Please help me with stepper motor If you are seriously putting AC (Alternating Current?!) into the center taps of your stepper motor windings, it's a miracle you haven't had a cheerful 'boom!' yet.

What else would you call a trace with nothing on the other end? S.

Optimal width for long signal traces? A 12" trace with nothing on the other end is an antenna. You should expect it to radiate (poorly) and resonate (likewise). S.

bizzaro interrupt behavior What baud rate are you using for the UART? See if blinking an LED will do instead - I'm thinking what takes 45ms is your UART notice. Just an idea - oh, and I'm sure...
