基于51单片机的带时间显示和紧急控制的交通灯的设计。 此程序在硬件上调试通，用定时器1延时，外部中断0接紧急控制，R0为100MS延时常数，R2为状态延时常数，8279控制数码管显示时间,用P1口控制双色灯-With 51 single-chip based on the time display and the emergency control of traffic lights design. On this process in hardware debugging pass, with one delay timer, external interrupt 0 then the emergency control, R0 for 100MS constant delay, R2 for a state of constant delay, digital 8279 control display time control using two-color lights I P1
