johnAlexander 2:f0ec92af4b5f 2 * This VL53L1X Expansion board test application performs range measurements
johnAlexander 2:f0ec92af4b5f 3 * using the onboard embedded centre sensor and two satelites, in autonomous, interrupt mode.
johnAlexander 2:f0ec92af4b5f 4 * Measured ranges are ouput on the Serial Port, running at 115200 baud.
charlesmn 0:020912dfa221 5 *
charlesmn 0:020912dfa221 6 * This is designed to work with MBed V2 , MBed V5 and MBed V6.
charlesmn 0:020912dfa221 7 *
johnAlexander 2:f0ec92af4b5f 8 * The Reset button can be used to restart the program.

johnAlexander 2:f0ec92af4b5f 10 * *** Note :
johnAlexander 2:f0ec92af4b5f 11 * Default Mbed build system settings disable print floating-point support.
johnAlexander 2:f0ec92af4b5f 12 * Offline builds can enable this, again.
