Using the latest version of the IRremote library

Other Hardware Home Automation
1

I have the latest version of the IRremote library installed. I am using a SAMSUNG remote. I cannot use this function receiver.decode(&results). I have to use receiver.decode(). For the "1" button on my SAMSUNG remote, the hex value is E0E020DF. Which command do I use to tell if the received IR is that value?

What data type is the E0E020DF ?

Is it an integer, an array of chars or a String ?

Please post a sketch that illustrates reading the value

Try IrReceiver.decodedIRData.address (0xE0E0) and IrReceiver.decodedIRData.command (0x20DF)

Sample:

void loop() {
  if (IrReceiver.decode() && IrReceiver.decodedIRData.protocol == SAMSUNG) {
      Serial.print((char)IrReceiver.decodedIRData.command);
    IrReceiver.resume();
  }
}

I tried this:

#include <IRremote.h>

int irrecv_pin = A0;
IRrecv receiver(irrecv_pin);

void setup() {
Serial.begin(9600);
receiver.enableIRIn();
}

void loop() {
if (receiver.decode() && receiver.decodedIRData.protocol == SAMSUNG) {
Serial.println(receiver.decodedIRData.command);
receiver.resume();
}
}

Things were going fine until it stopped receiving IR signal. All the wirings are done correctly. The remote has enough battery power as tested from the multimeter. When I press any buttons on the remote, it does not receive any signal.

Here you can see a running example: sketch.ino - Wokwi Arduino and ESP32 Simulator

With the Wokwi simulation only the NEC protocol works.
Replace in your program NEC by SAMSUNG. Then it should also work with a Samsung remote control.

I have used the digital pin 2 for the example. No analog pin.

I tried it and it works fine. Thank you for the help.

Great. Then it would be nice if you mark the thread as solved.
