The GUI also gives read/write access to the registers embedded in the LIS302DL device

and allows a single read of the acceleration data measured by sensor.

MEMS pointer

This section describes how to use a simple pointer application, which utilizes acceleration

data provided by the LIS302DL MEMS 3-axis linear accelerometer to control the position of

a pointer on the screen of the PC. The software provided with the kit allows the EK302DL

Evaluation Kit board to be used as an inertial mouse, where the tilt of the board is translated into

movement of the pointer. The board also emulates the left and right buttons of the mouse.

GUI description

The GUI window (see Figure 22) is divided into two sections. The top section contains the

main controls to open the connection to the evaluation kit and to start/stop the data

acquisition. The bottom section contains the pointer application controls.
