Hi,
Like others I noticed the raw output moves around quite a bit. X values up to around +/ 50 or so. Is this oscillation normal and requires averaging/Filtering to stabilize or is this resolved by the DMP? noticed the sensor hub by TI didn't fully resolve it with their DCM.

Re: Re: MPU9150 raw output
Hi,
Looking at the X values the maximum difference from average was about 70 or so.
2g/32768 = 61ug per count
70 * 61 = 4.27mg peak which is close to the 4mg RMS noise mentioned in the spec.
I'll be looking at averaging or some type of filtering to reduce this oscillation effect though. DLPF was set at 10.
Re: Re: MPU9150 raw output
Are you referring to the accel data. Based on the spec, it can be 150 mg on the z axis, your numbers do not look off base.
