Operation
Figure 3−1. Human Interface Screen
This screen reflects the touch screen from the TSC2100EVM. The status bar
at the bottom of the screen is divided into four sections and shows the status
of communication between the PC and the EVM. Starting from the left, the first
section shows the status of the connection; if an error in communication
occurs, an error message appears here, otherwise it looks as shown in
Figure 3−1. The final section, on the right side of the status bar, shows the
number of readings per second being taken from the touch screen.
The touch screen box on this screen is updated when a touch is detected on
the touch screen. As the touch screen is drawn upon, the motion on the touch
screen is translated into pixels on the screen. The software takes X, Y, and Z
readings, which are shown at the top of this box. As the touch pressure is
increased, the pixel size increases; a lighter touch results in smaller pixel
sizes.
The display can be cleared by pressing the Enter or Backspace key on the PC
keyboard.
3.5.2 Data Acquisition Screen
The data acquisition functions of the TSC2100 can be accessed on this screen
as shown in Figure 3−2.
