I'm sorry - perhaps I'm a bit tired - but I can't see anything about the hardware. It seems a program that will run on a PC not on an embedded system.

Am I wrong?

There know were some pretty good articles about exactly this sort of thing in the "Circuit Cellar" magazine archives. I do have most of their older magazines on CD-ROM, but don't really have the time to go through them and grab the articles for you. Unless you can Google search it and come up with the Issue number or..??

For all I know, the archive may even be avail online. Good luck. -mpm

What's wrong with an embedded PC solution? Is it a price sensitive application for mass market?, or a one-off project? Embeded PC's come in very small sizes, can run DOS from a small FLASH drive, boot tinstantly, and the application in QBASIC or whatever woul be trivial.

Is this a touch screen application?

This module might be what you need:

It allows you to draw graphics easily on LCD screens from a simple micro (PIC or whatever). All the complex work has been done for you. There are also versions with LCD's built in, and touch screens too.

Well, it's a bit price sensitive but it's not the main problem. I need plenty of reliability (e.g. it should run 24/24 for many days without any crash or loss of performance). A colleague of mine did some projects with Windows Embedded and he told me he wasn't able to make a

100%-stable product.

I know I could use linux or, as you're suggesting,

DOS. This one it's a very good idea. I bet DOS is very stable and the other advantage is the fast boot time.

Not required but welcomed for future upgrades.

Yes! It's the kind of module I was looking for. I hope in the near future they'll add the 800x600 resolution and also another SVGA video page. Currently there is only one and this its not a good thing for smooth animations.

Thank you! Marco / iw2nzm

Thanks for the tip. I'm asking google.

Yep, don't go there.

MSDOS is very stable. Your power supply components or will likely fail, or a power loss will happen before embedded DOS crashes. I know systems that have been up for over 10 years.

Give Atilla (the owner/designer at 4D) an email and see what's coming.

Dave.

There is FreeDOS too, but I have not used it myself so can't vouch for its stability:

Thanks again. Anyway, I've just sent an email to 4D.

Marco / iw2nzm

4d can be a little slow with emails right now. it could be better if you send a message to the group for support, or visit the archives:

Others may be able to answer your questions fairly quickly.

you will also find this product at:

in stock, and shipping world wide.

While it can be compiled or with some more wore work converted to assembler for most any target. It leaves a *lot* of underlying theory out. Try "Computer Graphics" by Edward Angel, ISBN 0-201-13548-5. It somewhat covers the basics, and introduces GKS and PHIGS.
