good evening I have a problem with an esp32 cam. the cam is an ov2640 module and the esp32-s but I can’t see anything if it hasn’t commanded the led. Does anyone have this cam module and can you give me an example of code?
Thank
i have tried all the sample templates but none work
You don’t give much any information about which module that could be 
So you are aware that there is a lot of different modules 
Maybe start reading here 
And then try to ask a good question with as much useful information you can deliver 
mine was just a question, I know very well that it is not a help desk. I have tried all the examples but none work I can only control the flash I have looked at there are many cam modules and all of the examples are different from mine. now I have ordered other modules when they arrive I do other tests. Thank you
Hi ,
I have the ov2640 Module in Use.

.Hope, this is helpfull for you
We don’t even know which specific board or YAML you are using. Do you expect us to mind-read you?
Help us help you.
You can post the ESPHome logs. Also check that the camera cable is properly inserted into the module.
Hi, thanks for your reply.
I did not expect an answer.
I only wanted to answer to the inital post of Roberto, where a valid configuration for cam modul ov2640 was asked for.
On my side this module works with the esp home yaml file I have posted.
