outputting the video buffer to the LCD through USB

[balakbc]

Hi,
I am using Qt-extended-4.4.3 application framework.

I am facing the following limitations:
1. The project is to develop an "application platform" based on ARM processor and has Linux ported on it. Qt will run on this platform. This platform does not have any display capability. All it has to do is to send the display data over USB to a different device which has display unit. Can we configure/port QT to work in such an environment? basically sending display data over USB instead of rendering it itself?
2. The display unit has touch screen capability. User input through touch screen will be sent to the application platform over UART. This information contains X, Y co-ordinates. Can QT accept these X, Y co-ordinates coming from UART? If so can you please give us some rough idea of what kind of work is involved in porting QT?

pls let me know any one has suggestions/solutions for the above .

Rgds,
Bala

What you need to do is to create your own screen driver and your own pointer device. You can find more information about that here: http://doc.trolltech.com/4.5/qt-embedded-linux.html
