I am making an project where I would implement a start button.
My plan was to initialize everything and the enter a while loop waiting until the button was press with code like this:
And then having a interrupt changing START=true;
The problem is I can see the interrupt routine is called, but the program doesn't leave the while loop. I have tried to turn on a LED in the interrupt routine and the read the output pin afterward but that doesn't work either.
I have isolated the problem to this archive, where i have placed an LED in port 1 to GND and uses Port 15 as button by pulling it low.
pressing the button should turn on the LED.
Any working solution for a button will be appriciated, but a fix or reason to the problem would be nice too
