ISM330 - 416.0f Hz ODR is used consistently across multiple motion detection features

Hi everyone!

What is the benefit of setting the accelerometer ODR to 416.0f Hz when setting up the motion detection features? All motion detection features use this value. Why?

An example would be the 6D Orientation detection:

int32_t ISM330DHCX_ACC_Enable_6D_Orientation(ISM330DHCX_Object_t *pObj, ISM330DHCX_SensorIntPin_t IntPin)
{
  /* ... */
  /* Output Data Rate selection */
  if (ISM330DHCX_ACC_SetOutputDataRate(pObj, 416.0f) != ISM330DHCX_OK)
  {
    return ISM330DHCX_ERROR;
  }
  /* ... */
}

Why was this 416.0f Hz value chosen? I cannot find this in the driver documentation or anywhere else. Is this written down somewhere?

Thanks!

Hi @mfo ,

416Hz is an example ODR for alignment with the examples on the application note.
You can modify it according to what is written on AN, for example for some features (single and double tap) 416Hz is the minimum recommended ODR.
