Calibration settings
|
|||||||
The
calibration dialog is used to set the calibration settings for the current
device. |
|||||||
Function |
Description |
||||||
|
Shows/selects
the current calibration style. Each device can have more that one calibration
style which can be calibrated independently. Calibration styles can be
invoked/switched from an application, a toolbar or the UPDD activator. |
||||||
|
Add a
new calibration style. |
||||||
|
Remove
the selected calibration style. |
||||||
|
Indicates
the number of calibration points. The number of points determines the
calibration pattern used. 2 points uses the raw pointer device data, 4, 9 and
25 uses a calibration algorithm best suited to non-linear data whereas the
other patterns are best suited to linear data. If the device supports
EEprom calibration storage, and the EEProm option is enabled in this dialog
then the number of calibration points available will be restricted to those
allowed by EEprom calibration. |
||||||
|
Indicates
the percentage margin in from the edge of the visual display area from which
to draw the calibration points. |
||||||
|
Specifies
the number of seconds to wait for a calibration touch before canceling the
calibration procedure. 0 = no timeout. |
||||||
|
If shown
implies that calibration data can be stored in the controllers EEPROM. If
enabled the calibration data is stored on the controller. In some case this
will effect the calibration options available. E.g. some EEPROM storage
procedures will dictate the number and position of the calibration points. |
||||||
|
If
enabled a calibration check dialog is shown at the end of the calibration
procedure. The calibration confirm button must be selected (with the touch
screen!) if the new calibration data is to be used. |
||||||
|
If enabled
a beep will be generated on calibration touch. |
||||||
Once
the calibration settings have been defined as required the device can be
calibrated by invoking the calibrate option from the UPDD Console control
area, as shown below: |
|||||||
|
Invoke calibration procedure for the current device. Calibration points are shown to be touched. The ESC key can be used to cancel calibration if required. Calibration will timeout if calibration points are not touched within the specific timeout period. |
