1General Touchscreen Properties:
2
3Optional properties for Touchscreens:
4 - touchscreen-size-x : horizontal resolution of touchscreen
5 (in pixels)
6 - touchscreen-size-y : vertical resolution of touchscreen
7 (in pixels)
8 - touchscreen-max-pressure : maximum reported pressure (arbitrary range
9 dependent on the controller)
10 - touchscreen-fuzz-x : horizontal noise value of the absolute input
11 device (in pixels)
12 - touchscreen-fuzz-y : vertical noise value of the absolute input
13 device (in pixels)
14 - touchscreen-fuzz-pressure : pressure noise value of the absolute input
15 device (arbitrary range dependent on the
16 controller)
17 - touchscreen-average-samples : Number of data samples which are averaged
18 for each read (valid values dependent on the
19 controller)
20 - touchscreen-inverted-x : X axis is inverted (boolean)
21 - touchscreen-inverted-y : Y axis is inverted (boolean)
22 - touchscreen-swapped-x-y : X and Y axis are swapped (boolean)
23 Swapping is done after inverting the axis
24 - touchscreen-x-mm : horizontal length in mm of the touchscreen
25 - touchscreen-y-mm : vertical length in mm of the touchscreen
