Introduction

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
• Bus Device

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle or individual libraries can be installed using circup.

• ESP32-S2 Kaluga Dev Kit featuring ESP32-S2 WROVER

Usage Example

Using the ESP32-S2 Kaluga Dev Kit and its included camera, capture a 160x120 image into a buffer:

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)
