STM32H7 lwip web server

Hello,

I need to implement a web server on STM32H7 using lwip.

I have managed to implement it using online tutorials from youtube. However, I do not understand how it works. I need to modify the example from internet.

Does anyone have any source that can help me understand how the implementation of lwip web server works?

Thank you in advance, and sorry if my question is not so relevant.

Best regards,

Vouria
