Hi. I'm reading your code, trying to adapt it for my needs. Can you explain why do you read Vref in a separate injection group? What difference does it make compared to measuring both channels in the rule group?
Is it to read Vref on separate timer trigger after HVMON channel is converted?
Also I am reading the reference manual and there is this note:

Note: 1. When converting a rule group or injection group in intermittent mode, the conversion sequence does
not automatically start from the beginning when it ends. When all subgroups have been converted, the next
trigger event starts the conversion of the first subgroup.
2. You cannot use auto-injection (JAUTO=1) and intermittent mode at the same time.

So does it mean that Vref is being read 2 times in a row?
Also this line:

Sorry if it's annoying, I am just confused "a little" :)

Hi,

I saw this pop up on my YT feed - very interesting and love the concept of an addressable PWM driver for nixie tubes.

I actually have a small stash (now 14; I had 20 in total, but already built a clock using an off-the-shelf board which requires 6) of IN-17 tubes which are a bit smaller (and IMO way cuter 😉) than the IN-12 you've used.

So, could the design be altered to suit the footprint of the IN-17? And is it electrically compatible?

Hi there, just came across your videos on youtube.

Since you released the rv0003usb library after this project was "complete" I thought it might make sense to use that here, if possible (note that I have not looked at the code thus far and I am not sure if for example the pid control loop and usb interrupt could interfere with each others timings in some way) and since you mentioned you wish to use this via usb in the video I just thought to at least throw the idea in the room.

Feel free to just ignore/close this if there is no interest in that, just a thing that came across my mind :) ( and certainly don't feel pressured to make any changes here, if I wish to use this I can work on this myself (and create a pr afterwards if desired), again, this is just an idea that crossed my mind )

PMS132B-S08 is $0.05 in quantity at LCSC, CH32V003J4M6 is $0.115
Is the CH32V003 worth twice the price? The PMS132 has a multiply instruction.

What is it about the PMC131-S08A that makes it twice the price of the PMS132B-S08? The datasheet is hard to decipher, I think the PMC has better power noise immunity.

PY32F002AW15U6TR has multiply, $0.104

Hi, I'm using KiCad 5.1.5 on Ubuntu 20.04 and can't open the schematics. Which version you are using? Thanks, nice project!

Hi, Is there anywhere I can buy these driver PCBs pre-made. I would love to get some for my projects

The new cap is a little wobbily. Switch back to the 1210 cap.

Instead of just P.

Hi,
this is not an issue:

I was admiring your flyback driver code and I'd just like to know what the trick you used to divide by a float with only integers here is called:

Would you mind adding a PDF file of the schematic to the repo, please?

First: Use an extra IO pin to soldered header.
