I’ve created a starter packet for the Embedded Rust community on Bluesky. Reply if you or someone you know should be on this list. go.bsky.app/G3wxTcN

Write embedded drivers without the MCU in your dev loop. Pico de Gallo turns a Pi Pico 2 into a USB-attached I²C/SPI/UART/GPIO/ADC/1-Wire bridge, so your driver is just a cargo run binary talking to real silicon from your laptop. Build one for your chip → balbi.sh/posts/writin...

> **only bounds** are going to be the most impactful change to Rust that you’ve never heard of. This post explores the feature and aims to answer a particular question about the design (the scope of bounds, I’ll explain). smallcultfollowing.com/babysteps/bl...

For all Silicon Labs EFR32 Rust fans I just published crates.io/crates/silab.... It follows the same idea as crates.io/crates/stm32...

This paper finds that Rust on an microcontroller costs you about 10% extra flash space, actually saves you a bunch of RAM, and takes no extra time to deliver (as compared to C). Seems about right - especially as the C version needed a heap and the Rust version did not. arxiv.org/pdf/2604.25679

> Arm and Ferrous Systems bring Rust to Cortex-R82AE, enabling memory-safe, high-performance real-time systems for physical AI Working on this has very rewarding and I can't wait to see what you build on top of these building blocks. developer.arm.com/community/ar...

** Speaker announcement ** Catch Cliff L. Biffle's talk 'Common Pitfalls of Rewriting Things In Rust' at RustWeek 2026! Info & tickets: 2026.rustweek.org/talks/cliff/ See you in Utrecht May 18-23, 2026! #rustweek2026 #rustlang

wanna hear about what it's like teaching Rust in higher education? learn about the embedded scene? the hippy lore of unconfs? all that and more in the interview with Bart Massey! (video below)

🚀 Ferrocene 25.11.0 is out – and yes, it’s open source! Ships our first IEC 61508 (SIL 2)-certified subset of core, enabling certifiable Rust for safety-critical systems across multiple architectures. ⚙️ + updates from Rust 1.89 & 1.90. 🔗 Release Notes: public-docs.ferrocene.dev/main/release...

It's time for the State of Rust Survey! The Rust Project invites you to take this year’s survey, whether you have just begun using Rust, you consider yourself an intermediate to advanced user, or you have not yet used Rust but intend to one day 🦀

🦀 I've improved the implementation behind all the string formatting macros in Rust: println, panic, format, write, log::info, etc. (Everything using format_args!().) They will compile a bit faster, use a bit less memory while compiling, result in smaller binaries, and produce more efficient code! 🎉

“We adopted #rustlang for its security and are seeing a 1000x reduction in memory safety vulnerability density ... with Rust changes having a 4x lower rollback rate and spending 25% less time in code review, the safer path is now also the faster one.” security.googleblog.com/2025/11/rust...

If you do #embedded #Rust on the #rp2040 with elf2uf2-rs, and you struggle with the recent "Unrecognized ABI" error due to a change in Rust's elf header for `thumbv6m-none-eabi`, I've landed StripedMonkey's patch in both Arch Linux and Homebrew, so if you use those packages, things should work […]

Rust 1.88.0 has been released! ✨🎊 🦀 This release brings you let chains, naked functions, automatic Cargo cache cleaning, Cell::update, proc_macro span locations, as_chunks methods on slices, and more! Check out the blog post and release notes for all the details: blog.rust-lang.org/2025/06/26/R...

Really Small Rust by Cliff L. Biffle at RustWeek 2025! youtu.be/NKsPEZzA4XM #rustlang #RustWeek

Today we're switching the bzip2 crate from C to 100% rust: trifectatech.org/blog/bzip2-c... Thanks to: Alex Crichton and Radically Open Security, and to NLnet Foundation for funding the work through the e-Commons fund with financial support from @minbzk.bsky.social‬ #rustlang #rust

The talks from RustWeek are now available on YouTube! It was great fun and a big honour to get our Rust efforts: youtu.be/2JIFUk4f0iE?...

In part 2 of our air quality monitor project, we’re driving the microbit’s full LED matrix using async Rust: youtu.be/uZDcWA8cCsw

People always ask me “so is AWS using Rust?” Happy to be part of this article shining some light on how Rust is changing the way services are built in AWS.

New project series starts today! In this one we learn a little about I2C & where it fits into embedded Rust: youtu.be/vT4-bvHCbE0

Live from the 10 Years of Rust celebration in Utrecht, Netherlands, we are very happy to announce a new version of Rust, 1.87.0! See the blog post and release notes for all the details! blog.rust-lang.org/2025/05/15/R...

Here are all the posters I designed for RustWeek 2025! 1. "Box<impl Future>" (Back tot the Future) #rustweek #rustweek2025

I am counting the days until @rustnl.bsky.social starts. The tickets have sold out! Looking forward to meet rustaceans, again or for the first time.

Ferrous Systems (I work there!) have agreed to contribute the Ferrocene Language Specification to the Rust Project and allow the Rust Project to take over its development and management rustfoundation.org/media/ferrou...

Even if it's just a number, it feels good to put an official version number on something and have it published. Thanks to my employer, Akiles, for supporting me working on this kind of stuff! embassy.dev/blog/trouble/

No. C++ is not “under attack” (www.theregister.com/2025/03/02/c...). It’s sad, because it reduces the likelihood of (or pushes back) any real progress on the topic.

Today I published arm-targets, a Rust crate that looks at your target string and lets you mark code as only working on specific versions of the Arm architecture. Ideally Rust would have built in target features for this, but it doesn’t. crates.io/crates/arm-targets

It is EXTREMELY cool to me that: * Use of Rust on Embedded platforms is such a high percentage of the ecosystem (16.8% bare metal, 12.9% with an OS) * The usage is increasing year over year Check out the survey results! blog.rust-lang.org/2025/02/13/2...

On my way to FOSDEM for the first time since 2014! I wonder how much it has changed.

I did the podcast thing! It was great fun chatting with Matthias Endler on his “Rust in Production” podcast. We talked about our little Rust based ECU at Volvo Cars and how it came about. Check it out: corrode.dev/podcast/s03e...

Alright, finally my bug hunt retrospective blog has been published! tweedegolf.nl/en/blog/145/... Want a deep technical dive into a really weird error that took ages to find and fix? Then this is for you. #embedded #rustlang

Hey, if you're a Rust and/or embedded person, and you use the probe-rs toolkit (pretty much everyone does in embedded and Rust!), you'd be doing me a huge favor if you took a minute to fill out their survey and/or share internally or with people you know: forms.gle/FRtUwuFCCKgK...

In this one we learn about using embassy to do embedded development with async Rust: youtu.be/pDd5mXBF4tY

Our next event will be a dinner social on January 8th: www.meetup.com/rust-atx/eve...
