This looks like a compilation or linking problem rather than a crash. Could you copy and paste the text from the error output rather than screenshots? A lot of the text is getting cut off.

Hello, @Meteor !
One thing I’m noticing is that you are using a very outdated version of ESP32 Arduino core - 1.0.6.
In our example files it says

// These sketches are tested with 2.0.4 ESP32 Arduino Core

Can you please test with this particular version?

Meteor · April 26, 2024, 7:53am

when I compiled it with version 2.0.11 a new error appeared :
image_util.h: No such file or directory
Where can i find this library ?

AIWintermuteAI · April 26, 2024, 1:08pm

In our example files it says

// These sketches are tested with 2.0.4 ESP32 Arduino Core

Can you please test with this particular version?

Meteor · April 28, 2024, 7:46am

My arduino ide doesn’t have esp32 2.0.4 version :(((

herbk · April 28, 2024, 11:16am

It is also a very outdatet lib with a lot of known bugs. Current version is 2.0.15. To get it, you may need to change the source to https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

AIWintermuteAI · April 29, 2024, 8:53am

Follow the instructions here to install 2.0.4
https://docs.espressif.com/projects/arduino-esp32/en/latest/installing.html#installing-using-arduino-ide

Meteor · April 29, 2024, 9:14am

I tested it with version 2.0.4 but the same problem :(((
image_util.h: No such file or directory
when I added library image_util.h to my project another problem appeared:
mtmn.h: No such file or directory

You’re trying to compile deprecated example.
Just use the example bundled with the downloaded library.
File → Examples → name of your project → esp32

when I added the required libraries I got the error:

You’re trying to compile deprecated example.
Use the example bundled with the downloaded library.
File → Examples → name of your project → esp32
And build from there.

We cannot provide help debugging deprecated code.
