The backlight brightness control operates at three different levels for the
|
||
|
|
adp5520 and adp5501 devices: daylight (level 1), office (level 2) and dark
|
||
|
|
(level 3). By default the brightness operates at the daylight brightness level.

is at one of the three levels (daylight, office or dark). This

is an input code between 0 and 127, which is transformed to a

value between 0 mA and 30 mA using linear or non-linear
|

algorithms.
