julientiron 0:84fb42fedc5b 8 * The VL6180x by ST micro is a time of flight range finder that
julientiron 0:84fb42fedc5b 9 * uses pulsed IR light to determine distances from object at close
julientiron 0:84fb42fedc5b 10 * range. The average range of a sensor is between 0-200mm
julientiron 0:84fb42fedc5b 11 *
julientiron 0:84fb42fedc5b 12 * In this file are the function prototypes in the VL6180x class
julientiron 0:84fb42fedc5b 13 *
julientiron 0:84fb42fedc5b 14 * Resources:
julientiron 0:84fb42fedc5b 15 * This library uses the Arduino Wire.h to complete I2C transactions.
julientiron 0:84fb42fedc5b 16 *
julientiron 0:84fb42fedc5b 17 * Development environment specifics:
julientiron 0:84fb42fedc5b 18 * IDE: Arduino 1.0.5
julientiron 0:84fb42fedc5b 19 * Hardware Platform: Arduino Pro 3.3V/8MHz
julientiron 0:84fb42fedc5b 20 * VL6180x Breakout Version: 1.0
julientiron 0:84fb42fedc5b 21 *
julientiron 0:84fb42fedc5b 22 * Some settings and initial values come from code written by Kris Winer
