Detecting a short isolated event using lsm6dso32x

Hi,

I'm trying to use LSM6DSO32X to detect a short (<5ms) event isolated by at least 100ms from other events (before and after). It's on the Y axis and with a threshold of 500mg. I'm not having any luck setting up a single TAP event or by using FSM.

Any advice would be appreciated.

Hi @IRogo.1​ ,

Welcome to ST Community!

You can't use FSM because it works up to 104 Hz and 5 ms means to work at least at 200Hz.

If your signal is like a tap you can use the TAP Algorithm but considering the limited signal duration you need to set ODR accelerometer at least at 400Hz.

You can use Unico GUI to try the tap settings.
