基于ARM S3C44B0X处理器的PS/2键盘接口的设计与实现

Design and realization of PS/2 keyboard interface based on ARM S3C44BOX processor

基于三星公司的S3C44BOX处理器的嵌入式开发平台,提出了一种用S3C44B0X的通用I/O口和中断源实现与PS/2键盘的接口设计方案,详细阐述了其硬件接口设计和软件设计的步骤,并用C语言编写了软件设计程序,以便移植到其它系统中。

Based on the embedding development platform of S3C44BOX processor developed by Sanxing Company, this paper puts forward the design project of interface with PS/2 keyboard with a common I/O interface of S3C44BOX and interrupt source, introduces in detail the steps of design of hardware and software interface and writes the software design program with C Language so as to transfer it to the other system.
