/*
 *  This VL53L1X Expansion board test application performs range measurements
 *  using the onboard embedded centre sensor, in multizone, polling mode.
 *  Measured ranges are ouput on the Serial Port, running at 115200 baud.
 *
 *
 * This is designed to work with MBed V2 ,MBed V5 and MBed V6.
 *
 *
 *  The Reset button can be used to restart the program.
