APDS 9960 gesture sensor

Projects Programming
1

I am using APDS-9960 Gesture sensor with arduino DUE using SparkFun library but it does not seems to work.

I guess I do not need any logic converter here between sensor and due because DUE operates on 3.3V so does the gesture sensor.

This is the sensor I am using "RGB and Gesture Sensor - APDS-9960 - Proximity Detection Sensor Module"

Below is the code I am using.

#include<Wire.h>
#include<SparkFun_APDS9960.h>
#define gesture_interrupt 2

SparkFun_APDS9960 apds9960 = SparkFun_APDS9960();

volatile int interrupt_flag = 0;

void setup() 
{
 pinMode(gesture_interrupt, INPUT);
 Serial.begin(9600);

  attachInterrupt(0, interruptRoutine, FALLING);

  if(apds9960.init())
  {
    Serial.println("FOUND APDS-9960 Module!");
  }
  else
  {
    Serial.println("Can't find APDS-9960 MODULE");
  }

  if ( apds9960.enableGestureSensor(true)) 
  {
    Serial.println("Gesture sensor is enabled!");
  } 
  else 
  {
    Serial.println("Can't start the Gesture sensor...");
  }
}

void loop() 
{
  if(interrupt_flag == 1)
  {
    detachInterrupt(0);
    handleGesture();
    interrupt_flag = 0;
    attachInterrupt(0, interruptRoutine, FALLING);
  }
}

void interruptRoutine()
{
  interrupt_flag = 1;
}

void handleGesture()
{
  if(apds9960.isGestureAvailable())
  {
    switch(apds9960.readGesture())
    {
      case DIR_UP:
      Serial.println("UP");
      delay(500);
      break;
      
      case DIR_DOWN:
      Serial.println("DOWN");
      delay(500);
      break;

      case DIR_LEFT:
      Serial.println("LEFT");
      delay(500);
      break;

      case DIR_RIGHT:
      Serial.println("RIGHT");
      delay(500);
      break;

      case DIR_NEAR:
      Serial.println("NEAR");
      delay(500);
      break;

      case DIR_FAR:
      Serial.println("FAR");
      delay(500);
      break;
    }
  }
}

SDA pin 20
SCL pin 21
interrupt pin 2

VCC 3.3V and GND from DUE board

Let me know if I am missing anything in the code or in the connection?

Thanks in advance.

  attachInterrupt(0, interruptRoutine, FALLING);

Interrupt 0 being on pin 2 works only on ATmega328 or ATmega2560 based Arduinos. Use digitalPinToInterrupt() to translate, this should work on all supported platforms:

  attachInterrupt(digitalPinToInterrupt(2), interruptRoutine, FALLING);
