Responsibility for human safety is a scary thing. In the mid-1980's I worked for a defense contractor. Our main project was building an emulation of the flight control system to be used in an experimental version of the F-16. The purpose of the emulation was to validate the design of the actual flight control system. I'll always remember something our aerospace engineer told us during one of our status reviews:
"This program is of vital importance to the safety of the pilot. The flight controls can operate the plane in an unstable state for performance. If those flight controls fail, the pilot dies 2-3 seconds later."
I could screw up a few lines of code, we would fail to find a design flaw, and someone could die. Scared the piss out of me, and was a factor in my decision to get out of defense work.

You need to make it a bit harder so that it might still be around when I get out of bed.

Yes how many hours difference are you ?

Usually 5 hours behind you (Eastern timezone).

Okay, first of all, I'm super proud of this:
An Andy Warhol rendering of a .22 pistol in original form, and on a three color e-paper display[^]
This is using nearest color matching to convert 24-bit color jpeg (Y'CbCr) to a 3-color device (indexed pixel format - 0:black/1:red/2:white)
I don't have an 8-color display yet, but when I get one and add dithering support to GFX it's going to be fun to load photos into it.
Anyway, the work that went into this, and the thought behind it is why I'm proud of it. It makes a super complicated thing simple - so simple that it's hard to appreciate it unless you had to make it.  I think most of the people that have seen it in the ESP32 forum I haunt don't understand why it's a big deal for color e-ink support.
On the other hand, my graphics library overall has garnered more interest than I ever anticipated so I can't complain.

This looks very impressive!
Can you make the color on my new BOOX Nova3 Color color e-ink reader more saturated per chance?!

Very impressive but MY OCDness wants to know why is it upside down? The label on the ePaper thing is upside down.
I’ve given up trying to be calm. However, I am open to feeling slightly less agitated.

It's the way they mounted it on the board. The actual e-paper display I believe is right side up. It's bloody hard to tell though because I can't find a datasheet for the device.

I experience that a lot. A week of coding, and a 60 second demo of the result. Rarely is there an appreciation of the effort that went into it, simply because the user sees exactly what they wanted working smoothly and simply but they don't have the context to understand the effort that went into achieving that result.

My bread and butter client is an engineer himself so he's easy to work with in that regard. I appreciate him.

Ah yes, I know that feeling well. I liken myself to Michaelangelo when the Pope told him "But I wanted the ceiling painted blue."

I'm not a reddit fan typically but they have an espressif developer who mods that subreddit and he's super helpful and the community is mostly friendly

I'm assuming you found this? >> Little Wire[^]
The download links for Windows 32bit and 64bit seem to work.
Is that what you meant by "way to load it"?

Because it has a break in the default section of a switch statement, which was supposed to exit the enclosing while!

If you can keep your head while those about you are losing theirs, perhaps you don't understand the situation.

My sympathies ... they should have used a different keyword for switch really. "break" makes sense in a loop, but esac might have been a better choice way back when.
