Zoltan Hudak / Mbed 2 deprecated WebSwitch_WIZ550io

HTTP Server serving a simple webpage which enables to remotely turn LED1 on/off. Compile, download, run and type 'IP_address/secret/' (don't forget the last '/') into your web browser and hit ENTER.

Dependencies: W5500Interface mbed

Turn LED1, or other digital output, on/off using a web browser.

In this example we create a HTTP server that will serve a simple Web page to remotely turn LED1, or other digital output on the mbed board, on/off by using a web browser. A WIZ550io module or W5500 Network-Shielld is used to assure connection between the mbed module and the Ethernet network (Internet).

Needed parts:

mbed board
WIZ550io module or W5500 Network-Shield
Wires
Web browser (Internet Explorer, Safari, Firefox, Chrome ...) running on Windows, Mac, Linux, iPhone or Android device.

The project was inspired by the Tuxgraphics Web Switch. Thank you Guido!

NOTE:

For a Web Switch using an ENC28J60 Ethernet module see WebSwitch_ENC28J60
For a Web Switch using mbed's built in Ethernet PHY see WebSwitch_mbed-dev or WebSwitch_mbed-os

hudakz	3:d0e3d1bd73e6	2	* In this example LED1 on the mbed board is turned on/off using a web browser.
hudakz	1:343d3c7e13b8	3	* However, you can easily modify the project to remotely switch on/off any external device.
hudakz	0:5c8e08cf3b33	4	* The HTTP server is built from an mbed board and a WIZ550io board.
hudakz	0:5c8e08cf3b33	5	* The example is based on the Tuxgraphics Web Switch <http://www.tuxgraphics.org/>.
hudakz	5:458d9d7b5c1b	6	* For more details see <https://developer.mbed.org/users/hudakz/code/WebSwitch_WIZ550io/wiki/Homepage>
hudakz	4:31010e482971	7	* Thanks to Jozsef Voros it works now also with the W5500 modules without a built-in MAC
hudakz	3:d0e3d1bd73e6	8	* See below how to enable that.
