You may have a bad solder joint somewhere. I remember on one of the prototype boards I was having all kinds of problems. Turned out a little blob of solder was bridging the legs on an IC. The fact that you've got a warm/hot IC may be worth investigating -- that was one of the symptoms I found too.

The calibration code is at the end of the program IIRC. If you really
want to understand what it is doing, I suggest you look at the code
and my comments.
