+# The Embedded Working Group Newsletter - 4
+
+> 2018-04-28
+
+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`], a crate for fixed capacity implementations of `HashMap` and `HashSet` that does not require the use of `std`, an allocator, and used `u32` hashes (instead of the default `u64`).
