LAUNCHXL-F280049C: CAN ex5 connection issues

Part Number: LAUNCHXL-F280049C

Tool/software:

I have two F280049C boards and am trying to run the can ex5 program with one board being the transmitter and the other being the receiver. I did the pin configuration setup and the made sure to use the right debug probe/config file but for some reason I don't see messages being sent from one board to another. I noticed that the transmitter board would get stuck in the while(txMsgSuccessful) loop and the receiver would get stuck in the while(rxMsgCount) loop. I also noticed that I am not able to plug in both boards to the same computer and run two different versions of CCS like the can ex5 video. Therefore, this was being done using two different computers with the boards being connected by the three jumper wires.

  • Hi Adhav,

    1. The example ex5 uses GPIO30 and GPIO31 as CAN_RX and CAN_TX. But the CAN_TX and CAN_RX on Launchpad are connected to GPIO32 and GPIO33

    Please use the following code to config CAN (device.h):

    2. To use CAN signals on J4, please set the dip switch S9 properly.
