14.12 Touch Screen Pressure
The Horner XL series OCS controllers have a resistive touch screen that allows mechanically
detecting touch events. The resistive touch screen works by measuring the resistance
between two layers of conductive film.
The following are required for this feature:
Minimum Firmware Version: 15.xx or later
Minimum OS Version: 2.6.35.49
Minimum Cscape Version: 9.80 SP1

Touch Screen Pressure
NOTE: Touch creates contact between resistive circuit layers, closing a switch.
With a unique change to the touch monitoring firmware user can measure the pressure being
exerted on the touch screen. This feature has been added in some Horner XL series
controllers. This allows the OCS programmer to be notified of the touch pressure and it can
configure the pressure required to accept a touch event.
