+VL6180
+######
+
+Origin:
+   ST Microelectronics
+   https://www.st.com/en/embedded-software/stsw-img011.html
+
+Status:
+   version 1.4.0
+
+Purpose:
+   ST Microelectonics official API to use vl6180 sensor.
+
+Description:
+   This library written by STMicroelectronics is dedicated to vl6180 time of flight sensor.
+   Instead of providing a full description of the registers, ST decided to provide a C library to drive this sensor.
+
+   This library is called from the vl6180 driver and is kept transparent for user.
+   User is calling a standard Zephyr driver and then, the driver makes some calls to this library.
+
+   In order to fit with Zephyr rules and simplify version updates, we have done a minimum of modifications :
+      - keep only API directory
+        (remove documentation and samples, see ST website for this)
+      - rename Api to api
+      - customize api/platform to fit in Zephyr (mainly for I2C access)
+        vl53l0x_platform.c has been moved to Zephyr drivers directory.
+
+   In order to use this library, you have to :
+      * define CONFIG_HAS_STLIB and CONFIG_VL53L0X
+      * use 1 in prj.conf (needed for abs function)
+      * include vl53l0x_api.h and vl53l0x_platform.h in the driver .h
+
+Dependencies:
+   This package depends on Zephyr I2C implementation and is linked statically.
+   This library will be used by a standard Zephyr driver.
