# Bluejay Digital ESC firmware for controlling brushless motors in multirotors. A fork of [BLHeli_S](https://github.com/bitdump/BLHeli) based on revision 16.7. ## Summary Bluejay aims to be an open source successor to BLHeli_S bringing DShot RPM telemetry to ESCs with Busy Bee MCUs. Compared to BLHeli_S this project only supports the DShot protocol and all analog protocols have been removed to ease code maintenance. A more detailed list of changes can be seen in the project [changelog](CHANGELOG.md). ## Project State Bluejay is still in early development and further testing is needed before it can be used for real flight. **Current Features:** - Digital signal protocol: DShot 300 and 600 - Bidirectional DShot: RPM telemetry - Selectable PWM frequency: 24 and 48 kHz ## Flashing ESCs The Bluejay firmware can be flashed to BLHeli_S compatible ESCs using BLHeli Configurator. All releases can be found in the [releases](https://github.com/mathiasvr/Bluejay/releases) section. Files currently use similar naming convention to BLHeli: `{T}_{M}_{DT}_{P}_{V}.hex`. - T: Target layout (`A` - `W`) - M: MCU type, `L` for BB1 (24MHz), `H` for BB2 (48MHz) - DT: Deadtime (aka Feton_Delay) - P: PWM frequency `24` or `48` - V: Bluejay version eg. `0.3.0`.
