True Colour Sensor Calibration
The major issue while using this sensor is calibration, and the lack of documentation provided by the supplier.
Each of the four channels has two parameters:
So all this sounds pretty conceptual, and no hint whatsoever is given about what's better:
I tested and plotted on 3D a wide range of combinations of capacitance values and integration times:
Finally, a corrective coefficient is computed to ensure all the RGB measures have the same value for a white object.
