The Embedded Working Group Newsletter - 4

This is the fourth bi-weekly newsletter of the Embedded WG where we highlight new progress, celebrate cool projects, thank the community, and advertise projects that need help!

If you want to mention something in the next newsletter, make sure to leave a comment on the issue.

Highlights

• The Embedded WG IRC meetings are now explicitly public, and the agendas for the next meeting can be found in the WG Issues, like this issue for the next meeting
• David shared his utility Form, which takes a single lib.rs (like those created by svd2rust or bindgen), and splits it into structured modules. Check out the nrf52 Chip Support Crate as an example, and try it out for your generated projects!
• astro shared managed, A library that provides a way to logically own objects, whether or not heap allocation is available

Embedded Projects

If you have an embedded project or blog post you would like to have featured in the Embedded WG Newsletter, make sure to mention it on the tracking issue for the next newsletter, we would love to show it off!

• Daniel started work on bluetooth-hci, an abstraction layer for HCI based Bluetooth Controllers, and is using it in his bluenrg crate for STMicro's BlueNRG RF modules
• cr1901 shared his AT2XT project, an adapter that allows use of low cost PS2 keyboards with older computers that expect (now very expensive) XT keyboards. The firmware for this project is based on rtfm, and runs on an msp430 microcontroller. Check out the short blurb by cr1901 summarizing the project
• hannobraun released v0.3 of his lpc82x Chip Support Crate for NXP's LPC82x family of microcontrollers, as well as v0.1 of lpc82x-hal. Check out the lpc82x-hal announcement here!
• japaric released v0.3.1 of heapless which now contains fixed capacity implementations of HashMap and HashSet that work on no_std, do not require an allocator, and use u32 hashes (instead of the default u64).

embedded-hal Ecosystem Crates

As part of the Weekly Driver Initiative, crates that are part of the embedded-hal ecosystem are now tracked in the Awesome Embedded Rust repository. Here is a current snapshot of what is available there:

Help Wanted

• The Embedded WG is looking for contributors for the Rustfest Impl Period. If you will be attending RustFest in Paris, let us know!
• Progress is being made towards Stable Embedded Rust, try out the current preview, and we would love some feedback!
