Arduino Due and Adafruit TCS34725

At first I had this error

:15:43: error: 'TCS34725_INTEGRATIONTIME_700MS' was not declared in this scope
Adafruit_TCS34725 tcs = Adafruit_TCS34725(TCS34725_INTEGRATIONTIME_700MS, TCS34725_GAIN_1X);
Compilation error: Error: 2 UNKNOWN: exit status 1

so I swapped to 154MS. I can compile and upload the code, but it won't recognize the device via serial monitor

#include <Wire.h>
#include "Adafruit_TCS34725.h"
/* Example code for the Adafruit TCS34725 breakout library */
/* Connect SCL to analog 5
Connect SDA to analog 4
Connect VDD to 3.3V DC
Connect GROUND to common ground */
/* Initialise with default values (int time = 2.4ms, gain = 1x) */
// Adafruit_TCS34725 tcs = Adafruit_TCS34725();
/* Initialise with specific int time and gain values */
Adafruit_TCS34725 tcs = Adafruit_TCS34725(TCS34725_INTEGRATIONTIME_154MS, TCS34725_GAIN_1X);
void setup(void) {
if (tcs.begin()) {
Serial.println("Found sensor");
} else {
Serial.println("No TCS34725 found ... check your connections");
while (1);
// Now we're ready to get readings!
void loop(void) {
uint16_t r, g, b, c, colorTemp, lux;
tcs.getRawData(&r, &g, &b, &c);
colorTemp = tcs.calculateColorTemperature(r, g, b);
lux = tcs.calculateLux(r, g, b);
Serial.print("Color Temp: "); Serial.print(colorTemp, DEC); Serial.print(" K - ");
Serial.print("Lux: "); Serial.print(lux, DEC); Serial.print(" - ");
Serial.print("R: "); Serial.print(r, DEC); Serial.print(" ");
Serial.print("G: "); Serial.print(g, DEC); Serial.print(" ");
Serial.print("B: "); Serial.print(b, DEC); Serial.print(" ");
Serial.print("C: "); Serial.print(c, DEC); Serial.print(" ");
Serial.println(" ");

No TCS34725 found ... check your connections

Adafruit TCS34725 library is installed

SCL to analog 5
SDA to analog 4
VDD to 3.3V DC
GROUND to common ground


connected to PIN20/21 SDA/SCL
