Setting up Heltec Wireless Stick Lite v3 for Meshtastic

I picked up the Heltec Wireless Stick Lite v3 as it was the cheapest Meshtastic hardware I could find. The documentation was rather lacking and outdated, so after figuring it all out I decided to write it up here.

General Resources

• Official Heltec WSLv3 docs
• Product page (the URL says v2, but the page says v3)
• Meshtastic Guide

  // function BoolToStr(B: Boolean; UseBoolStrs: Boolean = False): string;
  Writeln('BoolToStr(??, True)');                 //  BoolToStr(??, True)
  WriteLn('True = ' + BoolToStr(True, True));     //  True = True
  WriteLn('False = ' + BoolToStr(False, True));   //  False = False
  Writeln('BoolToStr(??, False)');                //  BoolToStr(??, False)
  WriteLn('True = ' + BoolToStr(True, False));    //  True = -1
  WriteLn('False = ' + BoolToStr(False, False));  //  False = 0

  // class function ToString(const Value: Boolean; UseBoolStrs:
  //   TUseBoolStrs = TUseBoolStrs.False): string;
