Oh hey now #rustembedded could work.
Think there's enough Rust Embedded folks out there to justify setting up a feed? 👀

Spent the last two weeks swapping out the PCB (top right, based on RPi Pico2) and expanding the user workflows of the interface. Firmware on the Pico2 as well as the interfacing software are written in Rust. The actual interface is based on Slint @slint.dev.

The __cortex_m_rt_main_trampoline in Rust embedded sets up the stack and jumps to __cortex_m_rt_main, ensuring proper init. It saves r7 & lr for debugging. In GDB, skip it and set a breakpoint at 0x686 for the real main logic. #RustEmbedded #GDB #ReverseEngineering #Rust

I'll be wandering around today (Thursday) near the convention center, so if you want to go for a walk or grab a coffee or beer and talk about [embedded] Rust, let me know! My DMs are open, and we can figure out how to meet up! Oh, and I have @rustembedded stickers! 2/3

And with that, @OxidizeConf is wrapped up. Thank you everyone who helped organize, speak, or attended. This was an incredible week, and I can't wait to see you all again soon.
Now I need to sleep for the next week, then to work on some interesting things for @rustembedded...

I've been blinking a lot of lights lately. The next set of lights are going to be for a dog collar for Kuma :)
First demo using the ThunderPack from @jgillick, with a strip of 30 silicone'd WS2812Bs.
(Moderately) high powered @rustlang/@rustembedded, of course :D

I had to go digging in some CircuitPython, but I have basic Row/Column scanning working already! Just outputting keypresses for now via @FerrousSystems' `defmt` logging

Progress! Ported my Sparkfun 7-seg crate from SPI to I2C, and we have a basic hello world in @rustembedded.
Also a beautiful LEGO housing built by @lauraemunns, with room for some LEDs and a speaker grille
Now to get the DS3231, SCD30, and maaaaaaybe the e-paper display working

Managed to get Keyberon and USB working on the @makerdiary M60 w/ @rustembedded!
Basic typing works (with fancy colors), and I added an overlay to change the number keys to F-keys, and add an arrow pad (with pgup and pgdown).
When you activate the overlay it lights up the keys!

Aw yeah! My @rustembedded I2C bootloader works!
In this video, I:
* Boot to the current app
* Reboot while holding buttons to go into bootloader
* Flash over I2C from the STM32F4
* New image boots
* Do another power cycle, still second image!
Now to clean it up a bit 🥳🥳🥳

Published and documented the color sequencer crate that I've been talking about lately (with the pretty patterns and goofy markdown macro tables), give it a look if you like making fun blinky @rustembedded things!

Doing this check helps out people working in @rustembedded, @rustwasm, and other "odd" environments where we can't rely on having std, but we still like having nice libraries to build with!
Thanks for listening to my rant!

Hey @rustwasm folks, do you know who implemented the CI tests in the rust-lang/rust repo? Git blame says it was @alex_crichton, but I was wondering if anyone else was involved. Context: https://github.com/rust-lang/rust/issues/52163 - It would help out @rustembedded a lot :D

TIL the term "Typestate Programming". Sort of like the builder pattern, this is what lets us do a lot of cool shenanigans in the @rustembedded world when interacting with hardware.

@japaricious and @therealjpster, I've had an idea.
If we can trick @steveklabnik into using the Monotron as his primary #rustlang development machine for a year, just think of all of the support @rustembedded would get!
Can you make an IRC client yet JP? Maybe an SSH terminal?

Informal Poll: Would you be interested in attending a @rustembedded summit, Early 2019 in Berlin?
The idea would be to have a space to discuss/work on #embedded @rustlang topics (think all-hands/Impl period) for a few days, also maybe with some workshops/talks
RTs appreciated!

Idea for #svd2rust in the @rustembedded space: have a `--mock` mode, which generates a peripheral access crate where all reads/writes aren't to a fixed memory address, but instead a global state table (probably a hashmap with addr as key). Use it for unit testing HAL crates.
