Is this diagram perpetuating the myth of COM2 RTS/CTS functionality or is hardware flow control actually working on the NP2? Please see the discussion at http://forums.netdui...ts-always-high/ and the bug at http://netduino.code...com/workitem/5. As far as I can tell, there has never been a shred of evidence supporting the claim that hardware flow control has ever worked on Netduino Plus and I assume that the same is true for Netduino Plus 2. If somebody can prove otherwise for NP2, it would make my day.

Just wanted to join the chorus and say that I'm happy to see the NP2 announcement. When the STM32F4-based Go was announced, I was worried that firmware development for the AT91SAM7X-based NP would suffer as a result of it being based on "the old platform". Whether nor not my fears were well-founded, the NP2 eliminates them. I'll certainly be buying one.

I'm not usre I fully understand all of this but the Amani GTX is like a FPGA device onto which you can program all sorts of really fast logic functions? Could you give some more useful examples of what the Amani GTX can be programmed to do?

Yes, CPLDs are similar to FPGAs. There's an architectural difference between the two but (as far as I can tell) everything I've learned working with the CPLD is portable to FPGAs. I chose the Amani GTX because I liked its form factor and the Altera tools. One web page described CPLDs as "virtual breadboards", which appealed to me because I was in the process of building this project out of 7400 series components -- building the same design *inside* a CPLD seemed a lot simpler than buying parts, designing a PCB, etc. Altera's tools include a library of components that mimic the 7400 series, so that's where I started. By the end of the project, I had started creating my own components using Verilog.

There are a number of example projects here and here. Have a look at "Arduino SRAM Expansion: Supplemental Address Injection and Packet Interception".

Do your serial numbers need to be sequential? Each one being the previous plus one? If not, can you use the MAC address instead of assigning your own serial number?

Just FYI, pins D7/D8 can be used for either RTS/CTS _or_ a third serial port on the Shield Base.

So I read elsewhere, but I think the original post was w.r.t. the "plain old Netduino" (hereinafter "PON"). Still, the Netduino Go looks interesting, so I will almost certainly switch my application onto a Shield Base, once Ethernet and SD are available, and I guess that will finally end my RTS/CTS agony. Glad to see you guys working on new stuff.
