There are a few people doing their own funky things on top of Velbus.

Have a search of the forum, you’ll find a few.

Canbus 2.0B Crc calculation

Hi 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). Notes: 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 …

Arduino with CAN shield to connect with Velbus

Hi, This weekend, I have written a Library for Arduino to communicate with Velbus through a CAN shield. I have posted the library on Arduino’s forum: forum.arduino.cc/index.php?topic=185743.msg1375617#msg1375617 (you must be logged in on the Arduino forum to download the file).
