buzzer routine

Posted: Sun Jan 09, 2011 2:27 am

Hey guys below is my buzzer routine.
I wrote this routine to set "PIN_B1" high every 2 seconds for 300ms
and then set it low again.
But the problem here is that the pattern is not synchronized, the "ON" time keeps on decreasing and again gets normal.

Code:

//-------------------------------------------------------------------------------------
#INT_TIMER1
void Timer1(void)
{
set_timer1(TMR1RESET);
ticker_2++;
ticker_buzzer++;
if(ticker_2>100){
   ticker_2=0;

   buzzer_time++; --------->counting seconds.
      }
if(ticker_buzzer>10){
   ticker_buzzer=0;
   buzzer_time_on++; ------------------>counting 100ms
      }
}
//-------------------------------------------------------------------------------------
void buzzer(void)
{
if(inv_on){
if(buzzer_time==2){ -------->2 seconds
   buzzer_time=0;
   output_high(PIN_B1);
}

   if(buzzer_time_on==3){ ----------------->300ms
      buzzer_time_on=0;
      output_low(PIN_B1);
   }
}
}
//-------------------------------------------------------------------------------------

Thanks.
