Dependencies:   WIZnetInterface SDFileSystem httpServer mbed-src

Fork of TCPEchoServer-WIZwiki-W7500 by WIZnet

This is HTTP server example program for WIZwiki-W7500.

In this example, only you can control RGB LED on/off.

Sample html pages and image are needed. So download samples.

  • index.html
  • dio_page.html
  • image
