MCAN LPC55S1X

[Nadia]

Hello to all.
I am trying to make a communication from the CAN protocol. To do this, as well as reading the relevant documentation for both the micro and the communications protocol, I have uploaded an example to see how it works. It is a bit confusing for me, could someone explain me in which part of the example code I can access the data that is sent at the beginning of the frame according to the CAN protocol? Also could you tell me in which part of the code I can access the ID identifier data according to the CAN protocol?

Thank you very much.
Best regards

Hi Nadia,

By the data in the beginning on the frame do you mean identifier as well?

This information is contained in the txFrame and rxFrame structures of the MCAN examples.

Have a great day,

Felipe

Ok, and how would I cut the transmission, I mean, I'm using the MCAN_TransferSendNonBlocking function, and it never stops, I just want to send the data once and cut the transmission, how should I do it, that the transmission doesn't stop means that it's being done wrong?

Best regards.

Hi Nadia,

This is because the transmission is not being completed correctly, therefore, MCAN module generates retransmission. Please check description below from the UM.
