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

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
