摘　　要：阐述了高职学生难以建立起微机数字量输入输出的端口概念的困难和原因,提出了以Proteus及KEIL为平台,探索模块化数字量I/O通道电路设计与调试的教学思路;整个硬件设计中主要展现了全译码电路的设计过程,方便学生理解端口地址的形成原理,建立端口地址编码与硬件之间的一一对应关系;为后续专业课程的教学打下扎实的基础。提出模块化通用I/O通道电路基本框架,以供实际应用参考。This paper expounds the difficulties and reasons why it is difficult for vocational college students to establish the concept of digital input and output port of microcomputer,and puts forward the teaching idea of exploring modular digital I/O channel circuit design and debugging based on Proteus and keil.The whole hardware design mainly shows the design process of full decoding circuit,so that students can understand the formation principle of port address and establish the one-to-one correspondence between the port address coding and hardware,lays a solid foundation for the teaching of follow-up professional courses.The basic framework of modular general I/O channel circuit is proposed for reference in practical application.
