MCU board to experiment with the CAN bus.

Circuit based on ATmega8515, SJA1000 and PCA82C251 (High Speed CAN). LCD and RS232 may be left off.

Can be used to compose and send messages and to receive message. The payload can contain 1 to 8 bytes. 11-bit and 29-bit identifiers are supported. With a little add-on circuit fault-tolrant CAN can be tested too.

Cable and connection problems can be detected.

Messages can be relayed to RS232 port.

Software written in BASCOM-AVR. Several versions featuring different functions are available in the attached archive. A description by the author (in Dutch!) is available as well.
