LIS2DH sometimes does not update the XYZ data

I am using LIS2DH to detect the tilt angle of a vessel. Sometimes the XYZ reading will freeze, and not update anymore, the only way to reset it is to power on/off the system.

MP34DT05-A current consumption

Hi ST team,I use MP34DT05-A microphone in my design and I measure an addition of ~8.5mA to the average consumption current while the microphone is active.The datasheet specifies 650µA consumption in normal mode, and up to 10mA short-circuit current.S...

Resolved! How is ST recommending the use of MEMS Accelerometer for Vibration Sensing applications with Sensor Resonant Frequency as low as 2.4kHz for ISM330DCHX & similarly others?

I am surprised to see half of the MEMS sensor datasheet do not mention sensor resonant frequency. Sensor Noise values feel misleading as we have no clue what noise are we going to receive in our shipment. Also, noise levels are not documented well ei...

Resolved! Does HP_REF_MODE in lis2dw12 have any effect if FDS in CTRL6 is set to 0 (low-pass filter path selected)?

From this picture in application note looks like HP_REF_MODE should not have any effect to the output data when purple path is selected. But in tests we see differences in output data with and without HP_REF_MODE set to 1.
