   RadioLib Non-Arduino Raspberry Pi Example

   This example shows how to use RadioLib without Arduino.
   In this case, a Raspberry Pi with WaveShare SX1302 LoRaWAN Hat
   using the lgpio library
   https://abyz.me.uk/lg/lgpio.html

   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

// include the library
#include <RadioLib.h>

// include the hardware abstraction layer
#include "hal/RPi/PiHal.h"

// create a new instance of the HAL class
// use SPI channel 1, because on Waveshare LoRaWAN Hat,
// the SX1261 CS is connected to CE1
PiHal* hal = new PiHal(1);

// now we can create the radio module
// pinout corresponds to the Waveshare LoRaWAN Hat
// NSS pin:   7
// DIO1 pin:  17
// NRST pin:  22
// BUSY pin:  not connected
SX1261 radio = new Module(hal, 7, 17, 22, RADIOLIB_NC);

// the entry point for the program
int main(int argc, char** argv) {
  // initialize just like with Arduino
  printf("[SX1261] Initializing ... ");
  int state = radio.begin();
  if (state != RADIOLIB_ERR_NONE) {
    printf("failed, code %d\n", state);
    return(1);
  }
  printf("success!\n");

  // loop forever
  int count = 0;
  for(;;) {
    // send a packet
    printf("[SX1261] Transmitting packet ... ");
    char str[64];
    sprintf(str, "Hello World! #%d", count++);
    state = radio.transmit(str);
    if(state == RADIOLIB_ERR_NONE) {
      // the packet was successfully transmitted
      printf("success!\n");

      // wait for a second before transmitting again
      hal->delay(1000);
