CircuitPython driver for OV2640 Camera.
This driver is designed to work directly with the OV2640 camera module through an 18-pin header.
It does not work with products such as ArduCam which process the camera data themselves.
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>`_.
* `ESP32-S2 Kaluga Dev Kit featuring ESP32-S2 WROVER <https://www.adafruit.com/product/4729>`_
Usage Example
=============
Using the ESP32-S2 Kaluga Dev Kit and its included camera, capture a 160x120 image into a buffer:
.. code-block:: python3
import board
from adafruit_ov2640 import OV2640, OV2640_SIZE_QQVGA
bus = busio.I2C(scl=board.CAMERA_SIOC, sda=board.CAMERA_SIOD)
cam = OV2640(
bus,
data_pins=board.CAMERA_DATA,
clock=board.CAMERA_PCLK,
vsync=board.CAMERA_VSYNC,
href=board.CAMERA_HREF,
mclk=board.CAMERA_XCLK,
size=OV2640_SIZE_QQVGA,
)
buf = bytearray(2 * cam.width * cam.height)
cam.capture(buf)
Documentation
=============
API documentation for this library can be found on `Read the Docs <https://docs.circuitpython.org/projects/ov2640/en/latest/>`_.
