“FFT” tab
The FFT tab
The spectral data are updated every sample and are calculated on a 64-sample moving
window.

“Interrupt” tab
The interrupt tab
of the LIS331DL MEMS sensor. In this section of the GUI it is possible to configure the
characteristics of the inertial events that must be recognized by the device and to visualize,
in real-time, the level of the two interrupt lines together with the acceleration signals that are
measured by the device.
The GUI provides direct access to the registers (INT_CFG, INT_SRC, THS and duration)
that allow the configuration
device. Conversion boxes are located on the right-most side of the THS and DURATION
registers
value expressed in mg and the duration value converted in msec for better readability and
understanding.
Finally, two buttons are provided for each interrupt line to set the suggested default values
for free-fall and wakeup detection. Those buttons are marked “Set FreeFall Default” and “Set
Wake Up Default”, respectively
(Figure
(Figure
21, ref 2). These boxes are intended to show, respectively, the threshold
(Figure

(Figure
