  1. General Touchscreen Properties:
  2. Optional properties for Touchscreens:
  3. - touchscreen-size-x : horizontal resolution of touchscreen
  4. (in pixels)
  5. - touchscreen-size-y : vertical resolution of touchscreen
  6. (in pixels)
  7. - touchscreen-max-pressure : maximum reported pressure (arbitrary range
  8. dependent on the controller)
  9. - touchscreen-min-pressure : minimum pressure on the touchscreen to be
  10. achieved in order for the touchscreen
  11. driver to report a touch event.
  12. - touchscreen-fuzz-x : horizontal noise value of the absolute input
  13. device (in pixels)
  14. - touchscreen-fuzz-y : vertical noise value of the absolute input
  15. device (in pixels)
  16. - touchscreen-fuzz-pressure : pressure noise value of the absolute input
  17. device (arbitrary range dependent on the
  18. controller)
  19. - touchscreen-average-samples : Number of data samples which are averaged
  20. for each read (valid values dependent on the
  21. controller)
  22. - touchscreen-inverted-x : X axis is inverted (boolean)
  23. - touchscreen-inverted-y : Y axis is inverted (boolean)
  24. - touchscreen-swapped-x-y : X and Y axis are swapped (boolean)
  25. Swapping is done after inverting the axis
  26. - touchscreen-x-mm : horizontal length in mm of the touchscreen
  27. - touchscreen-y-mm : vertical length in mm of the touchscreen
  28. Deprecated properties for Touchscreens:
  29. - x-size : deprecated name for touchscreen-size-x
  30. - y-size : deprecated name for touchscreen-size-y
  31. - moving-threshold : deprecated name for a combination of
  32. touchscreen-fuzz-x and touchscreen-fuzz-y
  33. - contact-threshold : deprecated name for touchscreen-fuzz-pressure
  34. - x-invert : deprecated name for touchscreen-inverted-x
  35. - y-invert : deprecated name for touchscreen-inverted-y
