This variant can be used with Flysky RC Receivers compatible with IBUS protocol.<br />
It will send all channels on a single wire like PPM, but is more reliable as it is a digital protocol using a USART frame and checksum.<br />
Default number of channels for IBUS in config.h is 14.
Default number of channels for IBUS in config.h is 14 (successfully tested with Flysky fs-I6AB and RX2A).
## Wiring:
* Connect green wire to IBUS port of your receiver on right sensor cable(shorter)
* If you want to use the left cable instead, replace CONTROL_SERIAL_USART3 by CONTROL_SERIAL_USART2 and FEEDBACK_SERIAL_USART3 by FEEDBACK_SERIAL_USART2 in config.h
⚠ Red wire from sensor cable delivers 15v !!!
Use 3.3v from programming port, 5v from hall sensor cable, or a voltage regulator.

If the board is beeping
* Check the number of channels, even if you transmitter only handles 6 channels, you receiver might transmit more channels
* Make sure you enabled PPM on your transmitter
* Make sure you enabled IBUS on your transmitter, on some models it is activated together with PPM
* Make sure you are using the sensor cable(left or right) selected in config.h
* On some boards the wire colors might differ, try the blue wire
