AVR-Chat

I have used the Memsic 2D accelerometers in a toy magic wand for
many years. The Memsic part is very similar to the AD202, but
cheaper and slower.  The accelerometer, coupled to an AVR,
performs tilt and motion sensing.  The analog interface code is
straight-forward, and I'd be happy to share mine (assembly).
