Pin Definitions, ESP32-Applicability, , Image Classification

[MM-112211]

Hello Computer Nerd,
thanks for the Code so far. I used it as part of indrekluuk's image capture tutorial (https://github.com/indrekluuk/LiveOV7670).
It helped me a lot in first setting up the ov7670 on a nano.

Right now im trying to switch to ESP32 (on ESP32S NodeMCU Dev Kit C, https://www.az-delivery.de/products/esp32-dev-kitc-v2-ai-thinker-soldered), and am having difficulties with available tutorials for that.

I first used the following (and only one I could find) tutorial (https://github.com/bitluni/ESP32CameraI2S) and had a pretty abstract issue (posted it here: https://www.esp32.com/viewtopic.php?f=12&t=34415).

Now I'm asking myself if it would be possible to use your and indrekluuk's code for the task and if i might need to redefine pins.
Would it possible and sensible to do so with reasonable efford? I can't seem to find pin definitions in code (I'm a beginner so it's well possible i just didn't realize).

Secondly I am looking for some longer term advice regarding the application I am aiming for.
I would like to do a on-board image classification with TF-lite or similar libraries on the NodeMCU and am wondering, if the read-in can be done by programs like these or if I have to watch out for special factor like memory allocation to save an entire image before passing it to the algorithm. Here any advice or references would be appreceated greatly since I am mostly a beginner.

Thank you for your time, I hope the questions are readable and relevant.
