S12ZVC CANBUS PROBLEM

[akguen]

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 AN1798, AN4975:

• 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.
