I was trying to interface a fysky D4R-II with a Parrot Disco today, and had little luck.
With a stock firmware build and the frsky plugged into the Disco, I see a SBUS input message from the ArduPilot Linux HAL in the Disco’s logs. So, I’m pretty sure this is an Ardupilot question.
Is there a parameter setting (or a build option) for switching back and forth between different types of inputs? If so, where should I look for more information?
