how to enable and disable timer1 runtime
PostPosted: Mon Feb 21, 2011 3:27 am     Reply with quote
hi all Smile

here's my code

Code:
 #int timer1
void isr(){
    xxx....xxxx; //expression, to disable interrupt, however this works fine.
}

void main(){
setup_timer_1(clk_internal,div_by_8) // code is not completly accurate but i forgot the actual, because i am very far from now (work)
enable_interrupts(GLOBAL)

while(true){
   if (pin_d1){
                    enable_interrupts(Timer_1)
                  }
}
}



here when i run this code the interrupt is not enabling Shocked ., after a long time of different combinations Embarassed
if i declare enable interrupts like the below it works good Laughing
Code:

   if (pin_d1){
                   setup_timer_1(clk_internal,div_by_8)
                   enable_interrupts(GLOBAL)
                   enable_interrupts(Timer_1)
                  }


is this the correct way to enable the interrupt (timer1 or 0) dyanmically. r am i doing some mistake plz help me Confused

The problem is with your test. PIN_D1, is a constant. If you want to test the value present 'on' the pin, the syntax is "if (input(PIN_D1)) {"

Best Wishes
