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
