发个流水灯灯程序：

#include<reg52.h>

unsigned char code led[]={0xfe,0xfd,0xfb,0xf7,
                          0xef,0xdf,0xbf,0x7f};

void delay1s()   //延时1s
{
unsigned char i,j,k;
for(i=100;i>0;i--)
for(j=20;j>0;j--)
for(k=248;k>0;k--);
}

 void main()
{
unsigned char i;
P1=0;
delay1s();
P1=0;
while(1){
for(i=0;i<8;i++)  //依次亮
  {
   P1=led[i] ;
   delay1s();
   }
   for(i=0;i<4;i++)   //偶数号灯亮
   {
   P1=led[2*i];
   delay1s();
   }
   for(i=0;i<4;i++)  //奇数号灯亮
   {
   P1=led[2*i+1];
   delay1s();
   }
   }
}

马上要考试，一直都在准备复习考试，所以有段时间没弄了，致歉！！！今天抽空夫学习了下，做了LCD 1602的实验：
