摘要
给出了一种实现 CAN总线与 RS2 3 2之间数据的转换的方法及过程 ,主控单元为单片机 P89C5 1,其中涉及到CAN芯片 SJA10 0 0以及串口扩展芯片 ST16C65 4的应用。作者分别以设计原理、硬件设计及软件设计三部分来介绍 ,并着重介绍了软件部分的功能实现过程 ,其中 CA N接口部分按照 CAN的 2 .0 B协议来执行。
There is a kind of method, which uses single chip microcomputer 89C51 realize data conversion between CAN bus and RS232. It involves application of CAN chip SJA1000 and series port extend chip ST16C654. The paper is divided three parts(principle of designation, hardware designation, and software designation), and the realizing process of software functions is introduced especially. CAN Interface executive according to protocol 2.0B of CAN.
