considering making some sort of overcomplicated assemblies that have the possibility of making some very cool lighting things.

My only use of python these days is as a calculator in my shell, but you gotta support people doing the right thing.

80 boards, each one with 10W of LEDs (98 RGB LEDs), in rs-485 clusters of 20+1, with 4 RP2350s taking it back to a PC.

The goal is to make something like this HD44870 LCD screen, except 1.8m wide and 0.6m tall, a cooler font, and have it use an offensive amount of power to be a giant wall sign in my office.

Okay so what if I made 16x9cm panels, that each have 14x7 RGB LEDs (98 total), on a 1-sided aluminum PCBA, and used one or two FR4 1.6mm black PCBs as a light guide, with dark diffuser plexi on top, so that each panel could render a departuremono.com char, and I can make a giant 4x20 char display?

Yeah, tbf, *I* think this is very clear, but I also like doing sicko stuff, especially with turbofished methods that take bundled traits like the Endpoint here :D
You can also write much less noisy Rust in most cases, for sure.

Embedded development is great because you'll have a datasheet that has multiple diagrams and sections about the wonderful PLLs, and how you can use them to flexibly divide your clock sources, wow, they are so great, here's how to use them, and then have one little "Note" that says "don't use this".

Sometimes you sit down for two hours to plan out more of your weird but technically elegant hierarchical addressing scheme, and you only end up with a single diagram that took two hours to come up with and draft into a usable diagram.
To be fair, I think it's going to be very useful for later prose

NXP just gives you three pages of a PDF and a LOT of register definitions with *about a page* of what to do to bring up the clocks, and then a STACK of register definitions 🙃

Compare to an stm32h7, which has very similar fundamental blocks, but still a very different topology!

Honestly, it's funny how close this is to the classic "Monokai" color palatte (which I use for everything that isn't black/white). The biggest difference is Red vs Pink, and the monokai colors are a bit more fluorescent.

I'm pleased to announce: it's gumbo season again. My kitchen is full of steam and good smells, and the first roux went quick and without issue :D

The Rust Zulip has a `:lolsob:` emoji I hadn't seen before, and it's too perfect. Apparently my wife's work has it in their Slack too.

ooh, this would be fun for MCUs too, I ended up annotating this in text using rp2350a.pinout.xyz, which always has room for annotation errors, and I always end up double/triple/quadruple check

I'll be speaking at Rust China Conf/Rust Global China this weekend to talk about Ergot, my messaging library for embedded systems in Rust!
Details and speaker list here: rustcc.cn/2025conf/, lots of familiar faces, excited to meet up with folks!
