General Touchscreen Properties:
|
|
|
|
Optional properties for Touchscreens:
|
|
- touchscreen-size-x : horizontal resolution of touchscreen
|
|
(in pixels)
|
|
- touchscreen-size-y : vertical resolution of touchscreen
|
|
(in pixels)
|
|
- touchscreen-max-pressure : maximum reported pressure (arbitrary range
|
|
dependent on the controller)
|
|
- touchscreen-fuzz-x : horizontal noise value of the absolute input
|
|
device (in pixels)
|
|
- touchscreen-fuzz-y : vertical noise value of the absolute input
|
|
device (in pixels)
|
|
- touchscreen-fuzz-pressure : pressure noise value of the absolute input
|
|
device (arbitrary range dependent on the
|
|
controller)
|
|
- touchscreen-average-samples : Number of data samples which are averaged
|
|
for each read (valid values dependent on the
|
|
controller)
|
|
- touchscreen-inverted-x : X axis is inverted (boolean)
|
|
- touchscreen-inverted-y : Y axis is inverted (boolean)
|
|
- touchscreen-swapped-x-y : X and Y axis are swapped (boolean)
|
|
Swapping is done after inverting the axis
|
|
- touchscreen-x-mm : horizontal length in mm of the touchscreen
|
|
- touchscreen-y-mm : vertical length in mm of the touchscreen
|
