Rust Meets Zephyr: Building Safer Embedded Applications
summary
Rust on Zephyr is shown as a workable workflow: cargo-driven builds integrated via Zephyr’s west toolchain, bindgen-generated C bindings, and a live micro:bit countdown that boots, flashes, and runs. Practical issues include C interop requiring unsafe fences, a fragile 16‑byte stack buffer for string conversion that can panic at runtime, and the no_std limitation blocking standard library features. The demo compiles with west build, flashes with west flash, and the app runs but needs safer abstraction layers and more drivers.
