Optional properties:
- upisemi,glass-coef: glass attenuation factor - compensation factor of
resolution 1000 for material transmittance.
+
- upisemi,dark-ths: array of 8 elements containing 16-bit thresholds (adc
counts) corresponding to every scale.
+
- upisemi,upper-dark-gain: 8-bit dark gain compensation factor(4 int and 4
fractional bits - Q4.4) applied when light > threshold
+
- upisemi,lower-dark-gain: 8-bit dark gain compensation factor(4 int and 4
fractional bits - Q4.4) applied when light < threshold
+- upisemi,continuous: This chip has two power modes: one-shot (chip takes one
+ measurement and then shuts itself down) and continuous (
+ chip takes continuous measurements). The one-shot mode is
+ more power-friendly but the continuous mode may be more
+ reliable. If this property is specified the continuous
+ mode will be used instead of the default one-shot one for
+ raw reads.
+
If the optional properties are not specified these factors will default to the
values in the below example.
The glass-coef defaults to no compensation for the covering material.
