基于Proteus的8086和8255A接口实验仿真

8086 and 8255A Interface Simulation Based on Proteus

用Proteus仿真的方式代替实验箱进行微机原理实验教学,能让实验者自己完成整个电路的设计,清晰地了解芯片的工作原理和芯片引脚的作用,实验效果有很大的提升。以典型的并行接口芯片8255A为例,实现一个小键盘,说明Proteus仿真实验教学的基本过程,并给出了详细的电路和相应的汇编程序代码。

For microcomputer principle experiment teaching simulation using Proteus instead of the experimental box, experimenter can complete the circuit design, then it can give experimenter a clear understanding of chip＇s working principle and pin function. The experimental results can get better effect. Taking a typical parallel interface chip 8255A as an example ,design and realization of a small keyboard, it illustrates the basic process of Proteus simulation experiment teaching and gives the detailed circuit and corresponding assembler code.
