If there's another source of documentation out there, I'd be delighted to know about it. So far all of my learning has been controlling simple IC chips as I dip my toes into the world of micro-controllers for the second time. Last time my experience ended in frustration due to a lack of clear documentation of how to control the micro-controller parts from the coding language given (C in this case).

I've been happily avoiding that outcome with all of the -help options and the straight forwardness of linux (and google's help), but I've started growing concerned that when I finally move up to controlling more complex things it's going to fall apart.

Let me know if there's any additional documentation out there you folks are using.
