GetAmbientLightSensorValue
No input. Before 5.x, outputs lux in float. (5.0.0+) Returns an output struct:
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x4 | bOverLimit. (u32) Equals to 1 if visible or IR light data is over 65534. |
| 0x4 | 0x4 | fLux. (float) Value in lux from the ambient light sensor. |
Note: if bOverLimit=1 and the default ALS configuration is used, the measurement of fLux should not be considered and the actual max value depends on the type of light. Ranges from 12.5K - 17.5K.
GetCurrentBrightnessSetting
No input. Returns an output u32 int of the current backlight level.
GetBrightnessSettingAppliedToBacklight
No input. Returns an output u32 int of the backlight level computed from the ambient light sensor.
IsAutoBrightnessControlEnabled
No input. Returns an output u8 bool indicating whether auto brightness is enabled.
EnableVrMode
No input/output. Used by AM_services#SetVrModeEnabled.
Sets a global state field to 0x1.
DisableVrMode
No input/output. Used by AM_services#SetVrModeEnabled.
Sets the global state field used by #EnableVrMode to 0x0.
IsVrModeEnabled
No input. Returns an output u8 bool set by the above commands.
Notes
The BH1730 outputs 2 values. Visible light and IR light. This is then calculated through an algorithm that checks for Gain, Measurement time, filter qualities and ouputs lux (max correct measurement of 100K lux). The default values are Gain 64x and ITIME of 38 (256 - 218). This allows for a max lux value of 17972 lux when visible light value is maximum and IR light is 0. When both of them are on their limit, the output is 1192 lux. The sensor is fully configurable.
