:name: STWIN.box sensors
|
|
|
|
Read sensor data from the various STWIN SensorTile wireless industrial node sensors.
|
|
|
|
Overview
|
|
********
|
|
This sample provides an example of how to read sensors data
|
|
from the STWIN.box board.
|
|
|
|
This sample enables all sensors of STWIN.box board, and then
|
|
periodically reads and displays data on the console from the following
|
|
sensors:
|
|
|
|
- STTS22H: Digital temperature sensor
|
|
- IIS2MDC: 3-axis magnetometer
|
|
- ISM330DHCX: IMU, 3D accelerometer and 3D gyroscope with Machine Learning Core and Finite State Machine
|
|
- IIS2DLPC: high-performance ultra-low-power 3-axis accelerometer for industrial applications
|
|
- IIS2ICLX: high-accuracy, high-resolution, low-power, 2-axis digital inclinometer with Machine Learning Core
|
|
- ILPS22QS: ultra-compact piezoresistive absolute pressure sensor
|
|
|
|
Requirements
|
|
************
|
|
|
|
The application requires a STWIN.box board connected to the PC
|
|
through USB. The board shows up as a USB CDC class standard device.

Building and Running
|
|
********************
|
|
|
|
Build and flash the sample in the following way:
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/boards/st/steval_stwinbx1/sensors
|
|
:board: steval_stwinbx1
|
|
:goals: build flash
|
|
|
|
Please note that flashing the board requires a few preliminary steps described
|
|
in :ref:`steval_stwinbx1_board`.
|
|
|
|
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 correct device path automatically created on
|
|
the host after the STWIN.box board gets connected to it,
|
|
usually :code:`/dev/ttyUSBx` or :code:`/dev/ttyACMx` (with x being 0, 1, 2, ...).
|
|
The ``-b`` option sets baud rate ignoring the value from config.
|
|
|
|
Sample Output
