led流水灯

置顶的意思是这个没搞懂，再研究研究。

我也不知道啥叫流水灯。我做出来的是，D1亮一段时间，然后D1熄灭，D2亮一段时间。。。

是我没有看任何资料自己做出来的，挺有成就感的哈。

#include "reg52.h"

typedef unsigned char u8;
typedef unsigned int u16;

sbit ledD1=P2^0; //P20     
sbit ledD2=P2^1;
sbit ledD3=P2^2;
sbit ledD4=P2^3;
sbit ledD5=P2^4;
sbit ledD6=P2^5;
sbit ledD7=P2^6;
sbit ledD8=P2^7;//P27

void delay(u16 i) //延时函数
{
    while(i--)
    {
        //什么也不做
    };                            
}
void main()
{
         while(1)
         {
             ledD1=0;
            delay(60000);
            ledD1=1;
            delay(60000);

            ledD2=0;
            delay(60000);
            ledD2=1;
            delay(60000);

            ledD3=0;
            delay(60000);
            ledD3=1;
            delay(60000);

            ledD4=0;
            delay(60000);
            ledD4=1;
            delay(60000);

            ledD5=0;
            delay(60000);
            ledD5=1;
            delay(60000);

            ledD6=0;
            delay(60000);
            ledD6=1;
            delay(60000);

            ledD7=0;
            delay(60000);
            ledD7=1;
            delay(60000);

            ledD8=0;
            delay(60000);
            ledD8=1;
            delay(60000);


            
         }

}

我这个好象不对哈，哈哈。

刚根据视频画了一个流水灯的示意图。

代码我再琢磨琢磨

其实改进也很简单，让D7到D2依次亮就可以了。

sbit ledD6=P2^5;
sbit ledD7=P2^6;
sbit ledD8=P2^7;



void delay(u16 i) //延时函数
{
    while(i--)
    {
        //什么也不做
    };                            
}


void main()
{
    
    //D1到D8依次亮
    
    while(1)
    {

    ledD1=0;
    delay(60000);
    ledD1=1;
    delay(60000);

    ledD8=0;
    delay(60000);
    ledD8=1;
    delay(60000);

    //以上的代码就是D1到D8依次亮

    //D7到D2依次亮 

    ledD7=0;
    delay(60000);
    ledD7=1;
    delay(60000);

    ledD6=0;

    ledD5=0;
    delay(60000);

    delay(60000);

    ledD5=0;
    delay(60000);

    ledD4=0;

    ledD3=0;

    ledD3=1;
    delay(60000);    

    ledD2=0;

    ledD2=1;
    delay(60000);


    }


}

两个灯一起亮的流水灯

给自己留了一个作业，当D1到D8的时候灯移动的速度越来越快，而从D8到D2的时候是灯移动越来越慢。
