Why can't I compile the AtTouch Library

Projects Programming

I'm trying to use the AtTouch Library:

http://n0m1.com/2011/08/01/attouch-library-for-arduino-and-the-at42qt1070/

When I compile the included example AtTouch_press - I get a ton of errors, included below.

Has the IDE changed since this library was released, Is something up with my system?

Yes, it has changed - at a minimum you'll need to replace

#include "WProgram.h"

with

#if defined(ARDUINO) && ARDUINO >= 100
  #include "Arduino.h"
#else
  #include "WProgram.h"
#endif

In the libary code (as will as add conditional compilation around the Wire.send calls to use Wire.write for Arduino 1.0 and later.

Thanks, that cleared up a lot of errors but there are still some remaining - any more suggestions?

The .h file needs to #include <Arduino.h>

That's where all the definitions are.

So in AtTouch.h, I've tried replacing

#include "WProgram.h"

with

#if defined(ARDUINO) && ARDUINO >= 100
  #include "Arduino.h"
#else
  #include "WProgram.h"
#endif

and also tried

#include <Arduino.h>

But I still get the errors, I'm sure this must be simple... What else could I be doing wrong??
