-/******************************************************************************
- * 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.
