IRremote Libary Version 4.0 to 2.0

[djxom]

Hi Guys,

Today I tried to read and send signals via an infrared receiver and transmitter. Everything went well except for sending. Then there was this message:

Thank you for using the IRremote library!

It seems, that you are using a old version 2.0 code / example.

This version is no longer supported!

Please use one of the new code examples from the library,

available at "File > Examples > Examples from Custom Libraries / IRremote".

Start with the SimpleReceiver or SimpleSender example.

The examples are documented here:

GitHub - Arduino-IRremote/Arduino-IRremote: Infrared remote library for Arduino: send and receive infrared signals with multiple protocols

A guide how to convert your 2.0 program is here:

GitHub - Arduino-IRremote/Arduino-IRremote: Infrared remote library for Arduino: send and receive infrared signals with multiple protocols

Thanks

The code is from this Video: https://www.youtube.com/watch?v=bketb8PZtuQ&t=208s

Now I understand almost 0 of the code examples and I can't find anything about it on GitHub. Many thanks for your trouble.

Welcome to the forum

There are changes to the functions between version 2 and version 4 of the IRremote library

If the code that you are using was written for version 2 then there is a chance that it will not work with version 4 of the library and vice versa

Which version of the IDE and which version of the IRremote library do you have installed ?

Have you tried the examples that come with the library ?

Ok I found a solution thanks

I have downgrade the Version. I dont need the new version. I didn't know it was possible, but now it works. It´s ok for me

It would be nice to get the 4.0 version, given the 2.0 below:

#include "IRremote.h"
#define receiverPin 2

IRrecv irrecv(receiverPin); //create instance of 'irrecv'
decode_results results;     //create instand of 'decode_results'

void setup(){
  Serial.begin(9600);
  irrecv.enableIRIn();      //Start the receiver
}

void loop(){
  if(irrecv.decode(&results)){
    Serial.println(results.value, HEX);
    irrecv.resume();  //receive the next value
  }
  delay(100); 
}
