Mounting the Capacitive Touch Screen
There are a number of methods that may be used to mount your touch screen depending upon your application and
the recommendations of your sensor supplier. In all cases it is important that you do not make any electrical
connections between the touch sensor and the integrated system. Please contact your sensor manufacturer for
specific mounting recommendations.
The sensor tail often experiences more electrical noise than the sensor itself. Special care should be taken when
considering the tail mounting of the sensor. Please contact your sensor manufacturer for specific instructions
regarding the sensor tail.
In all cases, take special care to mount the touch screen in such a manner as to eliminate any screen shift or
movement during operation. The C-Ray controller gathers environmental variables at power-up. Any changes to the
touch screen position during use can negatively influence the performance of the system.
Connecting the Touch Screen
The TSHARC C-Ray, capacitive controller supports back shielded, non-back shielded and shielded tail capacitive
touch screen overlays. Check the touch screen tail and verify the pin-out of the touch screen before you connect the
touch screen to the controller. If the touch screen has a back shield or a shielded tail a connection must be made to
the 3 rd pin of header H4. Failure to connect a shielded touch screen or tail will cause the controller to malfunction.
This connection is shown in Fig. 3.0.
Note: Microchip’s touch screen mapping is consistent with all operating system display mapping specifications. Most operating
systems draw the screen from upper left to lower right.
