WIZnet / Mbed 2 deprecated WizFi310_Legacy_Ubidots

Ubidots example for WizFi310

Dependencies:   WizFi310Interface_Legacy mbed

Fork of WizFi310_Ubidots by WIZnet

Prerequisite

This example is for sending data to Ubidots(Server).

WIZwiki-W7500 and WizFi310 Shield act as TCP client mode.

To implement this function, you need a Platform board and Wi-Fi board. Below are what we used.

  • WIZwiki-W7500 from WIZnet (Platform board)
  • WizFi310 from WIZnet (Wi-Fi board)
  • ETC: PGM5537(CDS sensor) + 10k resistor

Hardware Configuration

WIZwiki-W7500 Pin map

pin map

  • D0 is for RXD, D1 is for TXD
  • D6 is for CTS, D7 is for RTS
  • D9 is for RESET

WizFi310 Pin map

pin map

  • J1 is for RXD, J3 is for TXD
  • SW6-1 is connected to D6 for RTS, SW6-2 is connected to D7 for CTS
  • SW5-3 is connected to D9 for RESET

Caution

This example requires "Variable ID" and "TOKEN value" that can be obtained by signning up to the Ubidots. //
