hi all,
i would like to develop a dongle for pda as my school project, can
anybody give me some information about that?
if somebody can help, please let me know.
Thank you very much in advance!

Dongles basically consist of some active circuitry that returns some code when
given an activation sequence. The activation sequence can be a combination of
characters and control lead changes. You will find this type of dongle more
difficult on a Palm PDA, as they have limited serial control leads.
Sophisticated dongles can include real-time clocks that must be reset with a new
code every year (or whatever) to keep the associated software running.

Which PDA? Different devices have different interface capability.

Will your device require power? If so, will it be self-contained or drain the
batteries of the PDA?

A dongle could be as simple as a CMOS timer, counter, and some gates, powered by
the serial leads. A sequence of X high->low changes on a control lead in a
specified time period could generate a character back on the RD lead.

A PIC could incorporate all the functionality needed, possibly at the expense of
shorter battery life.

Not all dongle are serial devices. In fact, parallel is the most
common.

When talking about serial or parallel then it should be "more" not "most".

That gets me a point back for "weird" :)

Actually the claim is for most often used, not "serial or
parallel".

"Most common" sounds better to me than "more common", and neither is
incorrect. So.... nevermind... I won't say it.

True, but in the specific example of a Palm PDA, it's about the only choice.

USB devices are also available.

Good point. Maybe BlueTooth, and Wi-Fi models too, eh?
Then, a corporation could buy one addressable dongle that carries
all the licenses for the entire firm. Talk about upgrade ease!

And multi-seat piracy, one thing dongles were used to combat.

Dipshit. If it were designed to be a multi-seat validation device,
it would function as such.

Your remark is about as retarded as it gets.

You must be one of those lame dips that goes around stealing loose
WLAN connections. Sorry, dingbat, this schema would not be vulnerable
to such adolescent twits.

Try again.

And multi-seat dongles do exist anyway.

Doh! Since I used to make them, I think I am up to date.

Are they the type I suggested? Blue tooth or other wireless
technology?

That is why I was agreeing with you.
