Here's for the firmware part, looking quite interesting:

For the love of XXX I couldn’t get it to work for me to even test if my setup is wired correctly. At that point I turned to open-source solutions.
Getting away from the not-so-well-working Microchip tools is awesome! \o/
I read through the source code of pslab-desktop, found nothing about initialization sequence in javascript or the .py scripts inside the pslab-desktop directory
Then I go a little deeper found that the pslab-desktop use python script in pslab
Then I modified the python script in the serial_handler.py to print something but found nothing showed up in my terminal. Where did all the stdout redirected?
I've removed the .pyc and tested again, nothing changed.
What shall I do next?
strace -f -F -o /dev/shm/unzip/del/pslab_strace /usr/bin/pslab

1749800 fstat(6, {st_mode=S_IFREG|0644, st_size=15726, ...}) = 0
When will the v6 hardware commercially available? and if so, wil the v5 hardware still be commercially available? I'am in the phase of designing a new testsystem and I have to decide which board to use.

I'm reading the python3.9/site-packages/pslab-2.4.0-py3.9.egg/pslab/instrument/oscilloscope.py and power_supply.py
I'm wondering why the abstraction of the two instruments is totally different, why the oscilloscope command is mainly decoded on the PIC24, but power source code sends commands to control I2C bus directly?
Since I'm using two 2-channel DACs on SPI bus, shall I change the abstraction level of the code?
The best practice of abstraction is not overlay between different layers. For example: layer 1, PSLab, layer 2, instrument(oscilloscope), layer 3, (hardware devices MCP4728, ADC, etc).
