cliff Hong / Mbed 2 deprecated dweetIoExample

Dweet IO example for WIZwiki-W7500

Dependencies:   HTTPClient WIZnetInterface mbed

Fork of dweetIoExample by WIZnet

Prerequisite

This example is for sending data to DweetIO.

To implement this function, you need a Platform board, network Interface board.

  • WIZwiki-W7500 from WIZnet (Platform board and Ethernet I/F board)
  • ETC: PGM5537(CDS sensor) + 10k resistor

Hardware Configuration
