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. |
