Dweet IO example for WIZwiki-W7500
Dependencies: HTTPClient WIZnetInterface mbed
Fork of dweetIoExample by
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
