ISM330DLC data rate for higher precision

We understood the ODR and correlated filtering. A following micro-controller application performs further filtering with averaging values to 10 per second. Aimed is calculating an angle derived from the rotational speed. Precision should be about or ...

LIS2DW12 fails to issue fifo interrupt sometimes

I'm setting up LIS2DW12 to 100Hz, low power mode 1, fifo threshold 30 and fifo interrupt on INT2.When interrupt is received by MCU (STM32L4 here) i readout register 0x2F to know how much samples is to retrieve, then retrieve them all by issuing read ...
