This is another stupid STM32 "+" copter firmware written with ST HAL Driver.

1. Do NOT trust this firmware.
2. HAL Driver files are ignored. Regenerate with STM32CubeMX to get the Driver.
3. This project is written with Keil5. Do open MDK-ARM/BFlight.uvprojx.
4. Documents can be found in Docs folder or somewhere else.
