Controller firmware settings

Version 1.0 – 17th April 2012

 

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.
