There is no gpio in lwIP
"gpio" means General Purpose Input Output and is a common name for the
I/O ports in some processors. It is a processor thing.
lwIP does not talk to gpios, lwIP is a TCP/IP stack, you write
applications that do what you want them to do, and if that is moving I/O
pins (or "talk to gpios") then you will write the code that does that.
You need a web server  and have to write the equivalent to a CGI script
or use SSI. The HTML on the hosted page may read an internal variable
(SSI) or call a function (CGI) which does the trick.
Besides that, you are better off asking for guidance on your processor

And please, don't crosspost and don't send user questions to developer's
