| 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-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 |
| |
