Arduino IRremote library and problems

I have been trying to use this IRremote library with arduino 0018 on Mac:

But for some reason it doesn’t seem to work. And I don’t know why. When I try to run any example (included with the library) I get this:

This looks like some include file was not included in your sketch, or that you have not selected the correct board in the Tools + Board menu.

Post your sketch, and tell us about the board you have.

#3

My board is duemillanove with Atmega8, I selected atmega 8, and the correct serial port. The sketch that I am using is this (came with the library):

/*
 * IRremote: IRrecvDemo - demonstrates receiving IR codes with IRrecv
 * An IR detector/demodulator must be connected to the input RECV_PIN.
 * Version 0.1 July, 2009
 * Copyright 2009 Ken Shirriff
 * http://arcfn.com
 */

#include <IRremote.h>

int RECV_PIN = 2;

IRrecv irrecv(RECV_PIN);

decode_results 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
  }
}

Strange thing is if I try to compile this sketch for Duemillanove with Atmega328 I don’t get any errors compiling - I get errors when uploading.

#4

If your board is a Duemilanove, it has either an ATmega168 or ATmega328. If you actually selected ATmega8, that could be the cause of the problem.

The board is duemillanove and it has Atmega8 - my athega168 died so I replaced it with atmega8.

#6

Well, there is your problem. Replace the ATMege8 with the proper chip or learn how to program the ATMega8. It isn't nearly as easy as programming the ATMega168 or ATMega328.

#7

Why not? I have been using Atmega8's for some time now (because I couldn't get any Atmega168 where I live) and this is the first time I had any problem with it.

EDIT: The library appears to be using some low level "functions" and isn't written for Atmega8. Also the code is too big to fit the Atmega8. Next time I am ordering from farnell I realy have to buy a few Atmega328.
