Abstract:The efficient data transmission ability and the advantages of strong anti-interference of CAN Bus technology, make it widely applied in many fields. This paper presents a kind of automotive instrument display design system based on CAN bus, which use the STC89C52 as the core hardware platform for automotive instrument, and uC/OS-II embedded operating system as software. Through the practical operation shows that, based on the CAN bus automotive instrument stability, reliability and accuracy than the traditional instruments superior car. Based on the CAN bus in the fault-tolerant automotive instrumentation and data exchange and other aspects of anti-interference than the traditional instruments superior car.
Key words:CAN bus;automotive electronics;embedded systems;integrated instrument
