Hi Friends,

In hurry I missed copying some lines of my ISR. These lines I couldnt see because of a lot of commented stuff around them Here are the correct ISR.

/*********Interrupt function for timer 1****************
This interrupt is always on and is 100us*/
void t1_isr(void) interrupt 3
{
	SYSTIME++;			//increament the SYSTIME variable used for fire timing
	if (SYSTIME>firedly && firecount  && ttbit && onfire)
	{
		FIREPORT=!FIREPORT;	//Put the fire pulse	
		firecount--;		//Reduce remining pulse counter.
	}
	else
		FIREPORT=1;		//Make fire pin 1 to keep transistor off.

	ttbit=!ttbit;			//fwbit to make firing pulse 200us
}

/*ISR for PCA modules 0 This interrupt is always ON*/
void cf_isr(void) interrupt 6 using 2
{
		TR1=0;
		TF1=0;
		TL1=0x7c;				//system timer ticks once 100us.
		TR1=1;
		firecount=6;	//set 6 pulses to be sent.
		fwbit=!fwbit;
		if (fwbit)		
			cycles++;	//Increament cycles every 2 half cycles.
		ioport=OPSTATUS;	//Refresh Output ports.
		SYSTIME=0x00;		//Reset SYSTIME variable.
		CCF0=0;			//clear the interrupt flag.
}

Thanks & Regards,
