FOURNET Olivier / Mbed 2 deprecated Nucleo_Web_ENC28J60

HTTP server is created by connecting an ENC28J60 module to the mbed board. It is serving a webpage which enables remotely turn on/off LED1 (or other device). Compile, download, run and type 192.168.0.170/secret/ into your web browser and Flot Interactivity Graphique

Dependencies:   UIPEthernet mbed FCT_WEB hebergement

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.
