Fork of WiFiDip-UsbKitchenSink by Carl - SolderSplash Labs

http://www.soldersplash.co.uk/products/wifi-dipcortex/

Demo shows you how to implement the CC3000 library with the WiFi DipCortex.

The demo shows :

  • USB CDC ( Serial ) Menu system allow control of the module and starting each example
  • Smart Connect
  • Manual connect
  • Connection status
  • Ping
  • TCP Client
  • TCP Server
  • Web Socket read/write to sockets.mbed.org
  • HTTP Client test Post, Put, Delete
  • Posting ADC data to Xively every 1 second
  • UDP Client
  • UDP Server
  • NTP Example, contacts time server to get the current time

You will need a Driver for the USB CDC port which can be found here : http://www.soldersplash.co.uk/docs/DipCortex-USB-CDC.zip

Please refer to : http://mbed.org/users/SolderSplashLabs/notebook/dipcortex---getting-started-with-mbed/ as well as the SolderSplash Forum for support http://forum.soldersplash.co.uk/viewforum.php?f=15
