OV5640 not detected

[GoostYTQC]

Startup Failure: Camera init error 0xffffffff on CAMERA_MODEL_AI_THINKER i try whit the default example and it work correctly but with this code i just throw me a error

[davemaster]

Turn the power off, and carefully, using lens, check if you plugged the camera correctly, check the flex... take a picture

i just try white esp32-cam-webserver and it work so something in the code does detect the camera correctly, or i need to change something in the code ?

[davemaster]

What ESP32 based camera have You got? You have to change the code according the module you are going to use... picture (complete) of your camera module pls.

i used this code to make sure it get the right id and it output Sensor PID: 0x5640

That camera module, is not the one included with the ESP32-CAM, have You confirm it is compatible?

I just run the code, without problems, assure You change the camera to

I used Arduino IDE to compile the code... I'm very busy now, but tomorrow I will test it in my own ESP32-CAM module

like i said i try with 2 different code, the official one and esp32-cam-webserver they both detect the modul as 5640 and output a video so my guest its something wrong with this code. oh btw the screenshot you show its not even for this code, the one on the screenshot it the official one from the esp32 lib

YES!!!!! I FIX IT

Sensor PID: 0x5640 Camera Model: [00:00:01.915 prepCam] Camera init OK for model OV5640 on board CAMERA_MODEL_AI_THINKER

i had to change : #define FB_CNT 4 // number of frame buffers in the file mjpeg2sd to #define FB_CNT 2 // number of frame buffers

Camera issue, don't forget a picture (better a video) of your success
