TCP Client, WIZwiki-W7500ECO. It will get weather of South Korea from openweathermap.org
Dependencies: WIZnetInterface mbed
Fork of TCPClient_HelloWorld by
Prerequisite
This example is for obtainning and printting data from server(OpenWeatherMap). WIZwiki-W7500ECO is TCP client mode.
To implement this function, you need a Platform board, network Interface board.
- WIZwiki-W7500ECO from WIZnet (Platform board and Ethernet I/F board) http://wizwiki.net/wiki/doku.php?id=products:wizwiki-w7500eco:start
Hardware Configuration
WIZwiki-W7500ECO Pin map
Software
