Usage

Download the Library and extract the folder in the libraries of Arduino IDE, see example for rasperry pi pico

Include DWIN Library (eg. DWIN_Arduino.h)

#include <DWIN_Arduino.h>
#define DGUS_BAUD 115200

//#define FORCEHWSERIAL
//using Boards with Hardware serial you may need extra
// defines in here and DWIN_Arduino.h eg. Teensyduino, nano (only 1 serial port) etc
// or #define FORCEHWSERIAL here and in DWIN_Arduino.h
#if defined(__AVR_ATmega1280__) || defined(__AVR_ATmega2560__) || defined(FORCEHWSERIAL)
  #define DGUS_SERIAL Serial2
  DWIN hmi(DGUS_SERIAL, DGUS_BAUD);

// If Using ESP 32
#elif defined(ESP32)
#define DGUS_SERIAL Serial2
DWIN hmi(DGUS_SERIAL, 16, 17, DGUS_BAUD);

// If Using Arduino Uno
#else
DWIN hmi(2, 3, DGUS_BAUD);
#endif

Define callback Function

// Event Occurs when response comes from HMI
void onHMIEvent(String address, int lastByte, String message, String response){  
  Serial.println("OnEvent : [ A : " + address + " | D : "+ String(lastByte, HEX)+ " | M : "+message+" | R : "+response+ " ]"); 
  if (address == "1002"){
  // Take your custom action call
  }
}

In void setup()

  hmi.echoEnabled(false);      // To get Response command from HMI
  hmi.hmiCallBack(onHMIEvent); // set callback Function

In loop()

  // Listen HMI Events
  hmi.listen();

Brightness Control

  // Turn off Backlight
  hmi.setBrightness(0);

  // Turn on Backlight
  hmi.setBrightness(100);

  // Get Backlight level
  int brightness = hmi.getBrightness();
