基于MFC的单片机上下位机通信控制系统设计

随着现代信息技术的发展以及计算机的广泛应用,计算机与计算机、计算机与微处理器(MCU)等之间串口通信在数据采集、数据通信、故障检测、工业监控、实时控制系统等方面得到了广泛应用。本文以单片机为下位机,PC为上位机,利用可视化编程软件Visual C++6.0 MFC设计了友好的人机交互界面实现了PC与单片机之间的数据通信,其编程模块化、易于扩展、通用性强,适用于一般的工业控制系统。

With the development of modern information technology and the wide application of computers, serial communication between computers and computers and computers and microprocessors(MCUs) have been used widely in data acquisition, data communication, fault detection, industrial monitoring, real-time control systems, etc. In this paper, the single-chip microcomputer is used as the lower computer,and the PC is the upper computer. The visual programming software Visual C++6.0 MFC is used to design a friendly human-computer interaction interface to realize the data communication between the PC and the single-chip microcomputer. The soft programme is modular,easy to be expanded and strong universal, which is suitable for general industrial control systems.
