/*
   RadioLib Morse Transmit Example

   This example sends Morse code message using
   SX1278's FSK modem.

   Other modules that can be used for Morse Code:
    - SX127x/RFM9x
    - RF69
    - SX1231
    - CC1101
    - SX126x
    - nRF24
    - Si443x/RFM2x
    - SX128x

   For default module settings, see the wiki page
   https://github.com/jgromes/RadioLib/wiki/Default-configuration

   For full API reference, see the GitHub Pages
