The repository is always a very good source of sample programs. BTW: There's a reason the different STM32 families have so large firmware packages - beside the pure drivers and BSP there are also a huge number of examples for almost all kits from STMicroelectronics.
So if you e.g. want to use LwIP on a NUCLEO-F207ZG just:
- open your repository STM32Cube_FW_F2 and
- navigate to Projects\NUCLEO-F207ZG\Applications\LwIP\LwIP_HTTP_Server_Netconn_RTOS and
- import the project from folder SW4STM32
Additional hint: copy the folder LwIP_HTTP_Server_Netconn_RTOS to e.g. LwIP_HTTP_Server_Netconn_RTOS_ORI, because that opens up the possibility of comparing both folders later to find differences or maybe restore things you've maybe deleted.
Good luck!
