20.0. Touch Panel
20.0. Touch Panel
The touch panel is a thin, self-adhesive, transparent, touch-sensitive panel. It is placed over a GLCD display. Its main function is to
register pressure at some specifi c display point and to forward its coordinates in the form of analog voltage to the microcontroller.
Switches 5, 6, 7 and 8 on the DIP switch SW13 are used for connecting these two units.
Figure 20-1: Touch panel
Figure 20-1 shows how to place a touch panel over a GLCD display. Make sure that the fl at cable is to the left of the GLCD display,
as shown in Figure 4.

Figure 20-3: Placing touch panel
Figure 20-3 shows in detail how to connect a touch panel to the microcontroller. Bring the end of the fl at cable close to the CN22
connector (Figure 1). Plug the cable into the connector (Figure 2) and press it easily so as to fully fi t the connector (Figure 3). Now, a
GLCD display can be plugged into the appropriate connector (Figure 4).
