LIS2DW12 not recongnizing movement

Hello ,

I am working with accelerometer LIS2DW12, when I move the device very very slowly I do not see that an INT1 interrupt being raised. However, when I move the device in regular speed I DO see the interrupts.

Can you tell me why is that?

(the movement includes - moving from side to side for a ragular INT1, and flipping to get orientation change)

Thank you

Hi, might this be related to the fact that you are not accelerating, but just moving to a constant speed, so that the acceleration is zero (and no interrupt is raised)? Or to the interrupt duration that is too low? Maybe check also the datasheet for this https://www.st.com/resource/en/datasheet/lis2dw12.pdf.
