hudakz 0:68a0003c4cb8 1 /* In this example LED1 is switched on/off using a web browser connected to this HTTP server.
hudakz 4:d34811deedab 2 * The example is based on the Tuxgraphics Web Switch <http://www.tuxgraphics.org/>.
hudakz 4:d34811deedab 3 * This HTTP server is built around the the ENC28J60 chip
hudakz 4:d34811deedab 4 * driven by the UIPEthernet library <https://github.com/ntruchsess/arduino_uip>
hudakz 0:68a0003c4cb8 5 * ported to mbed.
