I am trying to communicate with the canbus but the calculated CRC does not seem to conform to the Bosch Can 2.0 standard (http://esd.cs.ucr.edu/webres/can20.pdf).
I can read all messages from velbus without problems (ignoring CRC)
I can also send messages and receive them in my own hardware modules (using standard CRC)
I cannot sent messages to velbus devices (USB interface)!
Used components PICHJ128 family (Microchip) with integrated ECAN module + MCP2551 transceiver.
Any help appreciated
