TSHARC™ Driver - Calibration (Cont’d)
Calibration Targets
Hampshire’s calibration targets have been designed to help you calibrate your touch
screen overlay as accurately as possible. Take your time and deliberately touch the
center of each calibration target as they appear on your screen. The center of each
calibration point is where the arrows come together. Because you must calibrate the
edge of the display during some calibration routines only 1/2 of the target is displayed.
This is because the remaining portion of the target would appear outside the active area
of the display. Make sure that you touch the point on the target where the arrows come
together. This will be on the outside edge of the display active area.
Multi-Monitor (single display driver card)
Hampshire’s TSHARC touch screen controllers will allow you to attach more than one (up
to eight as determined by the video card) touch screen monitor to a computer system.
To use this feature, you must have a display driver card that supports more than one
monitor, and you must have separate TSHARC touch screen controllers for each monitor
on separate com ports. You may also mix and match your com ports for the desired
configuration. For example, you may have a touch screen on com 1 and another one on
com port 2, or you may have one on your PS/2 port and another on a serial port.
To stretch the display across more than one display, enter the minimum and maximum
pixel resolution of the combined displays. Example: two monitors both set for 640x480
resolution. To stretch the touch screen set the x min to: 0 max = 1280 set the y min to:
0 and y max to 960.
NOTE: If you are displaying the same image on both touch screen displays it is not
necessary to use these features. Simply choose the touch screen controller location
that you wish to calibrate and run the calibration routine. This must be done for each
controller attached to the system.
