This is the 21st newsletter of the [Embedded WG] where we highlight new progress, celebrate cool projects, thank the community, and advertise projects that need help!
-[@eldruin] released a platform-agnostic [driver for the OPT300x][opt300x-driver] family of ambient light sensors and published a [blog post][opt300x-blog-post] with a picture of the device taking lux measurements.

-@mciantyre published a custom runtime and peripheral access crates to support development on the Teensy 4. Check out [the repo][teensy4-rs] to see how it works, discuss the approach, and try it out.

-[@japaric] released version v0.1.0 of [`ufmt`], a smaller (6-40x) and faster (2-9x) alternative to `core::fmt` that's free of dynamic dispatch, recursion (where possible) and panicking branches. `ufmt` is *not* a drop-in replacement for `core::fmt` but it provides `uDebug` and `uDisplay` traits and a family of `uwrite!` macros. In this release the `uwrite!` macros, and the rest of the crate, work on the stable channel.

-[@andre-richter] added two new tutorials for the `Operating System development tutorials in Rust on the Raspberry Pi` series:
- Tutorial 12: [CPU Exceptions: Part 1](https://github.com/rust-embedded/rust-raspi3-OS-tutorials/tree/master/12_cpu_exceptions_part1)

-[@jamesmunns] released two embedded crates:

+
-[`panic-persist`]: A panic handler crate inspired by `panic-ramdump` that logs panic messages to a region of RAM defined by the user, allowing for discovery of panic messages post-mortem using normal program control flow.
50
+
-[`cmim`], or Cortex-M Interrupt Move: A crate for Cortex-M devices to move data to interrupt context, without needing a critical section to access the data within an interrupt, and to remove the need for the "mutex dance"
50
51
-[@tarcieri] released [`aead`] v0.2, providing generic traits for Authenticated Encryption with Associated Data (AEAD) ciphers, which now supports [ergonomic `alloc`-free operation][aead-heapless] via an integration with the [`heapless`] crate. This trait is now implemented by [several crates providing pure Rust implementations of AEAD modes][aead-crates] which may be interesting to embedded users seeking to encrypt/data data in `heapless` buffers, including the [`chacha20poly1305`] and [`aes-siv`] crates (and forthcoming support in the [`aes-ccm`] crate).
