Does get_timer1() conflict with Timer1 Interrupt
PostPosted: Thu Mar 05, 2009 9:59 pm     Reply with quote

Hi,
I found out that my processor has two timers, TIMER0 and TIMER1, but I can use only Timer1 since TOCKI is used for GPIO function.
So can I disable INT_TIMER1 before it needs to check timeout wtih set_timer1(0) and get_timer1() and enable INT_TIMER1 back after checking timeout event is finished?
Code:

#include <16F689.h>
#include <stdio.h>
#include <stdlib.h>

#use delay(clock=3686400, crystal)
#use rs232(baud=115200, xmit=PIN_B7, rcv=PIN_B5)
#fuses XT, NOWDT, PUT, MCLR, NOPROTECT, NOCPD, NOBROWNOUT, NOIESO, NOFCMEN

unsigned int16 x;

#INT_TIMER1
void timer1_isr(void)
{
    set_timer1(0x1F00);    //500ms
    EVENT_1();
}

void main()
{
  setup_timer_1( T1_INTERNAL | T1_DIV_BY_8);
  enable_interrupts(INT_TIMER1);
  enable_interrupts(global);
  while(1)
  {
     disable_interrupts(INT_TIMER1);
     set_timer1(0);
     EVENT_2();
     x = get_timer1();
     enable_interrupts(INT_TIMER1);
  }
}


Thanks.

What happened to putting Timer1 questions all in one thread, rather than
a bunch of scattered posts ?

Since my questions are different about Timer1, I do not want to confuse people. I am sorry about this.
