IBM-PC微机与MCS-51单片机的串行数据通讯

DATA SERIAL CORNMUNICATION BETWEEN IBM—PC AND MCS—51

介绍IBM-PC微机和单片机进行串行通讯的方法,详细分析了通讯中的一些关键技术问题,并给出了部分硬件接口和软件程序。实践证明,文中提出的方法是可行的,可用于单片机开发及以微机作为中心控制机与多个单片机实时通讯。

This paper describes the data serial commumnication betweenIBM-PC microcomputer awd MCS-51 single-chip microcomputer. Some impor-tant points are analysed. Some esawples of software and interface kardware are gir-ven. It is proved that the principles and methods discussed here can be used forIBM-PC to communicate with MCS-51.
