Flexcan - Receiving RTR requests

Question asked by Ahlan Marriott on Feb 5, 2014

Is there any way using MCF5235 Flexcan that I can read all the CAN messages on the CAN bus including remote transmission requests?


When I setup Rx buffer 15 mask to all don't care I receive all the messages except RTR messages.

Page 21-29 of the MCF5235 RM says that "A received remote frame is not stored in a receive buffer. It is only used to trigger automatic transmission of a frame in response"


However I don't want to react to the RTR I merely what to monitor *all* the CAN bus traffic.


Has anyone any ideas how I might do that?


Best wishes,
