Trouble connecting FrSky XM+ receiver to ESP32 #55

The XM+ operates with inverted Serial logic and this library should be capable of that but how to I enable it? Is inverted mode automatically detected? Also I'm having a hard time finding what the logic levels of the XM+ are. I hope they are 3.3v otherwise I've blown out that GPIO. If anyone knows let me know please.

Thanks !
