摘要
本文介绍了一个基于CAN总线的数据采集系统设计实例。可以作为CAN总线系统节点模块的最小构成,CAN控制器(SJA1000)、微处理器(AT89C51)和CAN总线驱动器(82C250)构建了CAN的通信节点。并阐述了该通信节点的通信原理和SJA1000的初始化程序框图,以及调试成功的SJA1000初始化程序代码。文未对系统的应用结果作了简要概述。
This paper describes the design of data acquisition system with CAN bus. As the smallest architecture of CAN network communication node.it is composed of SJA1000,AT89C51,PCA82C250 and X25045. The initializing program of SJA1000 is given. At last,the application result is introduced.
