Initial DHCP request?

#1

I am just getting started on the Ethernet Shield for Arduino using the W5100 chip. It is connected to my Atmel MCU, because I don’t want to use Arduino. I understand everything on the data sheet, but I can’t figure out how to send and receive data to the DHCP server. Can anyone help? Any example code?

Hi devWarrior,

Please, refer to below URL: W5100 DHCP application note.

Thanks,

So I’m guessing I have to manually write my own UDP/TCP protocol stack to be able to send the DHCP requests? Does anyone know if there are any other Wiznet modules that automatically configure the IP, Gateway, and Subnet registers through DHCP?
