 and J15 1-2 for each board

Prepare the Demo

  1. Connect USB cable between the host PC and the JM60 USB(J18) port on the target board. It setups OSJTAG and COM port in PC device manager.

  2. Open a serial terminal with the following settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  3. Download the program to the target board with OSJTAG debug configuration.

  4. Launch the debugger in your IDE to begin running the demo.

Running the demo

After connecting the two boards, these instructions display on each terminal window. One board must be chosen as node A and the other board as node B. (Note: Node B should start first) Data is sent continuously between the node A and the node B.

This message displays on the node A terminal:


********* FLEXCAN Interrupt EXAMPLE *********

    Message format: Standard (11 bit id)

    Message buffer 1 used for Rx.

    Message buffer 0 used for Tx.

    Interrupt Mode: Enabled

    Operation Mode: TX and RX --> Normal

*********************************************

Please select local node as A or B:

Note: Node B should start first.

Node:a

Press any key to trigger one-shot transmission

Rx MB ID: 0x123, Rx MB data: 0x0, Time stamp: 8877

Press any key to trigger the next transmission!

Rx MB ID: 0x123, Rx MB data: 0x1, Time stamp: 32459

Press any key to trigger the next transmission!
