如何利用proteus和keil仿真简易交通灯

简易模拟交通灯

1、proteus仿真图

2、要求
东西向绿灯亮10秒，黄灯闪烁3次后红灯亮， 红灯亮后，南北向由红灯变为绿灯，15秒后南北向黄灯闪烁3次后变红灯，东西向变绿灯，如此重复。
3、代码

#include

#define uchar unsigned char
#define uint unsigned int

sbit eastWest_Yellow = P0^1;
sbit southNorth_Yellow = P0^4;

void delay()
{
	uint i;
	uchar j;
	for(i = 0;i < 1000;i++)
	{
		for(j = 0;j < 125;j++)
		{
		}
	
		 
	}
}
void eastWest_YellowAndYellowLight()
{
	uchar i;
	P0 = 0xF3;
	for(i = 0;i <10;i++)
		delay();
	P0 = 0xF7;
	for(i = 0;i < 6;i++)
	{
		eastWest_Yellow = !eastWest_Yellow;
		delay();
	
	}

}
void southNorth_GreenAndYellowLIght()
{


	uchar i;
	P0 = 0xDE;
	for(i = 0;i <15;i++)
		delay();
	P0 = 0xFE;
	for(i = 0;i < 6;i++)
	{
		southNorth_Yellow = !southNorth_Yellow;
		delay();
	
	}


}

void main()
{
	while(1)
	{
		eastWest_YellowAndYellowLight();
		southNorth_GreenAndYellowLIght() ;
	}
}
