CAN总线与PC串口双向转换器的设计

Design of Bidirectional Converter between CAN Bus and PC Serial Port

针对越来越多的CAN接口设备,设计了一种CAN总线与PC串口之间通信的双向转换器。阐述了转换器的硬件电路设计方法,介绍了CAN与PC机之间的数据收发过程,并给出CAN总线协议与串口协议转换的软件设计流程。

For a growing number of CAN interface equipment, a bidirectional converter is designed for communi-cation between CAN bus and PC serial port. The design method of hardware circuit of converter is described. Thedata sending and receiving process between CAN and PC is introduced, and the software design flow of conversionbetween CAN bus protocol and serial port protocol is given.
