Re:Writing a DHCP server

Sorry about the delay, but here's the comaprison, from my point of view.

The MSP430 part is a very low power, 16-bit processor that can run its' version of LWIP nicely. There's basic support for UDP, TCP, DHCP client and ARP, which I needed for my project. I wrote a DHCP server to run under LWIP. The stack is pretty limited as to number of ports / connections it will support, but it had enough horsepower to do the job for me. I had no need for encryption or other fancy things.

The Luminary port is much more capable and has vastly more options to tweak performance - which has caused me a bit of grief as I had to learn the proper settings by examination in many cases. The code is nowhere near as compact as the MSP430 version, but then agian, the MSP430 code had little use of malloc and such.

In short, if you need Ethernet connectivity on a fairly basic level, and also very low standby power, the MSP430 is a good choice. For more processing power, or fancier protocols, the Luminary part wins.
