This is signature matter.

Is this kind of like have a default configuration (code path, etc.) and one that is what most people use (what you already coded for)?

I'm not sure.
The problem is every other driver supports two operations - fill a block of pixels with a single color, or fill a block of pixels with bitmap data.
I can do that with the RA8875
But the RA8875 hardware also has hardware accelerated line drawing, font drawing, shape drawing, etc.
My library only knows about the two operations i mentioned at first.
And to my knowledge the RA8875 is the only hardware on the market for IoT gadgets that does this (i won't stake a betting claim to that, but so far it's the only one I've seen)

Had one of those "it works on my machine" moments today, monday morning of course.
Used Process RedirectStandardError to get error output of 7z.exe, something like described here:
ProcessStartInfo.RedirectStandardError Property (System.Diagnostics) | Microsoft Docs[^]
Everything worked perfectly fine on my development machine. Put the exe on a test machine and ... hang.
Had to resort to not using StandardError.ReadToEnd() and only reading a small part in a char[] buffer to get it working

I wish I had worked with you this morning. I routinely code around that when doing process automation this way. I've run into it enough times that it's reflex. I even have some code around here on codeproject for it ... ah shoot it doesn't do what i remembered.
Oh well, here's a task wrapper around process capturing Adapting Event and Callback Based Asynchronicity to the Task Framework[^]
It's short and sweet.
Anyway, yeah you can't do things like ReadToEnd()... you have to buffer, but i almost always do reads incrementally so while I don't tend to code that way, i try to make my callable surface area as friendly as possible for something that does. Still, there's only so much you can do for that problem.
ReadToEnd() is a bad idea for a few reasons, some of which are circumstantial but some of which is that it can surprise you as it did here. Don't expect it to be better behaved on NetworkStream either, necessarily. It's easy as long as it works. When it doesn't it's monday.

Write an adapter for that device class that uses the original code / library as a component (composition versus inheritance).
I have dll's that call other dll's.

So to make it clearer, I have a graphics library called GFX
It does not know a thing about video hardware. It's strictly standard C++ with no libraries other than stdlib
Then, I have drivers. Drivers expose a few members that can be called by GFX.
These members don't account for line drawing and such. They boil down to "fill rectangle with this color" or "fill a rectangle with this bitmap"
In order to take advantage of specific features of this device, like hardware line drawing, I need to redesign that layer/interface between the drivers and GFX.
Seems like a no brainer except this is the only device out there that has the hardware line drawing and such. Nothing else does. And it's not even a common display. That sort of makes me not only not want to bother, it almost makes me want to actually avoid it.

I would avoid adding more for that device until you absolutely have to use its acceleration. Consider it a mutant and move on, for now. That is, if you have other, higher priority things to address.

Part of me agrees. There's a big part of me that feels like it's a cop out though, especially since I'm stalled on my paying work until I get a prototype that I need from my client.

It's not a cop-out to say that you don't support some feature. That goes in the future enhancements bucket to be prioritized along with everything else.

I ended up going this route, and punting the hardware acceleration. Since then I've added directX support, but it's strictly for prototyping on a PC because it is S-L-O-W due to the "polarity mismatch" between DirectX and GFX at the "driver" level. Line Draw acceleration and stuff would help there too.

Nice clue but population is a bit tentative for natives - just sayin

Blimey... I've got nothing, so better make sure I solve it tomorrow so it doesn't come back to me...
