fix interrupt in AVR

Fermé

I made this circuit: [url removed, login to view]

And this code: [url removed, login to view]

There's a led in PB1 and a button in PB3. When the button is pressed, PB3 pin change its state from high level to low level, this produces an external interrupt. The code of this interrupt, makes the led turn on for 100ms.

But this code, turn ON the led everytime the button is pressed/released, that means everytime PB3 change its state.

TASK:

I want the led to be turned ON, just when the button is released. (Make this by using interruptions)

Compétences : Programmation C, Microcontrôleur

Hi, You can easily check for the pin (PB3) value in the ISR and if it is high so it is rising edge. Best Regards, Ahmed

buenas, tener delay en el ISR es mala idea, la mejor opción es usar una variable para detectar el cambio y hacer el resto en otra parte del código... incluyendo el filtro para el botón. Puedo solucionar el problema y Plus

hi, solution change this line MCUCR &= ~(1<<ISC01) | ~(1<<ISC00); // Trigger INT0 on rising edge to MCUCR &= ~(1<<ISC01) | ~(0<<ISC00); // Trigger INT0 on rising edge let me know

Hello Salvador, The task looks pretty simple. I think, I cam provide you with correct code my evening. As I see, you use _delay_ms in interrupt routine. This is not good. Interrupr routine should finish as soon as Plus

You can use the interrupt only for turning on, and you can turn off the LED in an infinite loop I'm sorry, I do not speak English
