charlesmn 0:2ee129a3b1e8 2 * This VL53L1 test application performs range measurements
charlesmn 0:2ee129a3b1e8 3 * using the onboard embedded centre sensor and two satelites, in ranging, interrupt mode.
charlesmn 0:2ee129a3b1e8 4 * This program does not use the expansion board and the sensors a directly connected to the F401.
charlesmn 0:2ee129a3b1e8 5 * Measured ranges are ouput on the Serial Port, running at 115200 baud.
charlesmn 0:2ee129a3b1e8 6 *
charlesmn 0:2ee129a3b1e8 7 * This is designed to work with MBed V2 , MBed V5 and MBed V6.
charlesmn 0:2ee129a3b1e8 8 *
charlesmn 0:2ee129a3b1e8 9 *
charlesmn 0:2ee129a3b1e8 10 * The Reset button can be used to restart the program.
