LAUNCHXL-F280049C: LAUNCHXL-F280049C: can bus transmit and receive

Part Number: LAUNCHXL-F280049C

Hi Team,

Good day! I'm posting this in behalf of the customer. Here it is.

I have the development board Launchxl-F280049C. I am trying to use can bus as a receiver and transmitter. I used two examples. can_ex1_loopback and can_ex5_transmit_receive.

With can_ex1_loopback I do not think I can sense the can-Lo and can-Hi so that is why I chose to use can_ex5_transmit_receive

I have an oscilloscope to sense the can-Hi and can-Lo signals. I am also using Arduino uno with mcp2515 for debugging the can bus and for analysis. With Arduino uno I can transmit can messages and I can see the signals on oscilloscope.

with Launchxl-F280049C and using the can_ex5_transmit_receive example, I am still not able to sense can-Lo or can-Hi signals on the J14. when debugging, I see that it is stuck in "while(txMsgSuccessful);" when using #define transmit and it is stuck in the line "while(rxMsgCount)" when it is working in receive mode

Best regards,

Jonathan
