Two ATmega/MCP2515/PCA-combinations are connected to the bus and send/receive CAN

to the ATmega and the MCP2515 a Philips PCA82C250 CAN controller interface is

should be used. Autobauding is a planned extension but not implemented yet. Additionally

a 4MHz clock for the MCP2515. The internal R/C my have to be tuned by using

In this design an ATmega16 is driven by the internal R/C at 8MHz and generates
