# Controller firmware settings
This firmware page describes the firmware options for the ZXY100 controller range.
Basic Settings Tab |
| 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.
