Accumulation
When you increase the accumulation value, you reduce the noise as well as the measurement
rate. Depending on your application, a reduction of the noise might be more important than a
high measurement rate.
Oversampling
When you increase the accumulation value, you increase the resolution (accuracy) but you
reduce the measurement rate. Depending on your application, a higher resolution might
be more important than a high measurement rate.
Points
Determines the maximum detection range. It also has an impact on the processing load
since it impacts the number of sample points to process for each segment.
Threshold offset
The threshold offset is a value that modifies the detection amplitude threshold.
A default detection threshold table was determined to provide robust detection and
minimize false detections caused by noise in the input signal.
Figure 16 presents the threshold table for a light source intensity of 16. This table is
effective when the threshold offset value is 0.
