Remote blinky on nRF52 using Rust
summary
Builds a remote blinky on nRF52 with Rust using the radio at 2.4 GHz (IEEE 802.15.4 style) to send tiny commands between two boards; sets up two devices each with a button and LED, debounces at ~10 ms, blinks for 1 second, and uses one of 16 radio channels. Uses the community nrf-hal crate, configures the external oscillator so the radio works, and contributes a non-blocking receive PR to handle concurrent button and radio events; the live demo works.
