Hi
I've asked this question directly of Altera sales and gotten a vague answer. But I need a specific answer so I know whether to bid a task. My customer needs to translate UDP over ethernet messages into a serial format. My plan would be to use Nios in an FPGA togther with the LAN91C111 Mac/Phy. The Nios program to convert from a UDP payload into the proprietary serial format is straightforward. The question is how much code must be written to talk to the 91C111 and send/receive UDP packets. My impression is that the LWIP software package provided on this site does 90% of the job. My impression is: 1. It will send and received UDP packets and does everything necessary to run the 91C111; 2. Does NOT require any purchased OS 3. Can be used royalty free 4. And it really, actually works. Am I right? Is this the ticket? If not, are there any alternatives? Writing the whole thing from scratch is way beyond the scope that could be considered. Thanks in advanceLink Copied

Hi Mhirsch,
in order to confirm you thougts: you are absolutely wright. The lwIP-stack can do all of this. You do not need much code in order to send/receive udp-messages. Most of it is handled by the stack. So if you are looking for a royalty-free, stand-alone stack, the lwIP-stack is exactly what you need. Cheers, Danny
