OV2640

OV2640

, you'll want to set up the camera to capture images in a format that can be efficiently transmitted over

SPI

SPI

. the

OV2640

OV2640

can output images in

JPEG

JPEG

format, which is compressed and more manageable in size, after capturing an image, you can send it over

SPI

SPI

using something like this:

def send_image(image_data):
    cs.value(0)  # Select the SPI device
    spi.write(image_data)  # Transmit the image data
    cs.value(1)  # Deselect the SPI device

image_data = capture_image()

send_image(image_data)

def send_image(image_data):
    cs.value(0)  # Select the SPI device
    spi.write(image_data)  # Transmit the image data
    cs.value(1)  # Deselect the SPI device

image_data = capture_image()

send_image(image_data)

Remember, you'll need to implement or use an existing library to interface with the

OV2640

MicroPython

MicroPython

. This will handle image capture and any necessary configuration of the camera module.
