流水灯.c

用verilog实现流水灯

/*** P1口接8个发光2级管（LED）,编写程序，使这8个LED轮流被点亮-----流水灯效果   ***/
#include <reg51.h>

Delay() //延时
{
	int counter1,counter2;
	for(counter1=0;counter1<255;counter1++)
		for(counter2=0;counter2<100;counter2++)
			;
}

Circle()//循环
{
	unsigned char value=0x01;//设置要点亮的灯为第一盏
	unsigned char counter=0;
	//初始化P1口
	P1=0x00;
	while(1)
	{
		for(counter=0;counter<8;counter++)
		{
			P1= value;//点亮一盏灯
			Delay();
			P1=0x00;//全部熄灭,消除影响
			value=value<<1;
		}
	}

}
void main()
{
	Circle();
}
