I'm sure everyone has seen this, Maybe the next spin would be nice to have a netduido with this new processor... http://ics.nxp.com/p...pc1000/lpc18xx/

Mmmm... I'm thinking something a little faster.... 150Mhz is less than GHI's ChipworksX

Agreed, there are a lot of processors that are faster, but they need external memory. Is the goal to have a low cost board that can leverage shields etc?

There are several boards on the market that are in the price range on the market http://www.embeddeda...product=TS-7500

External memory isn't an issue. Look at GHI's EMX.

LPC185x series could be *very* interesting. I started listing the specs but the post was going to go on forever. This chip supports it all.

Yep. What bothers me a bit about electronics is that after numerous hours of searching, comparing and selecting a perfect component a much better one suddenly appears from source I have never heard of (not that I don't know NXP micros :- ). For my hobby projects I have to stick with whatever is obtainable at reasonable price for single quantity and shipping. I have just found a local vendor (here in Czech Republic) that has AT91SAM7X512 for ~$15 and now I have to check for LPCs - thanks a bunch Posted Image

I cannot speak for Secret Labs, but IMHO a new version of Netduino based on NXP micro is unlikely, because it would require to completely switch the platform: new development tools (although toolchain could remain the same as it usually supports many microcontroller variants, you'd need a dev board, ICD, maybe emulator etc.), new .NET MF port (not sure what can be reused, if anything). This is expensive and time consuming. If anyone releases new board with LPC18xx series, I guess it will be GHI as they already have a lot of experience with NXP micros.

CW2 -- we've worked on .NET MF firmware for NXP micros in the past. We evaluated both Atmel and NXP when we built the Netduino, and the Atmel chips provided the best overall solution. Chris

Chris thanks for the clarification. Now I am looking forward to "How we built the Netduino" series; where a big table comparing features of almost all micros available on the market is introduced for spectators' amusement Posted Image

Unfortunately Atmel don't really seem to offer anything worthwhile in the more powerful series of ARM processors :( It would have been nice if they did offer something that didnt need external ram and/or flash :( NXP really have their act together with ARM chips

When trying to find out info regards the porting kit, i found this chinese blog who have done a guide for their port to a STM32 processor, which like the NXP is a Cortex M3 although not as high spec. http://translate.goo...04/5863524.aspx
