-General Touchscreen Properties:
-
-Optional properties for Touchscreens:
- - touchscreen-min-x : minimum x coordinate reported (0 if not set)
- - touchscreen-min-y : minimum y coordinate reported (0 if not set)
- - touchscreen-size-x : horizontal resolution of touchscreen
- (maximum x coordinate reported + 1)
- - touchscreen-size-y : vertical resolution of touchscreen
- (maximum y coordinate reported + 1)
- - touchscreen-max-pressure : maximum reported pressure (arbitrary range
- dependent on the controller)
- - touchscreen-min-pressure : minimum pressure on the touchscreen to be
- achieved in order for the touchscreen
- driver to report a touch event.
- - 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
-
-Deprecated properties for Touchscreens:
- - x-size : deprecated name for touchscreen-size-x
- - y-size : deprecated name for touchscreen-size-y
- - moving-threshold : deprecated name for a combination of
- touchscreen-fuzz-x and touchscreen-fuzz-y
- - contact-threshold : deprecated name for touchscreen-fuzz-pressure
- - x-invert : deprecated name for touchscreen-inverted-x
- - y-invert : deprecated name for touchscreen-inverted-y
