Arduino Library for Hmc6352

As part of my Xbee sensor project, I created an object oriented API to access HMC6352 compass functionality and I decided to make it downloadable as an Hmc6352 Arduino Library.
Just unzip the file in the $arduino_home/hardware/libraries/. At the end you should end with $arduino_home/hardware/libraries/Hmc6352.

The library includes an example on how to use it (in File ⇒ Sketchbook ⇒ Examples ⇒ Library-Hmc6352 ⇒ Hmc6352.
