51的4*4键盘驱动当按键按下时返回一个值，且只在按下键时返回一次该值，之后返回0；无按键时返回0；包含消抖功能，在键盘的下降沿触发。 基于keil平台-51 4* 4 keyboard driver when the button is depressed to return a value, and press the button only once the value to return, followed by return 0 no keys to return 0 contains extinction Buffeting function, the falling edge trigger at the keyboard. Keil-based platform

这段程序是用在一款七彩灯红外遥控解码程序里,单片机使用PIC12F629,软件模拟三路PWM输出驱动红绿蓝LED分八组共24个LED,实现单LED渐明渐暗,两LED一明一暗,七彩等九种花样.有断电记忆功能.如下是解码程序.-This procedure is used in a colorful light infrared remote control decoding procedure, the single-chip using the PIC12F629, the software simulation of three-way PWM RGB LED output driver in eight groups of 24 LED, single LED gradually dimming out, First one out of two LED dark, colorful patterns, such as nine. have power memory function. decoding procedure is as follows.
