SoftMultiplexTCS34725

The SoftMultiplexTCS34725 library allows users to interface with multiple TCS34725 RGB sensors using software-based I2C multiplexing. It's designed to work with both digital and analog pins on Arduino platforms.

Features

Software-based I2C multiplexing for TCS34725 RGB sensors.
Support for both digital and analog pins.
Easy-to-use interface for reading raw color data.

Installation

Download the ZIP file from the GitHub repository.
Open the Arduino IDE, go to Sketch -> Include Library -> Add .ZIP Library, and select the downloaded ZIP file.
Include the library in your sketch by going to Sketch -> Include Library -> SoftMultiplexTCS34725.

Usage

Instantiation

Create instances for each TCS34725 sensor, specifying the integration time, gain, SDA pin, and SCL pin:

#define SDA_PIN_A 3
#define SDA_PIN_B 4
#define SCL_PIN 5

SoftMultiplexTCS34725 tcsA = SoftMultiplexTCS34725(
  TCS34725_INTEGRATIONTIME_50MS, TCS34725_GAIN_4X,
  SDA_PIN_A,
  SCL_PIN
);

SoftMultiplexTCS34725 tcsB = SoftMultiplexTCS34725(
  TCS34725_INTEGRATIONTIME_50MS,
  TCS34725_GAIN_4X,
  SDA_PIN_B,
  SCL_PIN
);

Note: the SCL_PIN(clock) pin can be shared by multiple instances.

Initialization

Initialize each sensor using the begin method:

void beginTcs(SoftMultiplexTCS34725& tcs) {
  if (tcs.begin()) {
    Serial.println("Found sensor");
  } else {
    Serial.println("No TCS34725 found ... check your connections");
    while (1); // halt!
  }
}

beginTcs(tcsA);
beginTcs(tcsB);

Reading Data

Read raw color data from each sensor:

uint16_t red, green, blue, clear;

// Read data from sensor A
tcsA.getRawData(&red, &green, &blue, &clear);
// ...

// Read data from sensor B
tcsB.getRawData(&red, &green, &blue, &clear);
// ...
