so, a maximum resolution must be kept for heading precision while the full signal range has to be measured for High "G" movements controlling ... and avoiding " non linear " ( ROFL ) - or unwanted - moves.
Thermistor is just here for best temp compensation of Gyro and Accelmeter ...
May be 8 Bits PICs, and generally Pīcs are not the best components for this kind of Games ...

In fact my UAV board has a dsPIC33F(12bit A/D) and a PIC32 and a math coprocessor for sensors (and other more sensors), maths processing, GPS parsing, coordinates algorythms, and blah blah, in fact is a full AHRS. I just want to play from conceptual small to prototype big. Lucky I have no problems on C30 and C32, I'm on the digital side of the project, not on the electronics side, as you can see by the title of this thread. But i love electronics and I'm working to try to get inside it. The board comes ready to program. My this thread was oriented to the "conceptual small" version of it.
