1. [num-format](https://crates.io/crates/num-format): Crate for producing string representations of numbers, formatted according to international standards, e.g. "1,000,000" for US English - 
1. [`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. - 
1. [pc-keyboard]: A PS/2 keyboard protocol driver. Transport (bit-banging or SPI) agnostic, but can convert Set 2 Scancodes into Unicode. 
1. [qei](https://crates.io/crates/qei) : A qei wrapper that allows you to extend your qei timers from a 16 bit integer to a 64 bit integer. - 
1. [qemu-exit]: Quit a running QEMU session with user-defined exit code. Useful for unit or integration tests using QEMU. - 
1. [register-rs](https://github.com/rust-embedded/register-rs): Unified interface for MMIO and CPU registers. Provides type-safe bitfield manipulation. `register-rs` is Tock registers with added support for CPU register definitions using the same API as for the MMIO registers. This enables homogeneous interfaces to registers of all kinds. - 
1. [scroll](https://crates.io/crates/scroll): extensible and endian-aware Read/Write traits for generic containers - 
1. [smoltcp](https://github.com/m-labs/smoltcp): a small TCP/IP stack that runs without `alloc`. 
1. [tinybmp](https://crates.io/crates/tinybmp): No-std, no-alloc BMP parser for embedded systems. [Introductory blog post](https://wapl.es/rust/2019/03/04/embedded-graphics-0.4.7-bmp-support.html) - 
1. [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. 
1. [wyhash]: A fast, simple and portable hashing algorithm and random number generator. -
