Platform:

OEM719, OEM729, OEM7700, OEM7720, PwrPak7, CPT7, CPT7700, SMART7

The USERCANDATA log reports the received CAN basic frame data. Depending on the number of frames in the RX FIFO buffer, there will be multiple USERCANDATA logs published. There is an index field indicating the order of the frames received.

USERCANDATA messages are asynchronously published based on Message ID matches set by the acceptance filters of the USERCANOPEN command.

Message ID: 2316

Recommended Input:

log USERCANDATA onnew
