geiineuville 0:441400ffd086 3 // Example of HTTPServer with additional features:
geiineuville 0:441400ffd086 4 // * SNTP Client (Simple NTP)
geiineuville 0:441400ffd086 5 // * Link status indication (LED4 or RJ45 socket LED on MBED-BoB2-mod)
geiineuville 0:441400ffd086 6 // * Local file system (create index.htm page on MBED!)
geiineuville 0:441400ffd086 7 // * SD-based WebServer
geiineuville 0:441400ffd086 8 // * ////RPC-able class (myrpc, allows remote function call that blinks LED1 N times)
geiineuville 0:441400ffd086 9 // * Static HTML page
geiineuville 0:441400ffd086 10 // * Dynamic HTML page
geiineuville 0:441400ffd086 11 // modification fron LRSD from the pub-iva2k-ethsntp project

geiineuville 0:441400ffd086 14 // 2 Plug ETH connector into your network(with a switch for direct pc, needs DHCP to get IP address and Internet connection)
geiineuville 0:441400ffd086 15 // 3 Plug MBED using USB cable
geiineuville 0:441400ffd086 16 // 4 need to have Installed MBED serial driver (http://mbed.org/handbook/SerialPC)
geiineuville 0:441400ffd086 17 // 5 Copy compiled .bin to your MBED (make sure target device selected in the compiler is correct)
geiineuville 0:441400ffd086 18 // 6 Open terminal on the mbed serial port
geiineuville 0:441400ffd086 19 // 7 Push MBED reset button
