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. | 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.

There doesn't seem to be a way to get the actual TV resolution while using the "Default" Display. Official apps just hard-code what resolution to use depending on the current [[AM_services|OperationMode]]. | There doesn't seem to be a way to get the actual TV resolution while using the "Default" Display.

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 BH1730 outputs 2 values.

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 default values are Gain 64x and ITIME of 38 (256 - 218).
