scheduler API to achieve the same (``scheduler.yield(duration=0)``)

list the serial devices attached to my Linux/Windows system?
|

------------------------------------------------------------
|

|
||||
You can do it by running::
|
||||
|
||||
$ python3 -m serial.tools.list_ports -v
|
||||
|
||||
It will give you the ``/dev/ttyUSBxx`` (or the ``COMxx`` for Windows) device
|
||||
names.
|
||||
The ``hwid:`` field gives you the string you can pass via the ``hwgrep://``
|
||||
feature of pyserial
|
||||
`serial_for_url() <http://pyserial.sourceforge.net/pyserial_api.html#serial.serial_for_url>`_
|
||||
in order to open a serial device.
|
||||
|
||||
See the :ref:`TDC001 documentation <tdc001-controller-usage-example>` for an example of ``hwgrep://`` usage.
