Test an Adafruit single VL53L0X breakout board using the mbed LPC1768 and print distance measurement to PC
Dependencies: X_NUCLEO_53L0A1 mbed
Fork of
HelloWorld_53L0A1

ST
https://os.mbed.com/users/kbeck8/notebook/alternative-control-for-remote-control-vehicle/ has a more complex example using three LIDAR breakouts for gesture detection on the same I2C bus using the shutdown pin (solves the issue of them having the same I2C address). The driver has support for three, but an AND gate is required unless the driver is changed. DigitalOut pins turn shutdown on/off on each LIDAR.
