DefaultAddress return the default i2c address.

Configuration Settings.

Change this to 12 bit if you want less accuracy, but faster sensor reads At default 16 bit, each sensor sample for a given color is about ~100ms.

Light intensity range In a dark environment 375Lux is best, otherwise 10KLux is likely the best option.

Unless you want the interrupt pin to be an input that triggers sensor sampling, leave this on normal.

CONFIG1 Pick a mode, determines what color[s] the sensor samples, if any.

Sets amount of IR filtering, can use these presets or any value between = 0x00 and = 0x3F Consult datasheet for detailed IR filtering calibration.

How many times a sensor sample must hit a threshold before triggering an interrupt More consecutive samples means more times between interrupts, but less triggers from short transients.

CONFIG3 No interrupts, or interrupts based on a selected color.

If you would rather have interrupts trigger when a sensor sampling is complete, enable this If this is disabled, interrupts are based on comparing sensor data to threshold settings.
