Description

COLOR is a Color Light-to-Digital Converter with IR Filter. TCS3472 device provides a digital return of red, green, blue(RGB), and clear light sensing values. An IR blocking filter,integrated on-chip and localized to the color sensing photodiodes, minimizes the IR spectral component of the incoming light and allows color measurements to be made accurately.

In order to get better result, you can try to blacking the sunken area on the side with marker pen.

This Unit communicates with the M5Core via the GROVE PORTA (I2C). Address is 0x29.

Example

Arduino IDE

The code below is incomplete. To get the complete code, please click here.

/*
  Color test
    hardware: M5Stack

  please install the Adfruit TCS34725 library first ...
*/
#include <Wire.h>
#include <M5Stack.h>
#include "Adafruit_TCS34725.h"

// declaration
uint16_t clear, red, green, blue;
#define commonAnode true // set to false if using a common cathode LED

// new a object
Adafruit_TCS34725 tcs;
tcs = Adafruit_TCS34725(TCS34725_INTEGRATIONTIME_50MS,TCS34725_GAIN_4X);

// initialization
M5.begin(true, false, false);
tcs.begin();
tcs.setIntegrationTime(TCS34725_INTEGRATIONTIME_154MS);
tcs.setGain(TCS34725_GAIN_4X);

// read data
tcs.getRawData(&red, &green, &blue, &clear);

After burnt this example, PC serial terminal will print original value RGBC(red, green, blue, clear).
