- 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.
- What: /sys/.../events/in_illuminance0_threshY_hysteresis
- Date: May 2012
- KernelVersion: 3.5
- Contact: Johan Hovold <[email protected]>
- Description:
- Get the hysteresis for thresholds Y, that is,
- threshY_hysteresis = threshY_raising - threshY_falling
- What: /sys/.../events/illuminance_threshY_falling_value
- What: /sys/.../events/illuminance_threshY_raising_value
- Date: April 2012
- KernelVersion: 3.5
- Contact: Johan Hovold <[email protected]>
- 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.
- What: /sys/bus/iio/devices/iio:deviceX/in_illuminance0_zone
- Date: April 2012
- KernelVersion: 3.5
- Contact: Johan Hovold <[email protected]>
- Description:
- Get the current light zone (0..4) as defined by the
- in_illuminance0_threshY_{falling,rising} thresholds.
- What: /sys/bus/iio/devices/iio:deviceX/out_currentY_currentZ_raw
- Date: May 2012
- KernelVersion: 3.5
- Contact: Johan Hovold <[email protected]>
- 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.
