I’d like to introduce wonderful W5500 Application Example posted on the Swordfish compiler site.
Author of this project has already posted his W5100 project on this Swordfish compiler site one month ago.
The author implemented HTTP Server and SOAP Web Service with WIZ550io (Network module based on W5500) and PIC MCU.
The project was explained like this.
This library allow the use of the WIZnet / WIZ550io in Swordfish that mount W5500 ethernet chip. The W5500 has within it all the logic related to the TCP client / server and responds to the ping without special drivers, can enable wake on lan feature and it is for this reason that lends itself to be used quickly and without a great deal of memory. Compared to his older brother W5100 (for which you will find the SF library here) has far fewer pins, a simple buffer management (no more fraction) allowing direct access to the memory in a sequential manner and more available sockets.
The author made the library and also home-made PCB. He shared the board design (Eagle project).
