流水灯（51单片机）

单片机 STC 89C52RC
功能
向一个方向流水三次，然后全亮，几秒钟后继续流水
代码

#include "reg52.h"

typedef unsigned char u8;
typedef unsigned int u16;

sbit LED1 = P2^0;
sbit LED2 = P2^1;
sbit LED3 = P2^2;
sbit LED4 = P2^3;
sbit LED5 = P2^4;
sbit LED6 = P2^5;
sbit LED7 = P2^6;
sbit LED8 = P2^7;

void delay_10us(u16 ten_us)//ten_us = 1时，大约延时10us
{
	while(ten_us--);
}
void main()
{	u8 i;
	while(1)
	{
		for(i=0;i<3;i++)
		{
		  	LED1 = 0; //点亮
			delay_10us(5000);
			LED1 = 1; //熄灭
			delay_10us(5000);
	
			LED2 = 0; //点亮
			delay_10us(5000);
			LED2 = 1; //熄灭
			delay_10us(5000);
			
			LED3 = 0; //点亮
			delay_10us(5000);
			LED3 = 1; //熄灭
			delay_10us(5000);
	
			LED4 = 0; //点亮
			delay_10us(5000);
			LED4 = 1; //熄灭
			delay_10us(5000);
	
			LED5 = 0; //点亮
			delay_10us(5000);
			LED5 = 1; //熄灭
			delay_10us(5000);
	
			LED6 = 0; //点亮
			delay_10us(5000);
			LED6 = 1; //熄灭
			delay_10us(5000);
	
			LED7 = 0; //点亮
			delay_10us(5000);
			LED7 = 1; //熄灭
			delay_10us(5000);
	
			LED8 = 0; //点亮
			delay_10us(5000);
			LED8 = 1; //熄灭
			delay_10us(5000);
		}
		LED1 = 0;
		LED2 = 0;
		LED3 = 0;
		LED4 = 0;
		LED5 = 0;
		LED6 = 0;
		LED7 = 0;
		LED8 = 0;
		delay_10us(50000000);
		delay_10us(50000000);
		delay_10us(50000000);
		delay_10us(50000000);
		delay_10us(50000000);
		delay_10us(50000000);
		delay_10us(50000000);
		delay_10us(50000000);
		delay_10us(50000000);//延迟熄灭时间
	}
}

实验结果
功能基本实现，但是led灯不是同时熄灭，需要进一步改进，延时时间可以改动的
