Usage

Download the Library and extract the folder in the libraries of Arduino IDE

Include DWIN Library (eg. DWIN.h)

#include <DWIN.h>

Initialize the hmi Object with Rx | Tx Pins and Baud rate

// If Using ESP32 Or Arduino Mega 
#if defined(ESP32)
  #define DGUS_SERIAL Serial2
  DWIN hmi(DGUS_SERIAL, 16, 17, DGUS_BAUD); // 16 Rx Pin | 17 Tx Pin
// If Using Arduino Uno
#else
  DWIN hmi(2, 3, DGUS_BAUD);    // 2 Rx Pin | 3 Tx Pin
#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();
