AD_count_countdown
说明: 设置3个功能键:当某一功能键被按下后,进入相应的功能模式。3个功能有:
1)8路数据采集功能:通过调节可变电阻实现0-5V的电压输出作为8路输入信号使用,每路信号用2位LED显示采集的结果。报警:任意一路超过某一门限(可自己设定)时,发出报警(声音+灯闪烁,并通过灯指示是哪一路报警),同时停止采集。2)计数功能:利用计数功能键,实现每按一次按键,LED显示加1,从0-99计数。3)秒表功能:只用一个键控制。按下一个按键后时钟启动,从零开始计时,计时间隔0.01秒,再按一次后停止。再按一次后清零。如此循环。
本设计采用2个MAX7221串行驱动2个8路数码管显示,更节省单片机I/O口。(AD、count、countdown)
