Exporting Runnable Jar from project for Wiznet Configuration Tool


This post introduces how to create runnable file from Wiznet github project. This configuration tool provides 2 ways to configure our product in GUI mode and Console mode, so users can choose a way depending on their convenience.


Project file(Github)




Exporting project file

  1. Choose project on Project Browser and click right-button of mouse
  2. Select [Export]-[Java]-[Runnable JAR file]


3. In Launch configuration choose WIZnet_Configuration_Tool and designate exported   file path.


Handling with Project ‘configuration_tool’ is missing required library Error

When this project is imported and builded, following error might occur


This error occurs because Library path is set as absolute path in Eclipse, so this error can be solved following way. (This solution will be updated later)

  1. Select [x]-marked library and click [Edit] button
  2. Select corresponding library in your [Eclipse installed path]\plugins folder(Versions might be different depending on your develop environment)

11.Accept the term and the license agreement. Click “Finish” button.


12.Installing will start


13. After finishing click “Yes” button and restart Eclipse.16

14.After restarting Eclipse, to activate Window Builder click 1. [Window -> Show Toolbar] and [Maximizing button] on upper right side.









[Application Example] Wi-Fi Geolocation Clock


This post introduces an application example about how to identify my current location by connecting (Geolocation) Server using WizFi250 and WIZwiki-W7500, and getting time through NTP(Network Time Protocol) Server.


System Configuration


Hardware Requirements




  • SSD1306 OLED : 128 x 64 dot matrix panel


Hardware Configuration

UART0 RX/TX/CTS/RTS pins of WIZwiki-W7500 board are used to control WizFi250 which Wi-Fi module and It use I2C SDA/SCL pins for using SSD1306 OLED.



Compilation of WizFi250 Geolocation and NTP Example

You can use this WizFi250 Geolocation and NTP example in following link.

WizFi250 Geolocation_NTP Example


Libraries for this example

SSD 1306 Library

To make use of SSD1307 OLED, you need Adrifruit GFX Library. I found some minor bugs using Display() function, so I asked Pull Request to library’s owner.

HTTP Client

As you easily can know by name, HTTP Client Library is used for sending request to and/or receiving response from external web server. In this example, it is used to get Geolocation(Geological code) by connecting to ip-api.com server. If you connect to ip-api.com/csv, then you can get name of country, address, latitude, longitude, TimeZone and so on, in (*.csv) format.


NTP Client

NTP Client Library is used to get UTC from Network Time Server by using UDP commnucation. This example uses a NTP Server Domain(kr.pool.ntp.org) in South Korea. The information acquired from NTP Server is UTC, so 9 hours should be added to get the local time in South Korea.


[Application Examples]Various applications using WIZnet WiFi Modules



WIZnet provides several Embedded WiFi modules such as WizFi210, WizFi220, WizFi250 and WizFi630A. Users can easily implement embedded systems using these WiFi modules. This post introduces various application examples using Wiznet WiFi modules.
