The Design and Realization of Double SCM Machine Communication Based on Embedded Virtual Experiment Platform

针对高等院校传统单片机实验系统中存在的硬件成本偏高及仿真难以实现等问题,研究了一种基于新型嵌入式系统仿真软件Proteus+Keil C的仿真平台。该平台从软、硬件上对单片机等嵌入式系统的设计进行仿真,对单片机双机通信原理进行了分析,实现了51单片机的串行双机通信。结果表明,利用嵌入式虚拟实验平台进行教学,成本低,效率高,仿真效果直观,在高校嵌入式系统实践课程中有良好的应用价值。

There are usually some problems in the tradi- tional SCM experiment system, such as high hardware cost and simulation difficulties. A new simulation platform based on new embedded system simulation software called Proteus and Keil C is researched to solve this problem. In this plat- form, the design of embedded system such as SCM is simu- lated, the principle of double SCM machine communication is analyzed, and the serial communication between double 51 single-chips is achieved. It is concluded from the experi- ment that by using the embedded virtual experiment plat- form during the teaching of embedded system, low cost, high efficiency and visual simulation result can be gotten, and good use value can be achieved in the practice course of embedded system in colleges.
