## Community

In 2018 Rust community has created an embedded workgroup to help drive adoption in the Rust ecosystem.

- [Embedded WG](https://github.com/rust-lang-nursery/embedded-wg/), including newsletters with progress updates.

- You can usually find the members of the embedded WG on the `#rust-embedded` channel (server: `irc.mozilla.org`).

- [embedded.rs](https://t.me/embedded_rs) Telegram chat about Rust for microcontrollers in Russian language.

- [heapless](https://crates.io/crates/heapless): provides `Vec`, `String`, `LinearMap`, `RingBuffer` backed by fixed-size buffers  - ![crates.io](https://img.shields.io/crates/v/heapless.svg)
- [intrusive-collections](https://crates.io/crates/intrusive-collections): intrusive (non-allocating) singly/doubly linked lists and red-black trees - ![crates.io](https://img.shields.io/crates/v/intrusive-collections.svg)
- [managed](https://crates.io/crates/managed): provides `ManagedSlice`, `ManagedMap` backed by either their std counterparts or fixed-size buffers for `#![no_std]`. - ![crates.io](https://img.shields.io/crates/v/managed.svg)
- [nalgebra](https://crates.io/crates/nalgebra): general-purpose and low-dimensional linear algebra library - ![crates.io](https://img.shields.io/crates/v/nalgebra.svg)
- [smoltcp](https://github.com/m-labs/smoltcp): a small TCP/IP stack that runs without `alloc`
- [embedded-graphics](https://crates.io/crates/embedded-graphics): 2D drawing library for any size display - ![crates.io](https://img.shields.io/crates/v/embedded-graphics.svg)

- [vga-framebuffer]: A VGA signal generator and font renderer for VGA-less microcontrollers. Used by [Monotron](https://github.com/thejpster/monotron) to generate 48 by 36 character display using 3 SPI peripherals and a timer.
- [menu]: A basic command-line interface library. Has nested menus and basic help functionality.
- [pc-keyboard]: A PS/2 keyboard protocol driver. Transport (bit-banging or SPI) agnostic, but can convert Set 2 Scancodes into Unicode.
