Controller firmware settings

This firmware page describes the firmware options for
the ZXY100 controller range. |

This page lists the basic firmware settings that can be
modified during the set up of the touchscreen. |
||||||
Hardware, Firmware and Bootloader version |
This information is located at the top of the window and
shows the version numbers for the current Hardware release, Firmware release
and Bootloader release that the controller is programmed with. Hardware: ZXY-100.00
Firmware: XXX-YY
Bootloader: X.YY |
||||||
Sensitivity |
The sensitivity of the touchscreen is controlled using
the Coarse sensitivity and Threshold parameters. The Coarse sensitivity can be changed between Option 1
to 4. This should be initially used
to set the overall coarse sensitivity of the sensor with the different
options relating to the sensor glass/overlay glass thickness used (guideline
glass thickness is displayed in millimetres along side each Option 1 to 4).
Increasing the Coarse Sensitivity will make the touch sensor more sensitive
to an applied touch. The Threshold control can then be used to set the fine
sensitivity of the sensor. The Threshold
can be changed between a value of 12 and 100. Increasing the Threshold will make the
sensor less sensitive to an applied touch and decreasing the threshold value
will make the sensor more sensitive to an applied touch. Please
note: the Threshold control has the inverse affect to that of
the Coarse sensitivity control. |

The Test Sensor button launches the Test page. This page displays the individual signal
levels of each of the wires embedded within the sensor. This graph can be used to determine the optimum settings
for the Coarse Sensitivity and Threshold. For the touchscreen controller to recognise an applied
touch event, at least one wire (blue bar on graph) from the X-Wire and one wire
level from the Y-Wires need to be above the Threshold value. To choose the correct value for Threshold, apply a touch
to the sensor moving your finger left to right, then top to bottom over the
sensor. Note the peak wire levels on
each of the wires and use this to choose your setting. The Threshold setting should be several
units below the minimum peak wire level observed across the screen. Please
note: touch operation
is disabled when the Sensor page is open.
The Test Sensor page can be terminated by: 1)
Pressing the Escape key on a connected keyboard. 2)
Use a connected mouse to press the Close button
(bottom right hand corner of the page). 3)
Holding a stationary touch on the test screen for
10 seconds. The page can also be used as a sensor debug tool: 1)
The test page can be used to observe any abnormal
noise levels that may have an influence on the embedded wire array – this
would be shown as random wire levels above 2 to3 across all wires on the
graph. 2)
On a fully operational sensor all of the
individual wires in the X and Y axis should show a response when an applied
touch is dragged from left to right and top to bottom across the sensor. An abnormal wire operation would be
observed as a moving bar on the graph. |
||||||
|
This forces the touchscreen controller to normalise all
the wire levels within the sensor and take these normalised levels as new
reference values for processing information. |
||||||
|
This will initiate a reset of the touchscreen controller. After execution the controller may take a
few seconds to re-establish full operation to an applied touch. |
||||||
|
This restores the factory default settings of the
touchcsreen controller. |
||||||
|
The dual touch icon will only be visible when using a
Windows 7 operating system. The dual-touch icon can be checked to enable a dual
touch (two independent co-ordinates) output from the controller. |

This is an Engineering Mode Only Page and by default
this page is hidden from the user and can only be accessed by contacting the Zytronic
Technical Support Team. This page is
only required in rare scenarios where access to engineering mode settings is
required |

The cancel button will discard any parameter changes
made. |
||||||
|
The Apply button will execute any parameter changes made
without exiting the page. |
||||||
|
The OK button will save all settings and exit the
current page. |
