Hi!

I got these old PocketPCs and wondered if there is a possibility to interface some of the
components inside them.

I am by no means a real engineer just a time to time arduino hobbyist and my equipment is just a
multimeter and a "DSO Nano" (http://www.exp-tech.de/Hacking---Measurement/product-158.html).
So I dont own a real logic analyser etc. :(

Do you think its still possible to interface eg. the displays and touchscreens of these devices? Maybe
there are some libs Im missing for such projects/interfacing?

Thanks for your time!

It should be possible, but unless you have access to the schematics for these devices it will likely require quite a bit of detective work/reverse engineering to identify the specific parts of the circuitry that need to be interfaced with.  With luck, most of the used ICs would be commercially available and would have datasheets to simplify this process.  However if these devices rely heavily custom ICs, like ASICs, driving their displays and touch sensors it won't be impossible, but will likely require so much experimentation that it would be impractical.

Before you start, try Googling the words "tear down" along with "PocketPC" or the specific model numbers you have.  If someone has gone through the process of taking apart and thoroughly examining one or more of these PockPCs it will help you determine if this project is feasible enough to pursue further.

I think will be incredibly difficult, far more effort than the screens are worth.

You can get screens like that for under $20 new, designed for Arduino, eg. http://www.ebay.com/sch/i.html?_nkw=arduino+tft+display


No, I don't answer questions sent in private messages (but I do accept thank-you notes...)

I agree; without documentation on the PocketPCs, and your limited equipment resources, it will be quite a challenge.

Hmm seems its not worth the time hacking inside
these devices. Considering using maybe 2-3 weeks of constant
investigation compared to just buy a 20,- bucks
display that just works... I will sell them on ebay, maybe
somebody wants to do so :)

Thank you all!
