Obviously, prototyping first, then we'll see.
"A prototype is an original type, form, or instance of something serving as a typical example, basis, or standard for other things of the same category." (Wiki[^]) A prototype is the first form on the release item. There is no point in designing a prototype that will be completely different from teh production version - it just wastes your time and money. It can be much (often much, much) bigger, or slower, or contained in a cardboard box (I've done all that) but it needs to share an architecture. :laugh:

I thought this was 20 questions!

It seems to going in that direction.

Okay, allow me to restate; I would like to build 1 device, a test device.
Then: Embedded design - Yes. Power supply - batteries / charger / power consumtion - Yes. Case / housing - Yes. Eprom - Maybe. If you have erase and program equipment, then these are ok for prototype (though in-circuit programmable flash is nicer to use). Processor: Woo! Big choice. Depends on the task complexity / interface requirements. PIC is very good for small devices, but as things get more complex, you need to look at more sophisticated devices. The big crunch here can be cost: ARM is a lovely processor core, but the development tools are seriously expensive compared to PIC etc. Memory: How much? What type? Volatile? Non-volatile? Hardware Design: Are you good with circuit design? Layout? Are you going to lay out a PCB, or breadboard it, or (shudder) wirewrap? All of these will affect the other: For example, fast RAM will need a good multilayer PCB layout, or it will work badly, or not at all. Processor choice will also affect the layout: some chips are only available in 0.5mm leg spacing SMT, or BGA while others are available in DIL packages. I understand you don't want to reveal too much (I wouldn't either), but the best suggestion I can give is: Talk to whoever will design the hardware, and work with what they know. If you know some of it as well, Great! But don't let them design it without input from you: hardware designers are as lazy as we are when they can be, and will design to make their lives easier, not yours!

Aha! I see how this works now, the more specific my question, the more specific your answer! (kidding) I should have thought of that earlier, but as you surmised, I want to be somewhat vague. Your answer is very helpful and now I am going to be even more specific. (By the way, thank you for your time) I am good at design and implementation, I am good with circuit design, and am an electronics hobbyist. In-circuit programmable flash sounds much more fun than using an Eprom since I don't have equipment for it. Processor: Definitely would like to use ARM because of its availability and general hobbyist base, although I don't know enough about other processor types and functionality to decide. I see pricing for some ARM7 controller kits and one-board PC design, which seems to muddy the waters for me with respect to "What can it do?" and "Will it meet my needs?". I guess maybe I should start out with a micro controller hobby board and go from there? That would technically be 'embedded', right? That fits my groove. Would probably be nice to have a JTAG interface as well? Memory: Probably not more than 512mb, non-volatile. Hardware Design: I am good at circuit design and am in the process of building a PIC controlled CNC for circuit board builds and fabrication of the 'product'. No wirewrap, some breadboard, mostly PCB. Thanks again, Herb

ARM is a lovely core to work with, but check: 1) Does the controller kit come with software development tools? Last time I looked, ARM were charging around £5K per user... 2) Be careful which ARM processor you decide on: I have chosen one (SAMSUNG) in the past only for it to go out of production after a total life on six months. OK for a one off, but a PITA for production. 3) If you talk to the importers, processor samples can be available. (A box of chocolates can help here!) Since I normally figure that something is going to go catastrophically wrong with the first built sample, I like to have three or more of every device handy. Normally it doesn't, but I've been burnt by only having one device before. Literally, as it happens... :laugh: 4) JTAG is definitely a goodie. If nothing else, it defines a way to get the data into the in-circuit programmable devices! Good luck!
