通过C语言实现的基于51单片机的几个典型例子

#include<reg51.h>
#define uchar unsigned char
   sbit P0_0=P0^0;
   sbit P0_7=P0^7;
   void delay_nus(unsigned int n);
   void main(void)
 {
   P0_0=0;
	{ 
	  while(P0_7==1)
	   { 
	       P0_0=~ P0_0;
	   void	delay_nms(100);
		 P0_0=~ P0_0;
                void delay_nms(100);
		 P0_0=~ P0_0;
		 void delay_nms(100);
		 P0_0=~ P0_0;
	   }
	 }
   
    void delay_nus(unsigned int n)
{
while(n)n--;
}
void delay_nms(unsigned int n)
{
	unsigned long m;
	m=n*1000; 
  while(m)m--;
}
  }
