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.
Re: New project - MSFS C++ USB interface
I had 2 options originally:
Demon Today, 23:27- stay under 500mA and use USB power
- use a wall adapter and add a voltage regulator component.
USB power is no longer an option with the 4 LCDs. I don't have...
