Colour Sensor RGB Unit (TCS3472)

Overview:

COLOUR is colour recognition unit integrated with TCS3472 chipset. As the name says, COLOUR is able to detect colour value and return RGB data as response.
Identify colour principle: The TCS3472 chipset integrated with 3*4 array of filtered photodiodes and a 16 bit analog-to-digital embedded converters. Out of the 12 photodiodes, 3 have red filters, 3 have green filters, 3 have blue filters and 3 have no filter (clear), which gives a total range of RGBA (RGB + Transparency)
When detecting the colour of an object the TCS3472 returns data from four channels: red(R), green(G), blue(B) and clear(C)(non-filtered). The response from the red, green and blue channels (RGB) can be used to determine a particular source’s chromaticity coordinates (x, y).
This Unit communicates with the M5Core via the GROVE A interface(I2C). Address is 0x29.
