I have put together a web server which turns items on an off , photocell etc - works fine
I am now trying to add the ability to see any ip that is currently connected to my server
ON THE SERIAL LCD: i would like to:
I have looked around and cant seem to find a method to display the ip
Help,
Joe
I have looked around and cant seem to find a method to display the ip
First thing you need to do is get the IP address. Once you have it, displaying it is easy.
Have you got the IP address? Have you searched the forum for the thread where how to modify the library to get the ID address was documented?
Why are you shouting?

byte ip[] = { 192,168,1,121 }; // Set your shield's IP address
byte gateway[] = { 192,168,1,1 }; //if you need a gateway IP
byte subnet[] = { 255,255,255,0 }; // Change to your subnet address

I tried adding the get ip code but get - get_ip:5: error: expected constructor, destructor, or type conversion before '.' token
Not sure if it is the code or where i am putting it.

The code you posted goes not have a get_ip() function defined or called. Are we supposed to guess where you put it?
