Hi, Is there any documentation about how Freemaster protocol is encoded (i.e. in CAN messages)?

I am trying to understand the low level of the communication driver code so I might be able to modify it for a specific application.

Thanks!

Dear Weilin Cao,

the FreeMASTER-over-CAN protocol uses the same command/response format as a "native" Serial protocol. The payload is split to 7-byte chunks and is transmitted over a simple CAN signalling protocol. I'm attaching a white paper which describes general concepts of both Serial protocol and also the CAN transport.

Best regards,

Michal
