ESP32-CAM coding error with CameraWebServer

Using Arduino Programming Questions

Hello! I am very new to ESP32 boards so I have started using ESP32-CAM and tried the CameraWebServer example code. I didn't edit anything besides the internet ssid and password and identifying my board, and I have gotten an error message saying:

any help would be greatly appreciated :slight_smile:

Oh boy! Did you start with the egg frying machine? May God bless your steps!

As far as I know the ESP32-CAM has the OV2640. Did you change the camera model?

Specifications:

Try using a tutorial for getting started:

Is this an ESP32-CAM board that you have selected? ... looks like a standard ESP32 board.

Perhaps try the "AI Thinker ESP32-CAM" board.

5

No I definitely picked the AI thinker ESP32-CAM

6

I’m following the random nerd tutorials one and that is why I’m doing the CameraWebServer

7

Do you have a link?

Many tutorials are based on other tutorials. Generally you need to have fulfilled some prerequisite before doing something more advanced. Initially, in the most basic tutorials, libraries are installed and some configurations are performed. It is probably missing some initial part of the tutorial, or a prerequisite is missing.

To upload the code, follow the next steps:

  1. Go to Tools > Board and select AI-Thinker ESP32-CAM.

Did you follow all the steps correctly?

Did you manage to get the other referenced tutorial to work?

I have already added the ai thinker ESP32-CAM and followed all the steps. I have also downloaded later models of it and still get this message. Are you sure there is nothing wrong with the code?
