Gerard Marull-Paretas 93b63df762 samples, tests: convert string-based twister lists to YAML lists
Twister now supports using YAML lists for all fields that were written
as space-separated lists. Used twister_to_list.py script. Some artifacts
on string length are due to how ruamel dumps content.

Overview
********
This sample provides an example of how to read sensors data
from the SensorTile.box board.

This sample enables all sensors of SensorTile.box board, and then
periodically reads and displays data on the console from the following
sensors:

- HTS221: ambient temperature and relative humidity
- LPS22HH: ambient temperature and atmospheric pressure
- LIS2DW12: 3-Axis acceleration
- LSM6DSOX: 6-Axis acceleration and angular velocity
- STTS751: temperature sensor

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

The application requires a SensorTile.box board connected to the PC
through USB. The board declares itself as a USB CDC class device.

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

Build and flash the sample in the following way:

.. zephyr-app-commands::
    :zephyr-app: samples/boards/sensortile_box
    :board: sensortile_box
    :goals: build flash

Please note that flashing the board requires a few preliminary steps described
in :ref:`sensortile_box`.

Then, power cycle the board by disconnecting and reconnecting the USB cable.
Run your favorite terminal program to listen for output.

.. code-block:: console

   $ minicom -D <tty_device> -b 115200

Replace :code:`<tty_device>` with the port where the SensorTile.box board
can be found. For example, under Linux, :code:`/dev/ttyUSB0`.
The ``-b`` option sets baud rate ignoring the value from config.

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

The sample code outputs sensors data on the SensorTile.box console.

If you move the board around or put your finger on the temperature
sensor, you will see the accelerometer, gyro, and temperature values change.
