摘要
分析当前PS/2键盘应用背景和优越性,在PS/2标准键盘协议的基础上,应用当前热门嵌入式实验开发平台,设计PS/2键盘具体的硬件电路和驱动软件,研究键盘中汉字输入法实现过程及其扩充方法,总结PS/2键盘及汉字输入法到具体项目应用的工程经验,最后提出键盘的应用和改进.
The background and advantage of PS/2 Keyboard application are introduced.Based on the PS/2 interface protocol on the basis of embedded system,the driver program of keyboard is designed,the special method to design the hardware and software of PS/2 interface is studied,the process of Chinese characters input and its display on the terminal are researched.Finally,the application and its improvement of the PS/2 interfaced in a specific program are given.
