# PicoCalc OS (Rust) # PicoCalc OS (Rust)
A simple operating system for the **Clockwork PicoCalc**, written in Rust. A simple kernel and applications for the **Clockwork PicoCalc**, written in Rust.
This project provides a minimal kernel, ABI, and user-space applications to experiment with OS development on constrained hardware. This project provides a minimal kernel, ABI, and user-space applications to experiment with OS development on constrained hardware.
## Status ## Status
Basic synchronous applications are working great. Basic synchronous applications are working great.
Current focus is on exanding applications and porting software, finding bufs in ffi, and making sure the kernel is as stable as possible. Current focus is on exanding applications and porting software, finding bugs in ffi, and making sure the kernel is as stable as possible.
