WIZnet
Dweet IO example with "Wiznet W5500 Ethernet kit for IoT".
Dependencies: HTTPClient WIZnet_Library mbed WIZnetInterface
1. WIZwiki-W7500
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
WIZwiki-W7500 Pin map

2. W5500 Ethernet Kit
- Platform: LPCXpresso11U68
- Component: W5500 Ethernet kit for IoT.
- ETC: PGM5537 + 10k resistor
now, I can send data to dweet.io & freeboard.io but so simple ;).
