MEMS pointer

This section describes the usage of a simple pointer application which employes the

acceleration data provided by the LIS3LV02DL MEMS 3-axis linear accelerometer to control

the position of a pointer on the screen of the PC. More in details, the SW provided with the

kit itself allows to employ the board provided with the EK3LV02DQ Evaluation Kit as an inertial

mouse where the tilt of the board is transformed into a movement of the pointer. The board

emulates also the left and right buttons of the mouse.

GUI description

The GUI window (see Figure 23) may be split up into two sections: the right side contains

the main controls to open the connection to the Evaluation Kit and to start/stop the data

acquisition whereas the left side is dedicated to the pointer application controls.
