摘要
本文介绍了键盘的工作原理,设计了基于S3C44BOX嵌入式微处理器的键盘硬件接口电路,研究了键盘程序的工作机制,在此基础上了给出了详细的程序流程图。
Keyboard is considered as the major trend of man-machine interaction technology in the future. So the application of key- board is wider and wider in the modern embedded device. This article introduces the basic principle of the functioning of keyboard. It also shows the design of the hardware interface circuit of keyboard based on embedded microprocessor S3C44BOX and gives a research on the implement principle of keyboard program. Based on the above analysis, flow chart has been given.
