ID:336397 · 发表于 2018-9-29 09:35

单片机同时实现4位时钟8位小灯闪烁的仿真原理图如下（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<reg51.h>
#include<intrins.h>
#define uchar unsigned char
#define uint unsigned int
/*
sbit p20=P2^0;
sbit p21=P2^1;
sbit p22=P2^2;
sbit p23=P2^3;
*/
void Disp();
void Delay_ms(uint delay);
uchar code LED_Val[10] = {0xC0,0xF9,0xA4,0xb0,0x99,0x92,0x82,0xf8,0x80,0X98};//0-9
uchar data num[4];
uchar data led_point[4]={0xfe,0xfd,0xfb,0xf7};
uchar i,s,m,h,second,jjjj,HHHH,LED=0XFE;
uint ge,shi,bai,qian,display_number,bai1,shi1;
void Disp()
{
qian=display_number/1000 ;
bai1= display_number%1000 ;
bai=bai1/100;
shi1=bai1%100;
shi=shi1/10;
ge=shi1%10;
num[0] = ge;
num[1] = shi;
num[2] = bai;
num[3] =qian;
for(i=0;i<4;i++)
{
P1=LED_Val[num[i]];
P2=~led_point[i];
Delay_ms(2);
P1=0XFF;
P2=~0XFF;
}
}
//////////// /////////////////////////

}
}

second++;

}
}
}
}

Disp();
}
}
