I've started on some documentation for the RF12 driver and the Ports library. You can see the first results over here:
This is definitely neither the ultimate page markup nor the definitive URL for the documentation. I'll probably go for some sort of navigation sidebar with these pages on the right, integrated into the jeelabs.org website somewhere.
Basic docs for RF12 and Ports are done. The more interesting PortI2C and RemotePort classes are still to do.
Comments and suggestions welcome. It takes a fair amount of work to do this, so it better be correct and useful!
