    [BMX055] testing values

    Hi again,

    I was wondering how can we test values read then converted of the BMX055 ?

    I mean, when we have a sensor which measures temparture, it's easy to know if value that we have read/convert are rational, but with acceleration and angular rate, it seems too be a little bit harder !

    For acceleration, we can only test if az= 1g  then ax=1g and ay=1g ...

    But what about the gyrometer ?

    And the magnetometer ?

    Thanks

    [EDIT]  : Well, advanced test for magnetometer seems to give a good idea of the coherence of read values

    Sorry for the delayed reply.

    For accelerometer, using gravity is definitely the easiest.

    For gyroscope data, you can easily test the static case. When not moving -> 0dps. To test in motion you need a rate table.

    Testing the magnetometer is more tricky, typically done with 3 Helmholtz coils to generate a known magnetic field.
