We're going to Nuremberg! You can find us at #EmbeddedWorld in Hall 4 at booth 4-402. Come say hi!

Bare-metal SMP Armv8-R AArch32 in Rust, ping ponging Software Generated Interrupts between cores using the Generic Interrupt Controller v3. I'm very happy to see this working. github.com/thejpster/aa...

Hell yeah, Cortex-R (ARMv7-R) support in probe-rs :D github.com/probe-rs/pro...

After poking the PL192 VIC registers in our Cortex-R5F for a few hours and wondering why nothing is happening (and no hardfaults 🤔), remember to double check that the vendor has not replaced the standard interrupt controller with their own 💔 Assumptions is the mother of all ... VIM != VIC

Rust 1.93.0 has been released! 🌈 🦀✨ This release includes a new musl version for the *-linux-musl targets, adds support for #​[cfg] inside asm!(), and adds [T]::as_array, VecDeque::{pop_front_if, pop_back_if}, Vec/String::into_raw_parts, fmt::form_fn, and more! ✨ blog.rust-lang.org/2026/01/22/R...

It's been 0 days since I had to convince someone that CRC is not equivalent to encryption.

Linkers for embedded kinda suck, no? Do you work at a big company who could use a new one? At @tweedegolf.bsky.social we have some amazing people who could build an awesome new embedded linker. We should talk.

Maybe a stupid question, but why is schematics for PCB design not code? For more advanced "PCBs" (read ICs) we use HDL and in the end if there is an MCU we code it. If it was "code" I'm wondering what amazing linters, CI, checks, integrated knowledge about parts, type safe modules ... could be done.

Typst 0.14 is out now! Get ready for production with accessibility, PDFs as images, character-level justification, and more. Learn about more of the highlights in Typst 0.14 in the thread below ⤵️

Ah yes, the radio test box that finds 99% of logic errors 😁 The kind of automated testing that can be done is an absolute treasure. Yankiness is included.

I'm excited to share what I've been working on with @erikjee.bsky.social: RustNL's #rustlang Maintainers Fund! Many people and companies contributing to Rust, but there are fewer and fewer paid positions for general maintenance (reviews,cleanups,etc). We need to fix that. bsky.app/profile/rust...

We need your help to get Typst 0.14 over the finish line: The release candidate with accessible PDFs, character-level justification (not even in LaTeX!), and more landed today! Check your documents, packages and against "Typst 0.14.0 Testing" on the web or the new compiler.

Them: But no-one is using Rust in Production Me: Well, actually… ferrous-systems.com/blog/rust-wh...

Cool! Happy with the playground result. Love how instant compilation is :D I've probably committed crimes against the web with my HTML/CSS skills, but it works :) diondokter.github.io/device-drive... The home page is super mega WIP, but that wait can until other more important stuff is done.

Rust 1.90.0 has been released! ✨🦀 This release makes LLD the default linker on x86-64 linux-gnu and adds `cargo publish --workspace` to publish an entire workspace all at once! Check out the blog post and release notes for more: blog.rust-lang.org/2025/09/18/R...

So, how yanky are your test setups at work sometimes? I'll start 😅

New heapless version is out! blog.rust-embedded.org/heapless-091 (And it's looking juicy)

We're launching the embedded-cal project: Providing access to hardware accelerated and formally proven cryptographic algorithms on #embedded systems in #rustlang. For this, I'm teaming up with @inria Paris and @cryspen, supported by the #eu funded @NGIZero. Right now we're going through […]

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...

I feel like there would be a HUGE amount of ecosystem value for Rust and async/await, if there was funding and the right dev(s) available to focus on improving: * Memory usage + copies of futures/async fns: particularly wrt overlapping data across yield * Improving codegen size/perf * opt-footguns

I'm giving a talk at Oxidize conference 2025, hope to meet you all there 🚀🎉

University took it's toll. Korken = bottle cap ... 😅

I remember reading long ago that COBS framing with CRCs as part of the data could greatly reduce the effectiveness of the CRC checksum and that care beds to be taken, but I'm unable to find where I read this. Does anyone know where this comes from, or if I'm mistaken?

🦀 Hello World! The Rust project now has an official presence on Bluesky! ✨ We'll be posting the same on our Mastodon and Bluesky accounts, so you won't miss anything on either platform.

MISRA have produced a document outlining how MISRA C rules apply to both safe and unsafe Rust. It’s like someone designed a language to fix a bunch of obvious pain points. misra.org.uk/app/uploads/...

People: The #rustlang std is way too small! Me, an embedded developer used to #![no_std]:

Did you hear the news? Builds happening now... gitlab.com/kicad/code/k...

OK, it's official on the website now: KiCad 9 is out! www.kicad.org/blog/2025/02...

Bluesky has grown a bit since I last shared some of my favorite lists and feeds here, so I thought it was time for a quick 🧵 so everyone new can find them as well! I’m mostly interested in embedded dev with Rust, but a lot of these goes across the entire maker space, hobbiest or professionals!

Now starts the journey to FOSDEM 🚀

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

Currently in Berlin, meeting with Ferrocene - it's going to be really interesting 🚀 I've not been in Berlin since the first Oxidize conference, time really goes fast. I quite enjoy it 😁

"By forcing me to get object ownership in order and separate concerns, the borrow checker prevented a logic bug." #rustlang mental-reverb.com/blog.php?id=46

I've booked my trip to FOSDEM25, hope to see you all there! 🚀

Here I started with learning openEMS to simulate an antenna, and now I'm writing a KiCAD plugin to setup the simulation directly there 😅 Why is a project never small?

Started my openEMS journey yesterday too see if I can I use it for antenna simulation instead of Ansys HFSS. From what I've seen on Twitter it should be doable. Started with a patch antenna that was quite easy. Now to try an IFA, with the final aim for a dual-band (868 MHz, 2.4 GHz) antenna.

Next project! A signal recorder for our radio tracing test bench. Made to analyze 32 radios in our product in parallel.

Oh, hey, the repost of my sequential-storage blog is now on the Memfault interrupt blog! Thanks for sharing James!

Time for work to start on a new project :D

Amaranth 0.5.0 has been released! Read the [changelog] to see what's new (a lot! we've accepted and implemented nineteen RFCs) or jump directly into the [playground] [changelog]: amaranth-lang.org/docs/amarant... [playground]: amaranth-lang.org/play/

I’ve published `bsky-sdk`, a Rust library specialized for using Bluesky. It has moderation and rich text functionalities that are almost equivalent to the official TypeScript SDK! #bluesky #atproto #rust #atrium-rs Please refer to the crates.io page for detailed usage. crates.io/crates/bsky-...

One week into "how hard can it be to implement DTLS 1.3" and I must say, the RFCs are awesome! The answer is though not very hard, just a lot of details to track :) Each step is nicely documented. Side note, it's only the PSK part I'm implementing with ECDHE.

Overheard at the water-cooler: "... It is clear that C/C++ is the asbestos of software, and that a sanitation is needed." 😅

route route route route. Pretty happy with my two-RP2040 plus accessories PCB, this is the second draft of routing, and using the "one layer North/South, one layer East/West" trick made it much more manageable despite a lot of connections.
