.. _module-pw_sys_io_arduino:
-----------------
pw_sys_io_arduino
-----------------
``pw_sys_io_arduino`` implements the ``pw_sys_io`` facade over
`Arduino's Serial interface <https://www.arduino.cc/reference/en/language/functions/communication/serial/>`_.
On initialization it runs Arduino's first ``Serial`` interface at a 115200 baud
rate:
.. code-block:: cpp
Serial.begin(115200);
// Wait for serial port to be available
while (!Serial) {}
After ``Serial.begin(115200)`` it will busy wait until a host connects to the
serial port.
.. seealso::
- :ref:`target-arduino` target documentation for a list of working hardware.
- :ref:`module-pw_arduino_build` for caveats when running Pigweed on top of
the Arduino API.
