Right side: main controls
The buttons on the right side of the GUI and their related functions are described below:
● Connection control - Selects the COM port on which the EK board is connected.
● Acquisition control - Starts and stops acquisition.
● Exit - Exits the MEMS Pointer Demo application.
Left side: pointer application controls
The controls on the left side of the GUI and their related functions are as follows:
● Left button/right buttons - Indicates when the left/right button on the evaluation kit is
pressed.
● X/Y-position - Shows the current 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 axes as depicted in
Figure 23.
● Tilt control - Allows the user to select the direction of the vertical displacement on the
screen vs. the direction in which the board is tilted. For example, by selecting “Up” the
pointer will move upward when the evaluation kit is tilted forward. Conversely, by
selecting “Down” the pointer will move downwards when the board is tilted backward.
● Pointer speed - Sets the sensitivity of the pointer to the inclination of the board.
