I want to change Variable state( 0->1 or 1->0) when I push the button.
I was searching for example relating to the GPIO.
but I did not find that i want.
Everything is a timer example
I would like to implement a function that operates when just press a button(using a interrupt).
You can do the advice would be appreciated.
I'd like to get help on how to implement.
What should I do?
I use nrf51822-DK and small button.
