Version 0.2.0
This release adds compatibility with the European Dual Analog Controller (SCPH-1180e). Hopefully the US version (SCPH-1180) will work as well, and so will the Japanese version (SCPH-1150), even though the latter has more pronounced differences (it has vibration motors, for instance) so it's hard to say. Please report.
It also adds an example that shows how the library can be used with PsxControllerShield, an Arduino shield I have designed as a safe and straightforward reference for connection of a PlayStation controller to an Arduino board.
Finally, this release addresses some compilation warnings.
