description:
|
|
Pen-down threshold for the touchscreen. This is a value
|
|
between 1 and 4096. It is the ratio between the internal reference voltage
|
|
and the measured voltage after the plate was precharged. Resistance between
|
|
plates and therefore the voltage decreases with pressure so that a smaller
|
|
value is equivalent to a higher pressure.
|
|
|
|
fsl,settling-time-ns:
|
|
description:
|
|
Settling time in nanoseconds. The settling time is before
|
|
the actual touch detection to wait for an even charge distribution in the
|
|
plate.
