CircuitPython driver for OV7670 cameras

.. warning::
    This module requires the CircuitPython ``imagecapture`` module which is only in the unreleased development version ("Absolute Newest") of CircuitPython and is only supported on specific boards.

Dependencies
=============
This driver depends on:

* `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_
* `Bus Device <https://github.com/adafruit/Adafruit_CircuitPython_BusDevice>`_

Please ensure all dependencies are available on the CircuitPython filesystem.
This is easily achieved by downloading
`the Adafruit library and driver bundle <https://circuitpython.org/libraries>`_
or individual libraries can be installed using
`circup <https://github.com/adafruit/circup>`_.

.. :: Describe the Adafruit product this library works with. For PCBs, you can also add the image from the assets folder in the PCB's github repo.
.. :: `Purchase one from the Adafruit shop <http://www.adafruit.com/products/>`_



Usage Example
=============

On an Adafruit Metro M4 Grand Central, capture a 40x30 image into a buffer:

.. code-block:: python3

    import board
    from adafruit_ov7670 import OV7670

    cam = OV7670(
        bus,
        data_pins=[board.PCC_D0, board.PCC_D1, board.PCC_D2, board.PCC_D3, board.PCC_D4, board.PCC_D5, board.PCC_D6, board.PCC_D7],
        clock=board.PCC_CLK,
        vsync=board.PCC_DEN1,
        href=board.PCC_DEN2,
        mclk=board.D29,
        shutdown=board.D39,
        reset=board.D38,
    )
    cam.size = OV7670_SIZE_DIV16

    buf = bytearray(2 * cam.width * cam.height)

    cam.capture(buf)
