Arduino library for the Flysky/Turnigy RC iBUS protocol - servo (receive) and sensors/telemetry (send) using hardware UART (AVR, ESP32 and STM32 architectures)
With this library you can interface to any RC receiver that supports the Flysky iBUS protocol (such as TGY-IA6B). Flysky iBUS uses a half-duplex asynchronous protocol format at 115200 baud. The library requires at least one free hardware UART (serial) port. The library can be used to receive data (typically servo data) and send data (telemetry or sensors).

This library is compatible with the avr, esp32, stm32, mbed architectures so you should be able to use it on the following Arduino boards:

Compatibility Note

Note: while the library is supposed to compile correctly on these architectures, it might require specific hardware features that may be available only on some boards.


To use this library, open the Library Manager in the Arduino IDE and install it from there.
