Good morning
I have many interrupts, as if HPF filter is bypassed (see log file annexed)
If I see acceleration data, they are filtered correctly (see Z axis).
What's wrong with my settings?

Hi Carlo,
The motion detection function is an analysis of low-pass filtered data only, even if the high-pass filter is enabled (HPF_OUT = 1). I would recommend using the transient detection function instead as it analyzes high-pass filtered data unless the HPF_BYP bit is set. For more information on the transient detection function including example register setting please refer to the AN4071.
I hope it helps.

Tomas
