Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Working on some updates for the code, been busy recently but now have some time available. One update I need to get done is the current limiting, Mark has been waiting patiently for a long time for that.

Mark has also had buzzing problems when the regulator is at 50% or less. Inserting the following line

"TCCR0B = TCCR0B & B11111000 | B00000010; // for PWM frequency of 7812.50 Hz"

After void setup as per below.

void setup() {
TCCR0B = TCCR0B & B11111000 | B00000010; // for PWM frequency of 7812.50 Hz

This will multiply the PWM frequency by 8 from the present 976.56 Hz.

@noneyabussiness I never got to the bottom of why the 2 channels linked together caused the MOSFETs to short but separating them has worked flawlessly since December 2017 so I have not wasted any more time on it. I am reluctant to link the 2 channels together in the GTI as that is how it was in the regulator.

If have 1 working and 2 fualty Aroura's they have an internal problem that causes it to show low resistance to ground error. If you have a fix for it I am all ears.

There are only 10 types of people in the world: those who understand binary, and those who don't.
