Re: BEI Gyrochip AQRS - just counting up?

I'd try defining/reading it as a straight raw analog input through the cRIO to begin with, just to see the raw data it's sending without the gyro software massaging.

See if it returns close to 2.5v while at rest.

It's probably the 75 degress per second model, so it'll be good on the straight and narrow, but not so good on turns.

P.S.
What gain did you use when you defined it as a gyro, e.g., .03 volts/degree/sec?
How did you wire the three pins, since the order might not be what you expected (pin A= +5v, pin B=ground, pin C= analog signal (.25 to 4.75v))?

These can be damaged by drops or other sudden shocks.
