 * This is DWIN HMI Library for Arduino Compatible Boards. More Info about Display Visit
 * Official Site --> https://www.dwin-global.com/
 * 
 * Example sketch/program showing how to initialize DWIN Hmi with Arduino Or ESP32 Boards
 * In this example we can see on setup loop we change the page no and set the brightness &
 * Listen to display Events from serial port
 * 
 * DWIN HMI to Various Boards Pinout Connection
