Developing a Desktop application for interaction with the outer world

[FreddyKay]

Can you just elaborate it a little more , I mean only developing program in qt is not going to help but I need to develop another extra stuff of software for it so that it can communicate or act as connecting link between my Qt app and my development board.

Qt does not offer a Serial Port by default. Youd would need to program one yourself.

An easier way would be to use boost http://www.boost.org/. Look for Serial Port (http://www.boost.org/doc/libs/1_55_0...ial_ports.html). Although you will have to add an extra framework, its worth it. Much easier than developing it yourself in my opinion.

EDIT://

just looked it up and I am sorry. Qt DOES in fact offer a QSerialPort class, which you could use. Seems pretty straight forward. AFAIK its implemented since Qt5.3.
