code for digital clock using ds1307+pic16f877a+lcd

digital clock using pic16f877a

pls send me the code for digital clock(calender)using pic16f877a,ds1307and lcd.i am using mplab ide and hi-tech c compiler

a simple clock using ds1307 + pic16f877a

Hello!

Any other request?
I guess you also want it ASAP, you need source code with useful
comments, and with complete documentation?

Dora.

i need the program for digital clock using pic16f877

Dear friend,

Here i post a code for digital clok using pic16f877a,ds1307 and 2*16 lcd.Here i use MikroC.

char sec,minu,hour,day,month,year,date;

char m1,s1,h1,d1,dt,y1,mo1;
void write()
{
// I2C_Init(100000); // initialize full master mode
Lcd8_Out(1,1,"write");
I2C_Start(); // issue start signal
I2C_Wr(0xd0); // address DS1307
I2C_Wr(0); // start from word at address (REG0)
I2C_Wr(0x80); // write $80 to REG0. (pause counter + 0 sec)
I2C_Wr(0); // write 0 to minutes word to (REG1)
I2C_Wr(0x12); // write 12 to hours word (24-hours mode)(REG2)
I2C_Wr(0x05); // write 5 - Thursday (REG3)
I2C_Wr(0x25); // write 25 to date word (REG4)
I2C_Wr(0x09); // write 9 (September) to month word (REG5)
I2C_Wr(0x08); // write 08 to year word (REG6)
I2C_Stop(); // issue stop signal

I2C_Start(); // issue start signal
I2C_Wr(0xD0); // address DS1307
I2C_Wr(0); // start from word at address 0
I2C_Wr(0); // write 0 to REG0 (enable counting + 0 sec)
I2C_Stop();

}
void read()
{

Lcd8_Out(1,1,"read");
I2C_Start();
I2C_wr(0xD0);
I2C_wr(0);
I2C_Repeated_Start();
I2C_wr(0xD1);
sec=I2C_Rd(1);
minu=I2C_Rd(1);
hour=I2C_Rd(1);
day=I2C_Rd(1);
date=I2C_Rd(1);
month=I2C_Rd(1);
year=I2C_Rd(0);
I2C_Stop();

}
void display()
{
LCD_Out(1,1,"display");
s1=Bcd2Dec(sec);
Lcd8_Chr(2,7,(s1/10 +48));
Lcd8_Chr(2,8,(s1%10 +48));
Lcd8_Out(2,6,":");

m1=Bcd2Dec(minu);
Lcd8_Chr(2,4,(m1/10 +48));
Lcd8_Chr(2,5,(m1%10 +48));
Lcd8_Out(2,3,":");

h1=Bcd2Dec(hour);
Lcd8_Chr(2,1,(h1/10 +48));
Lcd8_Chr(2,2,(h1%10 +48));

d1=Bcd2Dec(day);
Lcd8_Chr(1,5,(d1/10 +48));
Lcd8_Chr(1,6,(d1%10 +48));
Lcd8_Out(1,11,"/");

dt=Bcd2Dec(date);
Lcd8_Chr(1,9,(dt/10 +48));
Lcd8_Chr(1,10,(dt%10 +48));

mo1=Bcd2Dec(month);
Lcd8_Chr(1,12,(mo1/10 +48));
Lcd8_Chr(1,13,(mo1%10 +48));
Lcd8_Out(1,14,"/");

y1=Bcd2Dec(year);
Lcd8_Chr(1,15,(y1/10 +48));
Lcd8_Chr(1,16,(y1%10 +48));
}
void main()
{
trisc.f4=0;
trisc.f3=0;
Lcd8_Config(&portc,&portb,0,2,1,7,6,5,4,3,2,1,0);
Lcd8_Out(1,1,"start");
Delay_ms(1000);
I2C_Init(100000);
write();
while(1)
{

read();
display();
}
}

Andd...here we have the sponsor......Just posting the code will do nothing. Guess the OP will ask for Complete description of the code, Flow charts, PCB layouts, and project description too. Be ready for that too.

Celebrating with bottles of Champagne...Cheers

If you have PROTEUS simulation software with you ,it has the same project what you want in its example/sample projects.

Jerin.
