: To control the aircraft, the board interfaces with standard RC receivers using the FlySky iBus serial protocol . Developers write custom interrupt-driven Universal Asynchronous Receiver-Transmitter (UART) routines to read incoming byte streams, decode channel positions, and run checksum verifications. Mh-fc V2.2
For pilots building FPV (First-Person View) quadcopters, Betaflight is the industry standard. The MH-FC V2.2 targets can be flashed via a standard USB-C or Micro-USB interface. Betaflight allows users to configure motor mapping, set up receiver channels, and adjust PID/Feedforward loops for aggressive freestyle or racing maneuvers. INAV for Navigation The MH-FC V2
You are running a legacy V1.x system with highly customized, unmaintained drivers. In that case, plan a staged migration over 3–6 months. Also, if your hardware is non-compatible (check the HCL for V2.2-specific chip revisions), stay on V2.1. In that case, plan a staged migration over 3–6 months
To help clarify your implementation of this board, please tell me:
An IMU (like the MPU6050) for tilt and motion sensing and often a GNSS module for position data. Power System:
V2.2 introduces stricter bit-timing requirements. Solution: Recalculate the Nominal Bit Time (NBT) and Data Bit Time (DBT). Use the new can:autobaud command to let V2.2 negotiate the correct timing.
