仿真原理图如下（proteus仿真工程文件可到本帖附件中下载）
单片机源程序如下:
#include <reg52.h>
#include <intrins.h>
#define uchar unsigned char
#define uint unsigned int
//延时函数ms
void _delay_ms(uint i)
{
uchar j;
for(;i>0;i--)for(j=0;j<120;j++);
}
//模式变量数组
uchar mo1[]={0x00,0xff};
uchar mo2[]={0x01,0x00,0x02,0x00,0x04,0x00,0x08,0x00,0x10,0x00,0x20,0x00,0x40,0x00,0x80,0x00};
