这是一个为51系列单片机开发的4*4键盘驱动程序。该驱动程序包括2个文件，使用时将C文件关联入工程，在调用文件前包含H文件即可。本键盘驱动程序具有两个接口函数提供两种扫描方式（阻塞和非阻塞），可以任意定制返回键值，具有防抖动处理，具体使用方法可以参见注释。（本程序在Keil C51开发环境中测试成功，并经过多次实践应用）。-This is a series of 51 MCU development of the 4* 4 keyboard driver. The drive included two documents, the use of paper will be linked into C, the call of documents containing H documents. The keyboard driver has two interface functions provide two scan mode (blocking and non-blocking), it will return to arbitrary custom keys with innovative and handling, the use of specific methods can be found in Notes. (This procedure Keil C51 development environment to test successful, and after several practice application).
