如何在 ESP32 中为 OV7670 摄像头模块编写 MicroPython 代码

Question

我想用micro python为ov7670相机模块编写代码，但我找不到它的代码，我只找到了C代码，但我想编写micro python代码，请帮我写一个代码。
我找到了这个代码，我该如何使用它？？？？

import time
import uos
from machine import Pin, UART

# Define pins
OV7670_RST_PIN = 17
OV7670_PWDN_PIN = 16
OV7670_XCLK_PIN = 6
OV7670_PCLK_PIN = 8
OV7670_VSYNC_PIN = 7
OV7670_DATA_PIN = 0

# Define camera parameters
OV7670_IMG_WIDTH = 160
OV7670_IMG_HEIGHT = 120

# Initialize camera
uart = UART(0, baudrate=1000000, tx=Pin(OV7670_XCLK_PIN, Pin.OUT))

# Reset camera
Pin(OV7670_RST_PIN, Pin.OUT).value(0)
Pin(OV7670_PWDN_PIN, Pin.OUT).value(1)
time.sleep_ms(10)
Pin(OV7670_RST_PIN, Pin.OUT).value(1)
time.sleep_ms(10)

# Wait for camera to initialize
while not uos.stat('/dev/uart/0'):
    time.sleep_ms(10)

# Configure camera
uart.write(b'\x56\x00\x26\x00')
uart.write(b'\x56\x00\x36\x1')
uart.write(b'\x56\x00\x3a\x01\x0a')
uart.write(b'\x56\x00\x11\x01')
uart.write(b'\x56\x00\x3c\x10')

# Capture image
img_data = b''
while len(img_data) != OV7670_IMG_WIDTH * OV7670_IMG_HEIGHT * 2:
    while Pin(OV7670_VSYNC_PIN, Pin.IN).value() == 1:
        pass
    while Pin(OV7670_VSYNC_PIN, Pin.IN).value() == 0:
        pass
    for i in range(OV7670_IMG_WIDTH * 2):
        img_data += bytes([uart.read(1)[0]])

# Process image data
# TODO: Perform further processing on the image data as needed

# Clean up
uart.write(b'\x56\x00\x11\x00')

现在有一个用于 ESP32 的模块，可以与 OV7670 和 OV2640 相机进行通信。请参阅https://github.com/cnadler86/mp_camera/
