Just be aware that if you're starting with 12V VIN then the regulator is going to dissipate roughly 5W with 700mA out (from your other thread).
Pd = (12V-5V) x 0.7 = 4.9W
Figures that I would hit a roadblock after wiring an ammeter to be able to see current and voltage in real-time. That DC-DC converter under the meters has too much noise on VDD and VSS for stable...
CONFIRMED: Noisy power definitely messes up everything when the PIC tries to compare the "wiper" reading with VDD/VSS, even using two 1K resistors to simulate 50% pot.

Hi,
Here's a short list of Frequently Asked Questions that should be of interest for most beginners. Don't hesitate to read them... they're not going to bite you

Re: New project - MSFS C++ USB interface
Well, the SMPS you used are crap and although they say it is a LM25xx in fact they are just bad copies. Also the caps and inductors are crap too.
Ioannis Today, 21:09I would design my own SMPS and make sure to follow...
