Hi Hamed,

First of all, Connect microcontroller to usb, and write C program on this controller for whatever job you want to be done, PDA will send data to microcontroller to perform proper action. Or, sensor send signal to this microcontroller, and it send digital version to PDA via usb. I am not too good with it and attaching two articles for the same:

Do update us again.
Thank you

Hi Hamed,

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 even that is not the norm. But this could work: 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 you want.

Hope it serves you better.
Do update us again.
Thank you
Anil

hi Anil
first of all i should thank u Anil for your attention to my question.let me clear out my problem......
as i said i have a pda whose os is a wince 5.0.my pda has got a software which is run as soon as i turn on my pda so that i can not see windows' desktop(the software is to use pda mainly as a GPS device and also pdf reader,music player so such things).like any other pda my device has a touchscreen panel which is used for using that software.now i want to change the usage of my pda. i want to use it as a control panel for my stuff in my house( controlling washing machine or oven or any other thing in my house) but i dont know how to uninstall that software and install new one.also, i need to have the address of the usb port in order to send my data out of the pda.let me tell you something else which maybe useful for my explanation....do you know how could i guess my pda's os is a wince 5.0? i figure it out when i looked at the help of the pdf reader on my device.........
thank u so much

Hi Hamed,

I believe you want to know about the version of your PDA, Settings -> System -> About.

I hope it helps you.
Thank you
Anil

Hi Hamed,

Also, You can use the USBXpress SDK for this. It includes a driver for Win CE and an API for communication. This is available for download here:

Go through the link and again update me on this.
Thank you
