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.

  • 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
