ESP32: candidate expects 4 arguments, 5 provided when compile

#include "sbus.h"

Looks like that particular ESP32 core dev team didn't include the ability to handle inverted serial. Are you stuck with that ESP32 core library?

The updated example code in #80 should help show what's required for setting up the example on ESP32. That seemed to compile / run ok locally for me (using v3.0.7 by Espressif Systems for the board manager). Although it looks like you're already adjusted the constructor call to add the required args for sbus_tx setup, so it may be a different issue....
