How do i manually add file C and file H ??

[Andrew Neil]

You haven't said what IDE you're using but, for STM32CubeIDE:

1. copy the .c file into a folder in your project which already has source files;
2. copy the .h file into a folder in your project which already has header files.

(depending on how your project is set up, those could be the same folder)

I am using STM32CubeIDE. need to add in Core>Inc and Core> Src  ???

Lwip Should be enabled or disabled??

Sorry for so many questions, as I am just starting to work with stm32 controllers and practicing

Ethernet is really not a beginner's project - you should probably start with some more basic projects to get familiar with the tools...

EDIT:

You also haven't said what STM32 you're using, what hardware, etc.

Again, please see the Posting Tips:

PS:

Try a search in the Knowledge Base; eg,

https://community.st.com/t5/stm32-mcus/how-to-use-the-lwip-ethernet-middleware-on-the-stm32h5-series/ta-p/691100?search-action-id=38526787183&search-result-uid=691100

Also, as previously noted, LwIP is a widely-used independent 3rd-party project - so a general web search should find a lot...

Is that a commercial board, or your own custom design?
