Intergral Windup method in PID control
So during heating from cold. The proportional term could become very high so you should clamp at 100% The integral term rises high so it's clamped at 100%   Perhaps try to...

Can someone help me understand assembly instructions for setting DIRSET?
I think your avr-objdump is broken. According to Atmel-0856L-AVR-Instruction-Set-Manual; STS is always a 32-bit instruction, whatever kind of AVR.

Digital output vs Vcc
You didn't tell us, but as the post is tagged Arduino; let's assume ATmega328P.   Apart from having to extrapolate from 3V to 2.7V; what does this graph on datasheet Pg608...

Power Changeover Switch - Ingenious Circuit Needed
It's overkill but you could use separate switching regulators, each with their own logic level enable signal. You could then use the code in #2 to drive those enables.

ADC78472 chip control by GPIO of Atmega128A
Here's a couple of things to put right on Monday morning:   Do your bit-banging all in one place instead of distributing it between the ISR and main(). So the ISR becomes...

ADC78472 chip control by GPIO of Atmega128A
Your use of two linked breadboards is the problem.   You have enough room lengthwise to rewire the project to use a single breadboard. Then the micro-controller and ADC can...
