S12ZVC CANBUS PROBLEM

akguen — Mon, 14 Jun 2021 13:45:27 GMT

Hello there
I'm trying to communicate 2 NXP over canbus. But CAN1_OnFullRxBuffer interrupt is not triggered. Hardware checked, no problem.

error = CAN1_SendFrame(0,canStart,DATA_FRAME,sizeof(sData),sData);

error return 11

Any ideas on what the problem is?

Best regards,

Hello Akguen,

Thank you for learning CAN. I want suggest you materials for your help:

The CAN-Bus specs:

The attached SW examples for the ZVC family of MCUs.

For the right CAN communication the CAN module has to be properly set-up. The examples in the previous links can help you to solve your task and reach success.
