Acceleration and velocity files are different lengths. Is acceleration craping out?
I used MetaBase (on Android) to configure the sensor to record the accelerometer and gyroscope at the same time, both at 100 Hz. For test data I rotated the sensor by hand back and forth around each of the three axes, y then x then z.
The csv for acceleration has ten fewer rows than the one for the gyro. Is that normal? At 100 Hz it's not much of a difference and I suppose it could be accounted for by the time it takes the first file to close.
It also looks like the accelerometer maybe stopped reacting after the x rotations. Or am I not interpreting the values correctly (I'm new to these sensors and kinematics in general)? At least it's different than the other two rotations. Here is a plot of the raw values from the csv files.
