3、etary,Ministersand摘要随着电子技术的发展和微处理器技术的应用，带有单片机的智能型测控系统的应用越来越广泛，多个单片机系统之间数据传输已经应用于工业、科研、农业等领域，而单片机之间的数据通信最常用的就是串口通信方式，串口通信可以在使用一根线发送数据的同时利用另一根线接收数据，使用简单且能实现远距离通信。本文介绍了一种单片机多机通信的设计方法，主机与从机之间通过串口实现通信，主机通过按键来选择要进行通信的从机，然后通过数字矩阵键盘控制从机的数码管显示数字0-9，同时该从机可以通过按键
4、控制主机连接的LED灯亮灭，实现全双工通信。本文介绍的方法简单易懂，通过仿真基本上实现了上述功能，操作简单，性能稳定，可广泛应用于各种多机通信系统中。关键字：单片机；多机通信；串口；数码管；LEDotherstaffoftheCentre.Duringthewar,ZhuwastransferredbacktoJiangxi,andDirectorofthenewOfficeinJingdezhen,JiangxiCommitteeSecretary.Startingin1939servedasr
