/****************************************************************************************************************************
  RP2040_WiFi.ino
  For RP2040 boards using WIFI_GENERIC modules/shields, using much less code to support boards with smaller memory
  
  WiFiManager_Generic_WM_Lite is a library for the Mega, Teensy, SAM DUE, SAMD and STM32 boards 
  (https://github.com/khoih-prog/WiFiManager_Generic_Lite) to enable store Credentials in EEPROM/LittleFS for easy 
  configuration/reconfiguration and autoconnect/autoreconnect of WiFi and other services without Hardcoding.
