原理圖：

單片機源程序如下:

#ifndef _DEFINE_H_
#define _DEFINE_H_
#include <intrins.h>
//定義數據
unsigned char Seg_Yang_Led_Table[]={0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90,0x88,0x83,0xc6,0xa1,0x86,0x8e};
//定義函數
void Delay1ms() //@11.0592MHz
{
unsigned char i, j;
_nop_();
_nop_();
_nop_();
i = 11;
j = 190;
do
{
while (--j);
} while (--i);
}
