CONGRATULATIONS!
You have completed W5100 bootcamp. In addition to the W5100 register I/O code, UDP transmit code, and UDP receive code, you have a basic and flexible W5100 hardware design to work with.
Here’s a hint that will help you determine very early on where your W5100 design stands: Execute only the code through loading the IP address. Load the gateway address, the MAC address, the subnet mask, and the IP address. Don’t open any sockets. At this point, you can PING your W5100 design. If you get good PING returns, your PHY hardware and your W5100 register I/O code are good to go. You’ve also tested and confirmed the operation of your W5100 address, data, and control signals. Bringing up UDP is a fun and easy way to get to know the W5100. The EDTP Internet test panel is a UDP application that runs on your PC. The EDTP Internet test panel is available for download from www.edtp.com.
