Description:
|
||
|
|
Event generated when channel passes one of the four thresholds
|
||
|
|
in each direction (rising|falling) and a zone change occurs.
|
||
|
|
The corresponding light zone can be read from
|
||
|
|
in_illuminance0_zone.

Description:
|
||
|
|
Specifies the value of threshold that the device is comparing
|
||
|
|
against for the events enabled by
|
||
|
|
in_illuminance0_thresh_either_en (0..255), where Y in 0..3.
|
||
|
|
|
||
|
|
Note that threshY_falling must be less than or equal to
|
||
|
|
threshY_raising.
|
||
|
|
|
||
|
|
These thresholds correspond to the eight zone-boundary
|
||
|
|
registers (boundaryY_{low,high}) and define the five light
|
||
|
|
zones.

Get the current light zone (0..4) as defined by the

in_illuminance0_threshY_{falling,rising} thresholds.

Description:
|
||
|
|
Set the output current for channel out_currentY when in zone
|
||
|
|
Z (0..255), where Y in 0..2 and Z in 0..4.
|
||
|
|
|
||
|
|
These values correspond to the ALS-mapper target registers for
|
||
|
|
ALS-mapper Y + 1.
|
||
|
|
|
||
|
|
Note that out_currentY_raw provides the current for the
|
||
|
|
current zone.
