Hello, is it possible to connect a pda, as a Palm, with a
microcontroller using the usb port on the pda and a usb-to-serial
conversion circuit on the micro?

My understanding is that most pda's are USB slave devices
and can not host another USB slave device such as a
usb-to-serial adaptor. There are some USB device called
"USB to go" that have a limited ability to host another
USB device, but that is not the norm.

But this can be the answer: If you use a microcontroller with "USB to
go" functionality (AFAIR there is a AVR with such a USB interface
on-chip) and make the microcontroller the host for the Palm, you're
close to what the OP wants...

There are a couple books that have been written about using PDAs in
robots. I have two of them and I think one is called PDA robotics. I
can't remember how exactly they did it, if they used the usb port or
not. I will have to look it up later.
You may also want to check out www.acroname.com, they have some PDA
robot kits that are pretty cool.

At least acroname used to sell a PDA kit, it seems they don't have it
any more. They used to have an omnidirectional robot that came with
the PDA and everything.
