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:

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>.

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)
