>are in for a big challenge!

Yes, I know what copper wires are for.. Let me rephrase my question in the
form of my own answer to this..

Basically my microcontroller will use it's I/O ports to send electrical
signals to the lcd/flash (on/off signals I'm assuming? + some V or 0)

Take a LCD with 4 pins (not counting voltage pins, ground, etc)

basically I use 4 I/O's on my microcontroller and connect these together.
How I signal these pins determines what the LCD displays, and how they
signal is based on the hardwired code in the microcontroller...

If this is correct then I think I'm starting to get at least the idea,
enough to start purchasing the stuff I need

And for the record, I know this is going to be a big challenge but I have a
really good idea for a product that I want to start a company with. This
project will basically be a working prototype to show to investors. If I can
get some funding from some VCs or gov agencies, then I'll hire a specialist
who knows better than I, who'll refine the concept.

I don't care how long it takes me. My time frame is 1 year.

You want a character LCD or a graphic LCD? How big? Character LCDs are
easy to deal with, very simple interface, useful up to maybe 40 x 4
characters with the built-in font.

What kind of keyboard?

Or maybe you'll need that specialist to get the founding at all.

Or not : )

I think it really just depends on the complexity.

Really, what I am doing is not ground breaking from a technical standpoint,
but the idea is.

I know some successful VCs and one who launched one of the top 20 most
innovative tech ideas for 2008 (says PC mag).

He probably couldn't figure the square root of 1000 in his head.

10*sqrt(10)

: D

which is 31. something off the top of my head...

For a demo mockup I suggest you get a laptop, palmtop or the like and
program it to do what you want. For the functionality it will not matter
what the hardware is.

> If I can get some funding from some VCs or gov agencies

I wish you luck, but I very much doubt you will. Not because your idea
is not sound, but because this route very rarely works.

> I don't care how long it takes me. My time frame is 1 year.

If you realy don't care how long it takes you (and you are not yet too
old) you will have a good chance. If you do care and it must be shorter
than one year you'd better be prepared to spent that year full time on
this, and I still doubt you will finish it in that time frame. If you
buy existing hardware and limit yourself to the programming side your
chances are much better.

For someone with little or no firmware experience I tend to
agree. If, as you say,

"This project will basically be a working prototype to show to
investors"

instead of producing a finished product (or as near as dammit)
perhaps use some OTS hardware to demo and a proof-of-
concept presentation. I'm sure you can get someone technical
under a non-disclosure agreement to back you up as to what's
feasible and producible

I recently had to exactly what you want to do. Build a modular
device to demonstrate a principle. I KNEW it could be done
but the $$$$ wanted to see one in action. From my perspective
it wasn't totally a waste of a month's unpaid labour (it did force
me to actually design and program the circuit, thereby improving
the concept as work progressed etc. Including two horrible
weeks finding out all the things ISD didn't want you to know
about the ISD5008), but the fact that some blow-dries didn't
initially take my word for it was a little on the nose. All said and
done though, by presenting with a working prototype I jumped
several rungs from credible scruff to shit-hot. And have a working
prototype to prove it ;-)

Then you are probably better off teaming up with someone who has the
relevant depth of hardware and software knowledge, to assist you in building
the prototype. Then when you go searching for capital funds you can show
that you have the necessary experience already on board to make the product
viable.

Sounds  amuch better idea than trying to reinvent fire
yourself.

Somebody else mentioned using a PC as a starting point.

This can be an extremely effective way to get a prrof of
concept demonstrator working. There is a risk that you may
do something that is hard to do on an embedded system
subsequently but that seems unlike;y from what you describe.

You can either simulate the target system on the PC OR

Use an interface to send basic control data to and from a
prototype by whatever interface is best for you. This could
be a cable (pay no attention to the man behind the curtain /
inch thick cable going to that PC over there) or a wireless
link (whether radio, IR etc). You can then have a system
where the demonstrator is effectively a "dumb terminal" with
the work being done on the PC. Done well it can be
inobvious, to a point that you are 'cheating'. You would, of
course, want to point out to the clients that this was a
concept demonstrator and that the 'man behind the curtain'
was still extremely necessary at this stage.
