1. [dcmimu]: An algorithm for fusing low-cost triaxial MEMS gyroscope and accelerometer measurements 
1. [debouncr]: A simple no-std input debouncer to detect rising/falling edges with minimal RAM requirements.

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`.
