A while back I started looking for a viable solution to adding Ethernet control to my PSoC 5LP project, and unfortunately, I did not find a solution that would work in . After trying several other alternative solutions, I developed the attached implementation of a driver for the W5100 WIZnet device used on the Arduino shield.
This component is a software-only driver (you will need to link it to a SPI port), and it currently supports TCP, ARP, and UDP using the built-in protocols of the W5100 device. It also supports SPI port sharing to allow the application to take advantage of the ability of the SPI bus to handle multiple connected devices. The driver also includes macros for using the driver with the SPIM or SCB components from the Cypress libraries.
This is not a conversion of the C++ code from the arduino library (ref. Element14 100 Projects in 100 days); it was written from scratch as a component for the PSoC devices.
I have tested this using the PSoC 4 and PSoC 5/5LP and I have sucessfully built a 6-port application with a PSoC 5LP. The driver has not yet been fully tested o nthe the PSoC 3, but I believe that it should work based on some initial testing results.
Hope everyone has as much fun using this component as I had writing it!
