W5500 is the Ethernet Controller chip in which TCP/IP protocol has been implemented in hardware logic, so that if you use this chip, you can easily add Ethernet function without porting OS or software TCP/IP stack. As W5500 is controlled by the main MCU, you must port the appropriate driver and application code according to the MCU type.
In this posting, we will introduce W5500 drivers which are used for some major MCUs which are often used for embedded device.
<ioLibrary – WIZnet Official Library>
ioLibrary is the WIZnet’s official library. ‘io’ is the acronym of ‘Internet Offload’ (It’s not about input/output), that means that TCP/IP is offloaded from MCU and independently processed. From the below link, you can download the latest official library for WIZnet chip.

- Arduino Sources : https://github.com/arduino/Arduino/tree/master/libraries/Ethernet
- The Latest version of Arduino.org : https://github.com/arduino-org/Arduino/tree/ide-org-1.6.1.x/libraries/Ethernet2
- WIZnet also provides the W5500 Ethernet shield and its library : https://github.com/Wiznet/WIZ_Ethernet_Library
- FreeRTOS & Libraries for AVR ATmega : If you need the W5500 library to operate on the FreeRTOS, you can use below sources. It is made by Phillip Stevens from Australia
- EHAJO from Germany provides their own Ethernet Shield and its code : http://www.ehajo.de/en/boards/ethernet-shield-wiznet-w5500.html / https://github.com/ehajo/wiznet
<LPC Series / NXP>
- WIZnet provides W5500-EVB for W5500 evaluation. In this evaluation board, NXP’s LPC1136MCU is used for main MCU. https://github.com/Wiznet/W5500_EVB
- Mbed : You can also find W5500 example code and source code from the ARM mbed. If you go to W5500 Ethernet Kit for IoT page, you can download the code.
<STM32 Series (ST Micro)>
- WIZnet Web Module Code : WIZnet has released various web modules using W5500 and STM MCU. Firstly, you can refer to the code for those modules. https://github.com/Wiznet/WIZ550web
- Arduino for STM32 Project : https://github.com/rogerclarkmelbourne/Arduino_STM32 This project has been developed by Seradis. https://github.com/Serasidis/Ethernet_STM; WIZnet W5500, W5200, W5100 ethernet library for 8-bit, 32-bit Arduino and STM32F1 (STM32F103) micro-controllers.
- If you go to the forum W5500 library is (finally) ported” , you can read the success story. Arduino STM project started from Maple Project (http://www.leaflabs.com/about-maple/)
<PIC Series (Microchip PIC18, 24…)>
- ETH WIZ Click is a kind integrated evaluation board developed by a customer in Europe. If you go to http://www.mikroe.com, you can find the basic board and application modules with various functions.
They provide the example code not only for PIC series but also for AVR and ARM
Examples are written for :
- EasyPIC v7 – PIC18F45K22
- EasyPIC v7 for dsPIC30 – dsPIC30F4013
- EasyPIC Fusion v7 – PIC32MX795F512L
- EasyAVR v7 – ATmega32
- EasyMX PRO v7 STM32 – STM32F107VC
- EasyFT90x v7 – FT900
- Firewing Project : As you see below image board, this project provides Arduino compatible hardware and PIC based reference code. The compiler/IDE are provided from the site http://www.firewing.info/pmwiki.php?n=Main.HomePage. W5500 driver is provided from the page http://www.firewing.info/pmwiki.php?n=FirewingUser.W5500 .
