Hello!

So I have an issue, probably an easy to answer one, with receiving the IR hex codes. The problem is that if I reset my board or plug it in/out a few times to my computer the hex codes change.

Any ideas why the hex codes are changing?

Example of pressing the same button:
irCode: FF4AB, bits: 28
irCode: FFFFFFFF, bits: 0
irCode: 1BC0157B, bits: 32
irCode: 1BC0157B, bits: 32
irCode: 1BC0157B, bits: 32

Generated by the following code:

#include <IRremote.h>  
 
const int irReceiverPin = A3;  
const int ledPin = 13;
 
IRrecv irrecv(irReceiverPin); 
decode_results results;    
 
void setup()
{
  pinMode(ledPin,OUTPUT);
  Serial.begin(9600);   
  irrecv.enableIRIn();   
}
 
void loop() 
{
  if (irrecv.decode(&results)) {   
    Serial.print("irCode: ");            
    Serial.print(results.value, HEX); 
    irrecv.resume();    
    
  }  
  delay(600); 
  if(results.value == 0xFFA25D)
  {
    digitalWrite(ledPin,HIGH);
  }
  else
  {
    digitalWrite(ledPin,LOW);
  }
}

Give us more detailed information on how you tested it.
Why and when did you reset it and what did you get before and after.
How long after reset did you try using it?
How long did you hold the button on?

Are those results are from a different sketch.

irCode: FFFFFFFF this is the repeat code for the button pushed.
