Hardware requirements

  • Micro USB cables

  • FRDM-KE16Z board

  • Personal Computer

Board settings

The example requires connecting between CAN pins of two FRDM-KE16Z boards. The connection should be set as follows:

Between boards:

  • J12-1 node A, J12-1 node B

  • J12-2 node A, J12-2 node B

  • J12-3 node A, J12-3 node B

Prepare the Demo

  1. Connect a micro USB cable between the PC host and the OpenSDA USB on the board.

  2. Open a serial terminal on PC for OpenSDA serial device with these settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  3. Download the program to the target board.

  4. Either press the reset button on your board or launch the debugger in your IDE to begin running the example.

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:

********* MSCAN Interrupt EXAMPLE *********
    Message format: Standard (11 bit id)
    Interrupt Mode: Enabled
    Operation Mode: TX and RX --> Normal
*********************************************

Please select local node as A or B:
Note: Node B should start first.
