LIS2DW12 slow activity detection

[ludovic tramart]

Hello everybody,

In the AN5038 it is well described how to setup the internal state machine to detect activity, but it has does not fit my need:

If I have my  product in my hand, I want detect slow motion in 3 XYZ axes, but if my product is on my desk and I hit the desk with my hand, I do not want it to detect it.

and right now, what I have is the opposite, any idea where to start from? I do not have any external CPU, I want to use the internal state machine only.

Hi @ludovic tramart ,

You can try to increase the WAKE_UP_DUR to avoid to detect the spikes due to the hit on the desk.
