Hi,Today we implemented and tested the temperature compensation for the MPU60X0.
It works fine.By testing, we fond that the raw value where 2000 for g i.e. the range is +-16g. If we want to correct the angel zero it would be much better if the range is +-4g is used since then the value is 8000 for g.
The resolution grows from 11 bit to 14 bit. I think the default value should be set to +-4g. range. Usually we have no higher values than 2-3g for our kind of aircraft. Heinrich
