I thought Atmel was bleeding to death when they were up for sale and declined Microchip's offer. I take it they survived? -- - Rikard - http://bos.hack.org/cv/

They always claimed that they were in fine shape, and had their own plans for restructuring the company more profitably... Time will tell. Now it's pretty tough times for all. BillW

The ATmega328 seems to have shown up, though. BillW

the 328 supply chain is still bumpy ... I just took the last 44 Mouser had and 1500+ are not due in until the end of April ...

Heh, how long was it off that list this last time? I'm using the AVR32 UC3B for a project at the moment, fortunately it's low volume and Digikey and others have many times this volume in stock at any given time so I'm not particularly worried. Still, I keep wishing I could use less of their framework so it'd be easier to port in case of supply issues. -Adam

At the time the project started PIC32 was not available, and the development boards available were not as simple and cheap as, for instance, the EVK1101. I now have a full PIC32 setup, and if I were to start over I'd probably go with PIC32. Incidentally, this 0.7V part would make a very interesting low power arduino - run it off an LR44 button cell for tiny applications... -Adam On Mon, Mar 16, 2009 at 10:19 PM, solarwind <x.solarwind.xspam_OUTgmail.com> wrote: > On Mon, Mar 16, 2009 at 10:55 AM, M.

The arduino is not much more than a programming environment for the AVR, but it's based on the processing language (essentially C with some slightly different 'main' functionality). I'd say it's a step above the basic stamp, since the code is compiled, not interpretted. But it's very easy to get into and use, similar to the stamp. -Adam On Wed, Mar 18, 2009 at 6:54 PM, Adam Field <KILLspamadamKILLspambadtech.org> wrote: >> Incidentally, this 0.7V part would make a very interesting low power >> arduino - run it off an LR44 button cell for tiny applications... > > What is arduino and why is it so popular?
