If you're interested in Parallax's powerful 8-core Propeller chips, which are a huge step up from the Basic Stamps, here's some good news: a kind soul named Jason Wood has uploaded to the Parallax site a very complete Kalman-filtered IMU code object that uses the SparkFun IMU sensor head and this ADC. You plug the three components together, and the code gives you true Angle, Rate and q_bias. For those who have tried to write their own IMU, this is a Very Big Deal.
Basically, if you want to make a Propeller-based autopilot, Jason's done most of your work. No excuses now!
BTW, there are lots of other goodies in the Parallax object library
, such as math libraries, floating point subroutines and PID routines.
