8路抢答器设计
基于89C51单片机控制，使用Keil-C编译下载
能实现主持人开始，停止功能，8路抢答，倒计时，倒计时喇叭提醒，功能较好
端口定义可以看代码即可看出-This lecture based on single chip set for the design of vies to answer first 8, required on eight different keystroke vies to answer first signal, and through the LED digital display corresponding pipe poems, vies to answer first success through the leds display. Design with two different plan, which plan by external 74 series a chip interrupt signal, scheme 2 by single chip microcomputer timer interrupt achieve internal vies to answer first.
