这里提供了一些单片机的实验方面的小程序

#define LEDS6
#include"reg51.h"
unsigned char code select[]={
0x01,0x02,0x04,0x08,0x10,0x20};
unsigned  char code LED_CODES[]={
0xC0,0xF9,0xA4,0xB0,0x99,0x92,0x82,0xF8,
0x80,0x90,0x88,0x83,0xC6,0xA1,0x86,0x8E};
void main()
{
     char i=0;
	 long int j;
	 while  (1)
	 {
	     P2=0;
		 P1=LED_CODES[i];
		 P2=select[i];
		 for(j=100;j>0;j--);
		 i++;
		 if(i>5)
		 i=0;

	 }
