Controller firmware settingsVersion 1.0 – 17th

|||||||
This firmware page describes the firmware options for
this controller. Note. These setting
should be viewed on the understanding of how the controller and driver
interact to determine if a touch has occurred. The controller has a series of embedded
wires that output a constant stream of raw data co-ordinates called the ‘normal
range’, even when untouched. When
touched the range of the co-ordinates within the data will increase from
wires near the touch. The touch algorithm works by detecting the wire value changing from
the normal range of co-ordinates but at the same time has to cater for false
data movement, data spikes and the constant reassessment of wire ranges due
to environmental conditions. These settings need to be adjusted until the
right setting combination is found to give the best touch performance in any
given environment. |
|||||||
Sensitivity |
Indicates the pressure required to activate a touch.
Range 1-50 (Default 15) |
||||||
Range |
This is the lower threshold value. A wire value above this range must be
received to be processed as a touch. Range 1-50 (Default 10). |
||||||
During operation, if too
many wires report a possible touch (increasing wire level) this is considered
an error condition and triggers a software reset to clear the error condition.
The reset is triggered when a defined number of wires (Reset Threshold Wires) simultaneously pass a wire level (Reset
Threshold) |
|||||||
Threshold Wires |
Number of wires reporting a touch that indicates an
error condition |
||||||
Reset
Threshold |
Is the value over which a level is considered to be
a touch. |
||||||
|
This option displays a test sensor grid to view the
wire data and can be very useful as a diagnostics tool to help understand
data characteristics and the likely settings required. The values shown are normalized data after
processing raw data from the controller. When in this mode use the ESC key to exit. A steady touch for 10 seconds can also be
held but this is not always reliable due to fluctuating raw data seen as
touch movement. |

The close button will discard any parameter changes made
since the last apply. |
||||||
|
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. |
