[tinyAVR][interrupt question]

[eng_boody]

if i set my External interrupt to rising edge to do some ISR, then i pressed the button triggering that
rising edge , if i keep the key down after pressing it .... will it continue service routine and return back to the original while loop in case am still holding the key down and not let it up yet ?

thanks

Hi,

Isr can be edge triggered or level triggered.

If you press a (debounced) button that is edge triggered it will run the isr exactely once.

If it is level triggered it wil run as long as the button is pressed. Many times.
