Figure 1: TouchPanel Controller additional board
How to connect the board?
The TouchPanel Controller additional board can be easily connected to a development system via an IDC10 connector
CN1 that is connected to a port of the development system. Connection between the additional board and a touch panel
is established via the CN2 connector provided on the additional board.
How to use the board?
A touch panel is a transparent touch sensitive foil. In order to register any touch, it is necessary to connect the touch
panel to this additional board. The principle of the touch panel operation is based on the voltage change caused by a
touch or pressure applied to the touch screen. Voltage change detection is enabled due to the touch screen design. It is
composed of two exible sheets coated with a resistive material separated by an air gap. In order to detect a contact, it
is necessary to apply voltage to one of these two sheets (DRIVEA for example). When contact is made, the two sheets
are pressed together and the second sheet measures the voltage in the pressed point as a distance along the rst
sheet. The measured distance is referred to as X-axis (BOTTOM). As soon as this data is aquired, the same voltage is
applied to the second sheet (DRIVEB). Now, the rst sheet measures the distance referred to as Y-axis (LEFT).
