RC input is configured on the R1 (UART1_RX) pin. It supports all serial RC
protocols. For protocols requiring half-duplex serial to transmit
telemetry (such as FPort) you should setup SERIAL2 as an RC input serial port,
telemetry (such as FPort) you should setup SERIAL1
with half-duplex, pin-swap and inversion enabled.

## FrSky Telemetry

FrSky Telemetry is supported using the T2 pin (UART2 transmit). You need to set the following parameters to enable support for FrSky S.PORT

- SERIAL2_PROTOCOL 10
- SERIAL2_OPTIONS 7
- SERIAL2_OPTIONS 15
