摘　　要：针对单片机的CAN(Controller Area Network)串行通信,提出了一种由C8051F02X系列单片机、CAN接口控制器以及串行收发器构成的多点通信网络,介绍了通信节点的硬件电路设计和软件处理流程,详细阐述了CAN帧结构、数据流的收发问题,并针对CAN总线网络的同步方式以及CAN接口控制器进行了分析。Aiming at the CAN serial communication implemented on Micro-Controller Unit （MCU）, this paper proposes a type of multi-point communication network composed of C8051F02X series MCU, CAN port control chip and serial transceivers. The hardware circuit design and software flow chart are introduced at the beginning. Then the data stream pickup and delivery problem and the CAN frame structure are illustrated in detail. At last analysis is presented for synchronization of CAN bus network and CAN port control chip.
