A driver for communicating with the Wiznet W5500 SPI Ethernet Controller IC. This driver launches into its own COG then reads and writes to the W5500. Routines are written in both ASM and SPIN to establish communication, transfer data, and change settings. This is a direct port from the W5200_Driver: http://obex.parallax.com/object/658
Included in the zip is a demo to show how to use the driver. The Propeller will offer up a webpage when the IP address is entered into a web browser.
Reset pin time was too short, updated to >500us per the datasheet.
The rxUDP method was moving the UDP header twice and truncating the payload. An offset the length of the UDP header was added to the payload section of rxUDP to correct this.
