Configuring SPI Communication on ESP32 for Transmitting Images from OV2640 Camera Module

in continuation with my project Object Detection with MicroPython and OV2640 Camera Module Using ESP-WROOM-32. How do i configure SPI communication on the ESP32 for transmitting images captured by the OV2640 camera?
Solution
@Enthernet Code for transmitting images captured by the OV2640, you'll want to set up the camera to capture images in a format that can be efficiently transmitted over SPI. the OV2640 can output images in JPEG format, which is compressed and more manageable in size, after capturing an image, you can send it over 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)

Remember, you'll need to implement or use an existing library to interface with the OV2640 in MicroPython. This will handle image capture and any necessary configuration of the camera module.
