摘　　要：在对CAN控制器P80C592的应用中,通信是最重要的部分。CAN通信首先需要双方匹配总线波特率,这样就可以在CAN总线上发送和接收串行数据。要正确理解所接收的数据,需要通信双方制定相应的用户协议。而当多个站点进行通信时,需要某种机制来裁决总线使用权和数据接收方。最后,给出了5种数据错误检测方法和P80C592的通信流程。Communication plays an important role in the application of CANbased controller, P80C592. The communication of CAN firstly needs both sides to match the BUS baud rate, so that serial data can be transmitted and received on CAN BUS. To correctly understand the data received, the two sides of communication need establish the user protocol. When many stations communicate with the others, there need a certain method to decide the right of the BUS usage, and the data receiver. At last, five methods of the data error detection, and the communication flow of P80C592 are given.
