这一程序是用来编流水灯的LCD

#include <reg52.h>
sbit p11=P1^1;
void delay (unsigned char t);
void main()
{
unsigned char k;
while(1)
{
	   k=1000;
	   while(--k)
	   {
	        delay (500);
	   }
	   p11=1;
	   k=1000;
	   while(--k)
	   {
	       delay(500);
	   }
	   p11=0;
}
}
void delay(unsigned char t)
{
	while(--t);
}
