@Gordon
Did you have some code in there that had been save()d already? That could be causing you problems I guess ...
Maybe there is some other pin (a reset pin?) that needs its state changing first...
Also aren't you supposed to wait for it to initialise at some point? You don't appear to be doing that...
The code is looking good though. It'd make a module really easily.
