Research on Intelligence Node of CAN Bus Based on MPC565

The intelligent node of CAN bus system in automobile assembly controller was designed by the TouCAN module of micro controller MotorolaMPC565 and the PCA82C250 bus transceiver. On the analysis of the technology characters and system structure of the CAN bus system, the network model of intelligent node communication was built and the hardware and software systems of the intelligent node were designed. And the communication test was done between the automobile assembly controller and Electronic Control Unit. The results of the test indicate that the designed intelligent node meet the assembly controller’s requirements and have better communication effects.
