/*
   RadioLib Non-Arduino ESP-IDF Example

   This example shows how to use RadioLib without Arduino.
   In this case, a Liligo T-BEAM (ESP32 and SX1276)
   is used.

   Can be used as a starting point to port RadioLib to any platform!
   See this API reference page for details on the RadioLib hardware abstraction
   https://jgromes.github.io/RadioLib/class_hal.html

   For full API reference, see the GitHub Pages

// DIO0 pin:  26
// NRST pin:  14
// DIO1 pin:  33

// it must be declared as "extern C" because the compiler assumes this will be a C function
