Other Parts Discussed in Thread: TM4C129XNCZAD
We are running the can2enet demo on the TIDA-00203 where CAN packets are received on a CAN interface and then transmitted out Ethernet to a connected telnet session. An incoming CAN frame consists of the 11-bit Identifier, RTR bit, Data length, data field, and CRC. When we receive a CAN frame all of the CAN frame information is stripped out and all we are left with is the data field. This is expected. We were wondering how our application can get access to some of the other CAN frame fields like the 15-bit CRC and other fields in the frame. Is this at all possible somehow? Or are these additional CAN frame fields stripped out in hardware by the CAN controller built into the TM4C129XNCZAD and there is nothing that can ever be done to retrieve these other CAN frame fields? If it is possible to get them, what would need to be done?
