Initial communication

TCP/IP Chip W5500

Finally, after much searching I figured out how to remap the SPI1 pins on the 9S12DXP512. Suddenly I have proper SPI communications. After reading out the Common Register block I get:
Mode 0
Gateway Address 192.168.1.1
Subnet Mask FF, FF, FF, 00
Source MAC Address 00, 08, DC, 1D, 4C, 4F
Source IP Address 192.168.1.2

The I wrote out new parameters
Mode 0
Gateway Address 192.168.0.1
Subnet Mask FF, FF, FF, 00
Source MAC Address 00, 08, DC, 1D, 4C, 4F
Source IP Address 192.168.0.125

Open up Command.exe

Ping statistics for 192.168.0.125:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 1ms, Maximum = 2ms, Average = 1ms

SPI bit rate is 10Mbps. I now know i can read and write to it. Next step is to send it an UDP packet from an application running on the PC.
Step one. Determine how to configure the socket for UDP and verify the contents of the packet.

Hi,
For sending UDP data with UDP socket,
Fisrt, Open socket with UDP mode & Source port number.
Second, copy a data to Socket TX buffer.
Third, Request to send the data with SEND command.
Finally Wait to complete SEND command.

We provide the example for sending UDP on our wiki site.
For more detail, refer to ioLibrary_BSD & Loopback example.
