What: /sys/.../events/in_illuminance0_thresh_either_en |
|
Date: April 2012 |

KernelVersion: 3.5 |

Contact: Johan Hovold <[email protected]> |
|
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: |
|
Get the hysteresis for thresholds Y, that is, |
|
threshY_hysteresis = threshY_raising - threshY_falling |

|
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. |

|
Description: |
|
Get the current light zone (0..4) as defined by the |
|
in_illuminance0_threshY_{falling,rising} thresholds. |

|
Description: |
|
Get output current for channel Y (0..255), that is, |
|
out_currentY_currentZ_raw, where Z is the current zone. |

|
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.
