 Bigger Bigger  Smaller Smaller  Reset Reset

The code was written for version 0011 of the IDE. You are running version 0012.

There are a few fixes floating around on the forum. Check the last post here:

But also do some searching around.

ladyada has a version of servotimer1 that works with 0012 here: http://www.ladyada.net/media/mshield/ServoTimer1-fixed.zip

No that code worked fine for me, make sure you've got the NECIR library installed.

 Bigger Bigger  Smaller Smaller  Reset Reset

I have the NECIRrcv.h library added to the Arduino sw but still get compiling errors when compiling the small program that is listed above:

In file included from C:\Program Files\arduino-0012\hardware\cores\arduino/WProgram.h:4,

c:/program files/arduino-0012/hardware/tools/avr/lib/gcc/../../avr/include/stdlib.h:80: error: expected unqualified-id before 'int'

c:/program files/arduino-0012/hardware/tools/avr/lib/gcc/../../avr/include/stdlib.h:80: error: expected `)' before 'int'

......

c:/program files/arduino-0012/hardware/tools/avr/lib/gcc/../../avr/include/stdlib.h:176: error: '__compar_fn_t' has not been declared

In file included from C:\Program Files\arduino-0012\hardware\cores\arduino/WProgram.h:6,

Do I need some other library? WProgram?

Please help... I am totally new and "desperately" need a working NEC IR receiving sketch.

Thanx...

I think I can take two things from this post:

1. Include #undef int  somewhere

2. * Moved insertion of #include <WProgram.h> to after any comments and #include statements in the main sketch file.  This means that an #include <stdlib.h> now works.

If one of these or both are supposed to "do the job" where do I have to change code then? In "NECIRrcv.h" or in the "main sketch calling "NECIRrcv.h"?

Hi, I am a noob at Arduino en English... smiley-razz

And I have a problem, I use a IR Photodiode for this library, does that work? And do you must connect the Photodiode to a analog pin or a digital?

The IR signal from a remote control has a carrier frequency, usually around 38kHz or 40kHz.  This helps filter out noise because the system can ignore any signal that's not at the carrier frequency.  

The IR modules discussed in this thread strip out the carrier and just output the signal.  If you use a straight photodiode connected to an Arduino pin, the pin will see the carrier frequency, and you will have to deal with that signal.

You would connect it to a digital input, but connecting it isn't completely straightforward.

Hey Lighty,
To be able to receive and decode commands from remote controls you would need an IR receiver, like this one:
http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=751-1223-5-ND
This is an IC that does much more than a photodiode.
Signals from this IR receiver is digital, so you connect it to a digital input.
Read this:

or follow this thread for another solution:

Here are some mirrors where you can download the necirrcv file.

Modernators, please add these to the begin post.

Had same compiler problems as Jacobson and others.

Finally got this working on Duemilanove with ATMEGA328 and using Arduino 16.

Secret was to add: #include <WProgram.h> to main sketch like this:

Code:

// look for IR codes and print them as they are received

#include <WProgram.h>
#include <NECIRrcv.h>
#define IRPIN 4    // pin that IR detector is connected to

NECIRrcv ir(IRPIN) ;

void setup()
{
  Serial.begin(9600) ;
  Serial.println("NEC IR code reception") ;
  ir.begin() ;
}

void loop()
{
  unsigned long ircode ;
  
  while (ir.available()) {
    ircode = ir.read() ;
    Serial.print("got code: 0x") ;
    Serial.println(ircode,HEX) ;
  }
}


Works like a charm!

Regards to all,

If you are going to be using this library in more than one sketch, instead of adding  #include <WProgram.h> to each sketch that uses the library, you can add it as the first line in the NECIRrcv.h file.
