SPIOut
======

SPIOut node is used for **sending data to a MCU** (via SPI).
You can find demos `here <https://github.com/luxonis/esp32-spi-message-demo>`__.

:ref:`SPIIn` is used for receiving data from the MCU (via SPI).

How to place it
###############

.. tabs::

  .. code-tab:: py

    pipeline = dai.Pipeline()
    spi = pipeline.create(dai.node.SPIOut)

  .. code-tab:: c++

    dai::Pipeline pipeline;
    auto spi = pipeline.create<dai::node::SPIOut>();


Inputs and Outputs

- :code:`input` - :code:`Any`

Usage
#####

.. tabs::

  .. code-tab:: py

    pipeline = dai.Pipeline()
    spi = pipeline.create(dai.node.SPIOut)

    spi.setStreamName("spimetaout")
    spi.setBusId(0)

  .. code-tab:: c++

    dai::Pipeline pipeline;
    auto spi = pipeline.create<dai::node::SPIOut>();

    spi->setStreamName("spimetaout");
    spi->setBusId(0);
