Any embedded keyboards out there?

Miki

For my little device I need a small little keyboard like on a Sony VAIO UX180.

I'm not trying to build a little PC but a little device you can "chat" with. I already have my ai code built in C++.

Any advice or ideas? Any other way I could go besides propeller?

Thank you.

If your code is already in C++, you could perhaps look at Gumstick or other embedded Linux.

There are a number of small keyboards. Paralax has one for sale, there are some old IBM keyboards that are about as big as their old thinkpad laptop keyboards and if you stay with the propeller, there are some PDA keyboards that people have figured and found at very low prices.

Hi,
As J. A. Streich had mentioned, there was a PDA keyboard (I think originally it was for the Palm) that some people here had worked on.· I am pretty sure Bean on the forum has some for sale (~3 USD) on his site.· The item is labeled "TKB150P Palm Keyboard"

The discussion of the keyboard and .spin code is available here:

Even if you are not using a Propeller, (and are planning on using the same PDA keyboard on a project) you should still find the information useful.

There are several "mini keyboards" available (PS2/USB) that are made PC's that could also be used as well either by using a DIN6 or by cutting the wire and soldering it directly to your device.··Parallax sells one, and there are plenty of other sources (eBay) that you could use to source one as well).· If you are using·a Proto Board, there is already a place to solder a DIN6 connection (~1 USD on a site such as SparkFun), or the accessory kit (~15 USD) could be purchased from Parallax.· If you buy the DIN6 separately you would have to come up with the required resistors (two 100 Ω ¼ watt).· The "Proto Board Accessory Kit" documentation gives more information on the installation:

Hopefully at least some of that information helps!
