Modded Arduino Library for SparkFun ISL29125 Breakout

RGB Light Sensor Breakout-ISL29125 (SEN-12829)

Modified code for the ISL29125 RGB Light Sensor. Based on ISL29125_Breakout.

I needed to use multiple ISL29125 sensors at once. They use the same address, which is hardwired and cannot be changed. I decided to use the same approach that Fire7 used for the Adafruit TCS34725 Color Sensor.

Using this library, you initialize ISL29125 giving it two pins that are used for software SDA and SCL:

// Declare sensor object
static int SDA = 2;
static int SCL = 3;
ISL29125_SOFT RGB_sensor;
RGB_sensor.init(SDA,SCL);

So, if you want to use multiple sensors, you can just use different pins:

// Declare sensor objects

RGB_sensor_1.init(2,3);
RGB_sensor_2.init(4,5);
RGB_sensor_3.init(6,7);
RGB_sensor_4.init(8,9);

And then read them as usual:

RGB_sensor_1.readRed();
RGB_sensor_2.readRed();
...etc.
