控制器局域网(CAN)通信的主要功能是实现其节点设备和上位机之间数据信息和控制信息的交互,CAN与PC机RS-232网络间的协议转换需要用转换器来完成.介绍了基于LPC1768处理器与RT-Thread系统的转换器的实现过程,完成了CAN与RS-232网路间的无缝通信.实践证明,此方案对CAN组网应用具有实际意义.%The main function of the controller area network (CAN) is to implement the interaction between the node device and the hostcomputer for data and control information. The converter is needed to conduct the protocols between CAN and RS-232 network of PC. Theimplementing procedures of the converter between RT-Thread system and the processor based on LPC1768 to realize the seamless communicationbetween CAN and RS-232 networking are introduced. The practice verifies that this scheme possesses actual significance to CAN networkingapplication.
