Design of Communication Node Based on CAN Bus

CAN bus is the most widely used vehicle network bus, and a communication node design based on CAN bus was proposed. The design used SJA1000 as the bus controller and TJA1050 as the bus transceiver of the communication module, which can realize the point-to-point and point-to-multipoint reception and transmission of messages. The hardware circuit design and software programming method were introduced in detail.
