3.4.1.1 Touch Screen Section
The touch screen box on this screen will be updated when a touch is detected on the
touch screen. As the touch screen is drawn upon, the motion on the touch screen will be
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 Delete keys on the PC keyboard.
3.4.1.2 Keypad Section
The keypad functions of the TSC2200 are controlled from this section of the screen. As
keys on the keypad of the EVM are pressed, the keypresses are displayed in the display
near the top of this box. The keymap shown here will also reflect keypresses on the EVM.
The display can be cleared by pressing the Clear button in this box.
Individual keys can be masked by clicking on the key in the keymap on this screen. The
key label will change to an "X" to reflect that the key is masked. When a key is masked,
pressing that key on the keypad on the EVM will not result in the keypress being detected.
To unmask a key which was masked, simply click on the key in the keymap again, and
the key label will return to its corresponding value.
The debounce time for the keypad can be set using the slider in this section. The
debounce time can range from 2ms to 120ms. Note that using short debounce times will
result in a single keypress generating multiple keypress events.
