Kevin P. FlemingAchievement unlocked... I've just successfully transmitted the first Protocol Buffers messages over a UART link between an STM32G070 MCU (code written in Rust using Embassy) and a Python test program running on my Debian Linux laptop.Messages are sent with a small header (sync byte and length) and a CRC-16 trailer, and all worked on the second try (on the first try the CRC-16 calculation on the MCU was ignoring the first two bytes of the message - doh!).<a href="https://mastodon.km6g.us/tags/Python" class="mention hashtag" rel="nofollow noopener" target="_blank">#Python</a> <a href="https://mastodon.km6g.us/tags/Rust" class="mention hashtag" rel="nofollow noopener" target="_blank">#Rust</a> <a href="https://mastodon.km6g.us/tags/ProtocolBuffers" class="mention hashtag" rel="nofollow noopener" target="_blank">#ProtocolBuffers</a> <a href="https://mastodon.km6g.us/tags/RustEmbedded" class="mention hashtag" rel="nofollow noopener" target="_blank">#RustEmbedded</a>

Wez Furlong :terminal:weekend tinkering project: hardware wezterm running on a picocalc! This is built using embassy and a slightly tweaked version of the sunset crate for the ssh client. The photo makes things look a lot further along than they really are, because the terminal emulation is virtually non-existent and there is no connection between the keyboard and the ssh session yet. <a href="https://fosstodon.org/tags/embededrust" class="mention hashtag" rel="nofollow noopener" target="_blank">#embededrust</a> <a href="https://fosstodon.org/tags/RustEmbedded" class="mention hashtag" rel="nofollow noopener" target="_blank">#RustEmbedded</a> <a href="https://fosstodon.org/tags/embassyrs" class="mention hashtag" rel="nofollow noopener" target="_blank">#embassyrs</a> <a href="https://fosstodon.org/tags/rustlang" class="mention hashtag" rel="nofollow noopener" target="_blank">#rustlang</a>

Wez Furlong :terminal:has anyone coaxed the <a href="https://fosstodon.org/tags/rp2350" class="mention hashtag" rel="nofollow noopener" target="_blank">#rp2350</a> into using PSRAM with embassy-rs? I couldn't find an obvious example in my searches this morning. I did find some arduino startup code that I can probably translate and adapt, but if someone has already done the heavy lifting, that would save me some effort! <a href="https://fosstodon.org/tags/rust" class="mention hashtag" rel="nofollow noopener" target="_blank">#rust</a> <a href="https://fosstodon.org/tags/embeddedrust" class="mention hashtag" rel="nofollow noopener" target="_blank">#embeddedrust</a> <a href="https://fosstodon.org/tags/rustembedded" class="mention hashtag" rel="nofollow noopener" target="_blank">#rustembedded</a> <a href="https://fosstodon.org/tags/pico2" class="mention hashtag" rel="nofollow noopener" target="_blank">#pico2</a>

James LoganThis week, I added N-dimensional cubic spline support to InterpN (<a href="https://hachyderm.io/tags/RustLang" class="mention hashtag" rel="nofollow noopener" target="_blank">#RustLang</a> library and <a href="https://hachyderm.io/tags/Python" class="mention hashtag" rel="nofollow noopener" target="_blank">#Python</a> bindings). This approach is similar to a De Casteljau recursion in higher dimensions, but uses a depth-first traversal of the calculation to avoid actualizing 4^(ndim-1) values simultaneously, instead keeping memory usage to a linear O(ndims) and entirely on the stack. As a result, it requires no heap allocation at all, doesn't even use the standard library, and is <a href="https://hachyderm.io/tags/RustEmbedded" class="mention hashtag" rel="nofollow noopener" target="_blank">#RustEmbedded</a> -compatible.

DaniloAfter roughly 6 years of work, embedded-hal 1.0 is finally stabilized and released!- <a href="http://blog.rust-embedded.org/embedded-hal-v1/" rel="nofollow noopener" translate="no" target="_blank">http://blog.rust-embedded.org/embedded-hal-v1/</a> - <a href="https://github.com/rust-embedded/embedded-hal/issues/177" rel="nofollow noopener" translate="no" target="_blank">https://github.com/rust-embedded/embedded-hal/issues/177</a>embedded-hal (often abbreviated e-h) is a hardware abstraction layer in the form of a collection of Rust traits (both sync and async). It allows writing device drivers that will run on any hardware that implements the HAL.Stabilization is a great thing for the Embedded Rust ecosystem.

Joel MichaelHey makers, hackers, and electronics folks of the fediverse, what’s your go-to small cheap dev board that ISN’T an ATmega (too small) or ESP32 (too cursed)?

Joel MichaelHoly shit Rust debug builds are GIGANTIC! At first i thought it was oh this is just what Rust does I guess, but no, things go back to normal when the compiler optimisation option is changed from 0. This poor embedded binary grows 4x in size going from -Oz to -O0 before debug symbols are added, and stack usage explodes by a similar amount. <a href="https://aus.social/tags/Rust" class="mention hashtag" rel="nofollow noopener" target="_blank">#Rust</a> <a href="https://aus.social/tags/RustLang" class="mention hashtag" rel="nofollow noopener" target="_blank">#RustLang</a> <a href="https://aus.social/tags/RustEmbedded" class="mention hashtag" rel="nofollow noopener" target="_blank">#RustEmbedded</a>

James LoganHey, folks - last week, I published the first version of `strobe`, a library for elementwise array expressions.It is no-std and no-alloc compatible.For large source arrays in nontrivial expressions, it is also about 2-3x faster than the usual method for ergonomic array operations (allocating storage for each intermediate result).Docs: <a href="https://docs.rs/strobe/0.1.3/strobe/index.html" rel="nofollow noopener" translate="no" target="_blank">https://docs.rs/strobe/0.1.3/strobe/index.html</a>Github: <a href="https://github.com/jlogan03/strobe" rel="nofollow noopener" translate="no" target="_blank">https://github.com/jlogan03/strobe</a>Full benchmark outputs: <a href="https://github.com/jlogan03/strobe/pull/6" rel="nofollow noopener" translate="no" target="_blank">https://github.com/jlogan03/strobe/pull/6</a><a href="https://hachyderm.io/tags/rustlang" class="mention hashtag" rel="nofollow noopener" target="_blank">#rustlang</a> <a href="https://hachyderm.io/tags/rustembedded" class="mention hashtag" rel="nofollow noopener" target="_blank">#rustembedded</a>
