VL53L0X: Time Of Flight sensor
##############################

Overview
********
This sample periodically measures distance between vl53l0x sensor
and target. The result is displayed on the console.
It also shows how we can use the vl53l0x as a proximity sensor.


Requirements
************

This sample uses the VL53L0X sensor controlled using the I2C interface.

Building and Running
********************

 This project outputs sensor data to the console. It requires a VL53L0X
 sensor, which is present on the disco_l475_iot1 board.

 .. code-block:: console

    $ cd samples/sensors/vl53l0x
    $ mkdir disco_l475_iot1 && cd disco_l475_iot1
    $ cmake -DBOARD=disco_l475_iot1 ..
    $ make

Sample Output
=============

 .. code-block:: console

    prox is 0
    distance is 1938
    prox is 1
    distance is 70
    prox is 0
    distance is 1995
