Basic CAN sniffer/monitor

Could you help me out creating a small example program to digest CAN 2.0B (Extended 29b address range) messages to simply list them on the serial terminal. using FRDM-KW36

 

How to activate/deactivate acknowledgements?

 

I have the idea my messages come too fast, 4 messages in less than 3msec, which corrupts somehow the receiver circuitry/code.

 

Somehow I have to learn how NXP addresses these aspects.

I'm not a formal µC programmer but an application development engineer and I would like to create a POC to showcase an alternative approach to a problem.

I'm close to stop using the NXP solution, but I can't believe NXP is not able to handle these CAN applications.
