How to fix Arduino IRremote Error: Use of decode(decode_results *aResults) is deprecated! Use decode() instead!

sketch with "Use of decode(decode_results *aResults) is deprecated! Use decode() instead!" error warning:
int input_pin = 5;
IRrecv IRR (input_pin);
decode_results results;

void setup () {
IRR.enableIRIn ();
}

void loop () {
if (IRR.decode (&results)) {
IRR.resume ();
}
}

without warning:
int input_pin = 5;
IRrecv IRR (input_pin);

void setup () {
IRR.enableIRIn ();
}

void loop () {
if (IRR.decode ()) {
IRR.resume ();
}
}

how to fix 0 (zero) result:
reinstall/restore/revert IRremote library to version 2.8.0

[masterkit]

Fantastic!!! only 2.8.0 library work correctly, and you fix very super! thank you fantastic video!!! Very help for me!

[taher]

Thank you. This saved me a lot of time

The function decode(&results)) is deprecated and may not work as expected! Just use decode() - without any parameter.

[aquilanera]

That's the solution, thank you !

[RedScythe]

thank you so much. i appreciated it cuz it worked

[yugmathakore]

Hey, I am also getting the error of 0 in the result for any button I press inspite of adding 2.8.0 version of ir remote.
I am attaching the sketch below. Please help me figure out the error

#include <IRremote.h>

#include <IRremote.h>

#define IRPIN 7

IRrecv irrecv(IRPIN);
decode_results result;

void setup()
{
Serial.begin(9600);
irrecv.enableIRIn();
Serial.println("Enabled IRin");
}

void loop(){
if (irrecv.decode())
{

irrecv.resume();
}
}

doesn't work for me. serial monitor show only 0 if i push a button

[nikodemkarcz]

What should i do in switch() except results.value???
Please I need your help

[manueledeambrosi]

Hi, I'm trying to decode the keys of a remote control; I followed your video and solved this problem ... but I don't understand why in the serial monitor it gives me only zeros and not the code of each key. Could you help me? Thank you, I await your reply :-)

Bro knp ya setiap tombol saya pencet angka selalu berubah..misalkan angka 1 saya pencet di serial monitor tidak selalu sama..

#include <AFMotor.h>
#include <IRremote.h>

IRrecv IR(A2);

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

void loop() {
if (IR.decode()) {

IR.resume();
}
delay (100);
if (IR.results.value == UP) {
forward();

back();

Tolong bantu saya bro..

[austindilip]

Sir I typed the program as given in the description box. But I got an error saying that IRrecv does not name a type. Can you help me out

[ahgrigor]

the serial port just displays 0's whenever I click the remote instead of the hex value

[ssyal]

Hi,
I followed the steps you showed but for some reason, I always get 0 when I press any button on the remote. Kindly help.
this is the code that I used:

#include <IRremote.h>

// Define sensor pin
const int RECV_PIN = 4;

// Define IR Receiver and Results Objects
IRrecv irrecv(RECV_PIN);
decode_results results;


void setup(){
// Serial Monitor @ 9600 baud
Serial.begin(9600);
// Enable the IR Receiver
irrecv.enableIRIn();
}

void loop(){
if (irrecv.decode()){
// Print Code in HEX
Serial.println(results.value, HEX);
irrecv.resume();
}
}

I have a problem when I press any bottons it gives me a zero I use ir 1838 with arduino mega

[jimba]

Thank you. It finally worked after months.
Does anyone know why my serial prints the result twice.
I copy and pasted the code. At first it printed 5 times. I added a 500 delay at the end, now it prints twice.
Adding a larger delay doesn't reduce it to one time.

[giannissotiropoulos]

hello, thank you so much for your help i was struggling for days..but i do have another problem when i press for example on-off button i get two different results 4C and 84C and also in every different button i tried i am getting two different results something and something with the 8 as the first digit..I am always getting two results for every button and one of them is with the 8 as a first digit..any ideas?
thank you in advance

[victormgt]

Thanks you, but, I only received five zeros, Do you have any idea about that?

[masterkit]

Для русских, работает только версия 2.8.0, остальные версии кривые и глючные до ужаса, и без фикса на видео ничего не заработает.

[ProxyDev]

Cant you put a txt file in description

Something went wrong, please help me see~thank you~~!
