How does the pinout of the clickwheel work?

Ipod click wheel C implementation

Would it be possible to repurpose the click wheel on an Ipod 7th generation for a homebrew project like this? I'm not sure how hard it would be to reverse engineer, but if the pinout is the same or similar I think this could be a really cool project!
