/******************************************************************************
 * Developed from
 * VL6180X_demo.ino
 * Example Sketch for VL6180x time of flight range finder.
 * Casey Kuhns @ SparkFun Electronics
 * 10/29/2014
 * https://github.com/sparkfun/ToF_Range_Finder-VL6180_Library
 * 
 * The VL6180x by ST micro is a time of flight range finder that
 * uses pulsed IR light to determine distances from object at close
 * range.  The average range of a sensor is between 0-200mm
 * 
 * Resources:
 * This library uses the Arduino Wire.h to complete I2C transactions.
 * 
 * Development environment specifics:
 *  IDE: Arduino 1.0.5
 *  Hardware Platform: Arduino Pro 3.3V/8MHz
 *  VL6180x Breakout Version: 1.0
 * 
 * 
 * This code is beerware. If you see me (or any other SparkFun employee) at the
 * local pub, and you've found our code helpful, please buy us a round!
 * 
 * Distributed as-is; no warranty is given.
