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

ST SensorTile.box
#################

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.
