標(biāo)題: 51單片機(jī)交通燈程序加Proteus電路圖
以下為程序：
#include<reg51.h>
#define uchar unsigned char
#define uint unsigned int
sbit RED_A=P0^0;
sbit YELLOW_A=P0^1;
sbit GREEN_A=P0^2;
sbit RED_B=P0^3;
sbit YELLOW_B=P0^4;
sbit GREEN_B=P0^5;
uchar Flash_Count=0,Operation_Type=1;
void DelayMS(uint x)
{
uchar i;
while(x--) for(i=0;i<120;i++);
}
void Traffic_Light()
{
switch(Operation_Type)
{
   case 1: RED_A=1;YELLOW_A=1;GREEN_A=0;
         RED_B=0;YELLOW_B=1;GREEN_B=1;
   DelayMS(2000);
   Operation_Type=2;
   break;
   case 2: DelayMS(300);
         YELLOW_A=~YELLOW_A;GREEN_A=1;
   if(++Flash_Count!=10) return;
   Flash_Count=0;
   Operation_Type=3;
   break;
   case 3: RED_A=0;YELLOW_A=1;GREEN_A=1;
         RED_B=1;YELLOW_B=1;GREEN_B=0;
   DelayMS(2000);
   Operation_Type=4;
   break;
   case 4: DelayMS(300);
         YELLOW_B=~YELLOW_B;GREEN_B=1;
   if(++Flash_Count!=10) return;
   Flash_Count=0;
   Operation_Type=1;
}
}
void main()
{
  while(1)
  Traffic_Light();
}
