Developer notes to evaluate

We don't want to duplicate their docs, but evaluate how it competes with HW implemented CAN (in LPC ARM) or modbus over serial (or profibus or similar).

Investigation revealed that caraca sw and hw is useless for us, because

Main questions:

CPU overhead


ATmega88/168 or similar uC (or PC) with HW UART but without HW CAN can talk to the ARM efficiently at 115200 baud, but not via 100% compatible CAN protocol. The solution is to
