Prerequisite

This example shows that WIZwiki-W7500 and WizFi310 connects to AP.

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)

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

Software

Connect to Wi-Fi

main.cpp

if ( wizfi310.connect(SECURE, SSID, PASS))      return -1;

Caution

Input a SSID/PW to connect to an AP.
