Hello, according to the ardupilot documentation The Spektrum SRXL protocol is supported through a direct UART connection:
I understand the default Navio RCIN only accepts PPM (which Spektrum stopped supporting) … but my questions is: is there a way to directly connect to an available raspberry PI serial port and use it for the RCIN function?
This link indicates a potentially spare UART on IO17 / IO18 …
… but I frankly have no idea how that would map to a serial port recognizable by ardupilot / mission planner. I guess in general I’m a little fuzzy on mappings from the NAVIO board to the arduino to ardupilot to mission planner.
