Thread: interruptions help

    interruptions help

    Basicaly i have this code that handle a del light. To change the state of the del i use an interruption. But the thing is no matter if i press the button to turn off the light it does not work.
    I think that may be it is due to the way i initiate the interruption.
    here the code
    Code:
    ISR(INT0_vect)
    {
     // here i put the code to change the state, it is just an if else 
     
    }
    i have to use MCUCR register does any one know how it works? i mean if i need to assign it a value what is the best way to do it?
