基于项目化教学的键盘接口技术教学设计与实现

摘要

The application system of single chip microcomputers often needs external equipment for data communication and the keyboard is commonly used as a necessary input equipment with strong versatility. This paper is aimed at providing easier methods for students to master the technology of keyboard interfaces by using the project-oriented teaching scheme from four aspects of separate button designs, multi-function button designs with one button, matrix button designs and interrupted matrix button designs.%单片机应用系统经常需要与外部设备数据通信，键盘作为单片机应用系统中常用必备的输入设备，有很强的通用性。本文采用项目化教学方案设计，从独立式按键设计、一键多功能按键设计、矩阵式按键设计以及中断矩阵式按键设计四个方面开展键盘接口技术的教学设计与实现，以便让学生可以较轻松容易的掌握键盘接口技术，以达到良好的教学效果。
