I think you will need to use a library for that device or something similar to achieved that.

Ok, but how do i can do it?

what function i used for read a external file?

Qprocess??

Thanks

QProcess is for running programme/commands in shell. You need QFile/QTextStream/QDataStream, but you will probably need hardware access to it. I'm not really too familiar with it.

In my specific case, the device driver is wrote by me, and I work with a embedded system, the Qt app has acess the driver for read a value of a A/D converter that is used in my project.
You hope that classes that you indicated for me, work well for this case?

Or is better work acessing a script shell that acess the driver?

Thanks

Use QFile to open your /dev entry and perform read/write as on a regular file.
