6.1.1

Right Side: Main Controls

The buttons present on the right side of the GUI and their related function are described

hereafter:

–

Connection control: selects the COM port on which the EK board is connected to.

–

Acquisition control: starts and stops the acquisition.

–

Exit: exits from the MEMS Pointer Demo application.

6.1.2

Left Side: Pointer Application Controls

The controls present on the left side of the GUI and their related function are the followings:

–

Left Button/Right Buttons: inform on whether the left/right button present on the

Evaluation Kit is pressed.

–

X/Y-Position: shows the actual x/y coordinates of the mouse pointer on the PC

screen.

–

X/Y-Deg: shows the tilt of the Evaluation Kit along the X and Y directions which are

defined as depicted in Figure 24.

–

Tilt Control: allows to select the direction of the vertical displacement on the

screen Vs. the direction in which the board is tilted. In particular, by selecting UP

the pointer will move upward by forward tilting the Evaluation Kit. Vice versa, by

selecting DOWN the pointer will move downwards whenever the board is tilted

backward.

–

Pointer Speed: sets the sensitivity of the pointer to the inclination of the board

Figure 24.
