main.c

单片机的仿真实例!用的是Proteus作的,大家有需要的尽管下吧

//#include <stdio.h>
#include <io51.h>

unsigned int temp1;

void delay(unsigned int temp)//延时程序
{
  while(--temp);
}




int main(void)
{

        P2=255;//led is off
                while(1)
		{
                        P2=0XFE;
			temp1=35000;
			delay(temp1);

			P2=0XFD;
			temp1=35000;
			delay(temp1);

			P2=0XFB;
			temp1=35000;
