I made a prototype board with a W5500 and Atmel ATmega32U4 (connected via SPI). I’d like to set up a simple program to upload to the microcontroller to have the W5500 negotiate with a DHCP server to get an IP address, then send simple commands (HTTP requests to a fixed server).
I don’t really know where to start. I downloaded the Wiznet ioLibrary but it seems to be geared more towards setting up a DHCP server on the W5500 (unless I am mistaken). What I’d really like is a very simple example program showing how to connect to DHCP and send simple messages. Does such a thing exist?
Thanks very much.
