How to Properly Connect and Initialize OV2640 Camera Module with ESP-WROOM-32 Using MicroPython?

hello guys, am workin on an Object Detection with MicroPython and OV2640 Camera Module Using ESP-WROOM-32 what is the most proper and efficient way to setup the hardware connection between the OV2640 and ESP-WROOM-32 , i have also writing a basic script in MicroPython to capture an image using the OV2640 camera module on ESP32 but getting the error failed to initialize camera, here is my code: Install necessary MicroPython libraries:

   import machine
   import esp32
   import camera

   def init_camera():
       camera.init(0, d0=24, d1=35, d2=32, d3=5, d4=39, d5=36, d6=19, d7=21, xclk=4, pclk=18, vsync=25, href=23, siod=26, sioc=27)
   init_camera()

   import machine
   import esp32
   import camera

   def init_camera():
       camera.init(0, d0=24, d1=35, d2=32, d3=5, d4=39, d5=36, d6=19, d7=21, xclk=4, pclk=18, vsync=25, href=23, siod=26, sioc=27)
   init_camera()

Interfacing ESP32-WROOM-32 16M with OV2640 camera

Hello everyone, I'm experiencing an issue with a custom PCB designed for the ESP32-WROOM-32 module, mimicking the ESP32-CAM AI-Thinker design, specifically regarding camera initialization. Quick facts: ESP32-WROOM-32 with camera connections identical to AI-Thinker ESP32-CAM. Camera Module: OV2640 (as in original AI-Thinker design). Camera fa...
