Intro: WIZnet W5500-EVB and Blynk App Communication

Hello! Everyone.

Because app's are being used almost everywhere, I decided to make my own tutorial on how to control my board using App. Some time ago, I found a very interesting app platform, 'Blynk'. But Blynk platform supports only specified devices(like arduino series), so I've porting Blynk library for arduino to my WIZnet W5500-EVB board.

Blynk - build an app for your Arduino project in 5 minutes
Imagine a prototyping board on your smartphone where you drag and drop buttons, sliders, displays, graphs and other functional widgets. And in a matter of minutes these widgets can control Arduino and get data from it.

For more details, please refer to the Blynk official website, http://www.blynk.cc/

STEP 1: Parts

For this instructables, you'll need next things.

Android Mobile Phone or iPhone
- Blynk platform provides both two Apps; Google Android App and Apple iOS app
Blynk App for your phone
- http://www.blynk.cc/getting-started/
WIZnet W5500-EVB board
- Ethernet (W5500 Hardwired TCP/IP chip) and 32-bit ARM® Cortex™-M0 (NXP) based designd evaluation board
- Arduino Pin-compatible (Arduino Shield available)
A computer NXP LPCXpresso IDE installed
- Free Activation needed (Free Edition supports code sizes up to 256 kB after activation)
- LPCXpresso IDE Install and Activation Guide: http://wizwiki.net/wiki/doku.php?id=osh:lpcxpresso...

STEP 2: Download Blynk App and Get the Auth Key Token in the App

You can download Blynk App from http://www.blynk.cc/getting-started/

STEP 3: Download Simple Blynk Library for W5500-EVB

Firmware source code project released on GitHub repository.

https://github.com/Wiznet/BLYNK_LPC11E36_LPCXpress...

STEP 4: Set Your App's Auth Key to the Source Code

Set your App's Auth key to the source code - array Auth[] in main.c (32 bytes)

STEP 5: Build the Project and Program to W5500-EVB

This project based on NXP LPCXpresso IDE.

Project Import to IDE, build and program to W5500-EVB

Refer to NXP MCU Flash programming guide: http://wizwiki.net/wiki/doku.php?id=products:w5500...

STEP 6: Open Blynk App and Add Widgets

Select the Hardware in Blynk app to Arduino UNO.

W5500-EVB is the Arduino pin-compatible board, It's possible to use pin 'D0 ~ D15' and 'A0 ~ A5'

So, please check the W5500-EVB Pinmap and then use the board.

STEP 7: Run!

Enjoy it. Make your own remote controlled / monitor device using W5500-EVB and Blynk.

Cautions

You have to use this example with (1) DHCP client code and Router(DHCP server) or (2) Public IP address.
