Codes:

#include<reg51.h>

sbit p=P3^0;  //hour ++++++++

sbit q=P3^1;  //hour

---

sbit r=P3^2;  //min +++++++

sbit t=P3^3;  //min

---

sbit rs=P2^0;

sbit rw=P2^1;

sbit en=P2^2;

 

void delay(unsigned int msec)

{

unsigned int i,j;

for(i=0;i<msec;i++)

for(j=0;j<1275;j++);

}

 

void cmd(unsigned char item)

{

P1=item;

rs=0;

rw=0;

en=1;

delay(1);

en=0;

}

 

void lcddata(unsigned char item)

{

P1=item;

rs=1;

rw=0;

en=1;

delay(1);

en=0;

}

 

void main()

{

int h,m,s,h1,h2,m1,m2,s1,s2;

unsigned char array[]={‘0′,’1′,’2′,’3′,’4′,’5′,’6′,’7′,’8′,’9’};

cmd(0x38);

cmd(0x0c);

cmd(0x06);

while(1)

{

for(h=0;h<=23;h++)

{

for(m=0;m<=59;m++)

{

for(s=0;s<=59;s++)

{

h1=h/10;

h2=h%10;

m1=m/10;

m2=m%10;

s1=s/10;

s2=s%10;

cmd(0x80);

lcddata(array[h1]);

lcddata(array[h2]);

cmd(0x84);

lcddata(‘:’);

cmd(0x86);

lcddata(array[m1]);

lcddata(array[m2]);

cmd(0x8A);

lcddata(‘:’);

cmd(0x8C);

lcddata(array[s1]);

lcddata(array[s2]);

delay(100);

 

if(p==0)   //hour++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

{

h++;

s=-1;

if(h==24)

{

h=0;

s=-1;

}

}

else if (t==0) //min

---

{

{

m–;

}

}

}

}

s=-1;

}

}

cmd(0x06);

}

}

}

}

}
