Can't debug my Arduino Nano with Studio 7
Eek!   I imported and built my sketch. Programmed the arduino using my Atmel ICE. Of course the program isn't working, that's why I'm trying to debug.     But when...

Funny how that works....
Working on an Arduino project for a magazine article. Was just about working right, and I decided to make a small change in the program. Now it's completely doing nothing like it'...

PR0 and PR1
In a battery system where you don't want to leave inputs floating, what do you do with PR0 and PR1 if you're not using a crystal? I've just always ignored them, but I wonder if...
