I am using the ADIS16223 to collect X Y Z values. It is running in factory default mode (As shipped)
I get 1024 X Y and Z values (See below)
Normally with an accelerometer gravity make one of the values much larger than the other two when the unit is still and placed flat on a desk. But with this unit X,Y and Z seem to be in a similar range. Am I reading the values correctly and if so how does this unit take gravity into account when you change its orientation?
