i've been using the int0 for adding a value to a var, i'm using a switch for call the int0.
if i've press the switch seems like the interrupt is executing too many times. I think u didnt concentrate on Key de-bounce U need to compensate on the bounce which happens when u press the key for an interrupt to occur. this should be compensated(called debounce) when u develop the code. U have to impose a suitable delay between the key press and the START your required operation. (or) If ur application suits u can clear the interrupt enable bit of int0 using the ISR of int0. |
