Sample Output Sample Output
============= =============
To check output of this sample, any serial console program can be used (i.e. on Linux minicom, putty, screen, etc) To check output of this sample, run ``west espressif monitor`` or any other serial console program (i.e. on Linux
This example uses ``picocom`` on the serial port ``/dev/ttyUSB0``: minicom, putty, screen, etc).
This example uses ``west espressif monitor``, which automatically detects the serial port at ``/dev/ttyUSB0``:
.. code-block:: console .. code-block:: console
$ picocom /dev/ttyUSB0 - 115200 $ west espressif monitor
.. code-block:: console .. code-block:: console
