help souce code pic18f452

[fyp]

hi can anyone help me!!!.... Iam doing this project regarding pic18f452. I have to build a program that have a delay of a second, mins and hour respectively. i have done the delay of this three timing but dun knw how to make it wrk at the same time, as u can see nw it can only loop one at a time followed by d next delay by using the break;

So can anybody help me...... nd each individual delays to keep looping as well as all the three delay start at same time.



#include <p18F452.h> /* Inserting full text from p18F452.h */
#include <delays.h> /* This file contains processor specific C */
/* code */

unsigned int i;

main(void)
{

TRISCbits.TRISC0=0; // Set RC2 as output
TRISBbits.TRISC1=0;
TRISBbits.TRISC4=0;
TRISBbits.TRISC5=0;
TRISBbits.TRISB4=0;
TRISBbits.TRISB5=0;
TRISC = 0x00; /* Set all pins on PortC as outputs */
TRISB = 0x00;


//Delay for second
while(1)
{
PORTB=0b00110000;
for (i = 0; i <4 ; i++)
{
Delay1KTCYx(250);
}
PORTB=0b00000000;
for (i = 0; i <4 ; i++)
{
Delay1KTCYx(250);
}
break;
}



//Delay for minutes
while(1)
{
PORTC=0b00000001;
for (i = 0; i < 240; i++)
{
Delay1KTCYx(250);
}
PORTC=0b00000010;
for (i = 0; i < 240; i++)
{
Delay1KTCYx(250);
}
break;
}





//Delay for hour
while(1)
{
PORTC=0b00010000;
for (i = 0; i <1440 ; i++)
{
Delay1KTCYx(250);
}
PORTC=0b00100000;
for (i = 0; i <1440 ; i++)
{
Delay1KTCYx(250);
}
break;
}


}// close for main(void)

You just need one delay loop of one second. Call it, when it returns, increment your counter.
Then you have a counter, when you have 60 seconds, you have a minute, 60 minutes an hour etc.
