“Map Browsing” tab

The Map Browsing tab (Figure 17) demonstrates the possibility of using the acceleration

data obtained from the sensor to scroll a map (or another type of document) on the screen.

“Interrupt” tab

The Interrupt tab (Figure 18) provides a tool for evaluating the interrupt generation features

of the LIS302DL 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 of the two independent interrupt sources of the device.

Conversion boxes are located on the right most side of the THS and DURATION registers

(ref 1). These boxes are intended to show, respectively, the threshold value expressed in mg

and the duration value converted in msec for better readability and understanding. On the

bottom side of the window (ref 2), the content of the FF_WU_SRC register is reported for an

immediate check of its content.
