Richard,

I would do something like this (again in MikroC):

// declare a couple of global variables
// the scope must make them persist in both Interrupt and main
Char counter, second_flg =3D0;

//Timer1
//Prescaler 1:8; TMR1 Preload =3D 3036; Actual Interrupt Time : 100 ms
=20
//Place/Copy this part in declaration section
void InitTimer1(){
  T1CON	 =3D 0x31;
  TMR1IF_bit	 =3D 0;
  TMR1H	 =3D 0x0B;
  TMR1L	 =3D 0xDC;
  TMR1IE_bit	 =3D 1;
  INTCON	 =3D 0xC0;
}
=20
void Interrupt(){
  if (TMR1IF_bit){=20
    TMR1IF_bit =3D 0;
    TMR1H	 =3D 0x0B;
    TMR1L	 =3D 0xDC;
    //Enter your code here
	counter =3D counter + 1; if(counter > 9){counter =3D 0; second_flg =3D
0xff;}
  }
}=20

void Main{
	InitTimer1();
	turnOnPin(); // replace this with your actual code
	do{
		if(second_flg){
			TMR1IE_bit	 =3D 0;
			TMR1H	 =3D 0x0B;
			TMR1L	 =3D 0xDC;  // reset the timer for the next
round
			turnOffPin();  // again do this your way
			second_flg =3D 0;
			delay_ns(20);
			turnOnPin();
			TMR1IE_bit	 =3D 1; // and do it again
		}
	}while(1)

}
