Tomasz Bursztyka e18fcbba5a device: Const-ify all device driver instance pointers Now that device_api attribute is unmodified at runtime, as well as all the other attributes, it is possible to switch all device driver instance to be constant. A coccinelle rule is used for this: @r_const_dev_1 disable optional_qualifier @ @@ -struct device * +const struct device * @r_const_dev_2 disable optional_qualifier @ @@ -struct device * const +const struct device * Fixes #27399 Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>		2020-09-02 13:48:13 +02:00

.. _vl53l0x:

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.
