I have been working on a pan tilt web controller with the ethernet shield. Ive been searching the web and came across something that Dennis Schissler had wrote for the Xport not the WIZnet 1500. I've made some change to work with the wiznet but haven't had much luck getting it to work. I was wondering if some can take a look at the code?
Thanks
Jed
