本文以二台TP-801单板机为环境,介绍一种具有实用价值的主从式双机系统的通讯技术,并简要叙述了硬件连接及通讯程序的设计方法。一些廉价的实时控制系统,往往存在着存贮量不足及运算速度不高的问题。在这种情况下,通过主机的一个并行接口(如Z80系列的PIO)拓展一个子系统——“秘书系
In this paper, two TP-801 single board machine environment, introduces a practical master-slave dual-system communication technology, and a brief description of the hardware connection and communication program design. Some cheap real-time control system, there is often the problem of insufficient storage capacity and computing speed is not high. In this case, a subsystem is expanded through a host of parallel interfaces (such as the Z80 series of PIOs) - "Department of the Secretary
