测控系统中标准键盘接口设计

The interface design of standard keyboard in control and measure system

通过实例对标准键盘工作原理及其与单片机测控系统的接口做了介绍 ,提供了用C5 1编写的读键函数get-key及应用实例。提供的接口及C5 1函数可直接移植到其他测控系统开发中。

This paper instructs the theory and interface of the standard keyboard in control and measure system with an example. The function for reading keyboard and its example is also afforded in this paper. The interface and function programmed by C51 can be used in other control and measure system easily.
