# 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 |
|
|
|
- Selectable PWM frequency: 24, 48 and 96 kHz |
|
|
|
- PWM dithering: 10-bit effective throttle resolution |

Compared to BLHeli_S this project only supports the DShot protocol and all analog protocols have been removed to ease code maintenance. |
|
|
|
Bluejay also includes several optimizations. |

## 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`. |

Release files use a naming convention similar to BLHeli: `{T}_{M}_{D}_{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`. |
