I don't know that my fpga is capable (spartan 3e 100k), but I thought I might like to try to do ethernet first. I remember finding a tutorial weeks ago but forgot to bookmark it, where the instructions had you hook up two io pins directly to an ethernet cable, and you could hardcode an IP address into the chip and ping it. Does anyone know of any like this, or even of the one I speak? (Might even have been verilog, I forget).
Also, at the risk of sounding stupid, can an fpga hook up directly to ethernet? Supposing it is clocked at the right speed, the only consideration is the voltage of utp/ethernet, right? What other sort of hardware would I need to make all that work? Is it anything I can salvage off an old nic?
Thanks in advance, John O.
