/*
 *  This VL53L3 Expansion board test application performs range measurements
 *  using the onboard embedded centre sensor, in singleshot, polling mode.
 *  Measured ranges are ouput on the Serial Port, running at 9600 baud.
 *
 *  The User Blue button stops the current measurement and entire program,
 *  releasing all resources.
 *
 *  The Reset button can be used to restart the program.
