This project seems to come fromhttps://github.com/Freenove/Freenove_Development_Kit_for_ESP32_S3/tree/main/Sketches/Sketch_03_CameraWebServer Have you considered posting an issue there? The only difference when using OV5640 is athttps://github.com/Freenove/Freenove_Development_Kit_for_ESP32_S3/blob/main/Sketches/Sketch_03_CameraWebServer/camera_index.h#L998 |

Thank you for the suggestion. I’ve tried the steps mentioned, but unfortunately, the issue persists – the OV5640 camera still shows a blank stream. I’ve tested multiple OV5640 cameras and configurations, but the problem remains. I will proceed to post an issue on the Freenove repository as recommended. Appreciate the guidance and support! |

@SaadKhan10000 I tested the camera driver with ov5640 and everything was OK. It must be something on your end that is causing it |

yes, I am using a board with that same module on it. Works as expected. Images, video all. I would guess that maybe some of your pins are not correct or that the sensors are bad or something along these lines. |

Sir@me-no-dev I am using these pins are they correct for my board: #define Y2_GPIO_NUM 11 #define VSYNC_GPIO_NUM 6 OV2640 camera is working good on these pins. |

We have an example here. Maybe try that:https://github.com/espressif/arduino-esp32/tree/master/libraries/ESP32/examples/Camera/CameraWebServer The board you show in the picture above is not ESP32S3-EYE, but maybe it uses the same pins... do not know. Please try our example and see what it says in the serial logs |

@me-no-dev in the example you shared CAMERA_MODEL_ESP_EYE is selected and its pins are different from my board |

You can change in the sketch which pis are used. Comment the ESP_EYE and uncomment the ESP32S3_EYE |

I just bought a OV5640 too and have the same issue. ov2640 works, tried on esp32-cam and esp32-s3 dev using a waveshare module. connects but the data on screen is blank but log shows it is sending something. |

Hi, I connected OV5640 cam to the same board running Tasmota 14.5.0.2 I changed some options to different values, and it seems to me that the values themselves don't significantly increase the brightness, but the change itself makes the image brighter. |

Hi, I'm interested in running that setup with Tasmota - did you compiled it by yourself or used ready binary (which one)? |

I know I am very late to this thread but to those who may visit, I changed my clock frequency from 20000000 to 24000000 and it worked fine. However these cameras are not tested, as stated on the Freenove website. I had issues with overheating with the OV5640s that I bought, but could just be a bad batch. |
