You can find an example for the onboard Ethernet controller in the compiler examples, in the following location:
..\Examples\Development Systems\EasyPIC Fusion v7\Ethernet Demo\
In that demo example, you can see a web page, which is used to control the circles on the TFT (turn off and on "virtual LEDs"), and vice versa - you can check their status on that web page, if you touch the circles, turning them off or on.
You need to set up some things first, according to your network - arrays like myIP, gwIpAddr, dnsIpAddr and ipMask, have to be set, to comply with your network settings. After compiling, you need to point your browser to the myIP address and the page will open, if all has been set correctly.
