摘要
介绍了一种CAN总线网络节点电路设计方案,微处理器采用AT89S52单片机,控制器和收发器分别采用PHILIPS公司的SJA1000和PCA82C250。给出了CAN总线节点的硬件和软件设计方案。软件设计由三部分组成,分别是SJA1000初始化程序、发送报文程序、接收报文程序。
This paper introduces a design of CAN-bus interface,using SCM AT89S52 as MCU,and SJA1000 and PCA82C250 made by PHILIPS are used in the controller and the transceiver respectively.It describes the designs of hardware and software.The software design composes of three parts such as initialization,transmission data and receiving data.
