keyboard input matrix gui application am335x

Laurens Miers

Hi all,

I have a board based on the am335x evm. I want to run a custom Qt Console Application in the matrix gui app. I am trying to get user input via

cin >> variable;

But the application doesn't wait for input but exits immediately. If I run the application from command line through the debug cable, I can give input and everything works fine.

Is it possible to get user input via a keyboard in a matrix application or is this not possible for some reason?

Hi Lawrence,

Please check the information about the QWS_KEYBOARD environment variable here: http://qt-project.org/doc/qt-4.8/qt-embedded-envvars.html

Try to add this variable to the /etc/init.d/matrix-gui-2.0 file and set it corresponding to your keyboard device inside /dev/input/.

Best regards,
Miroslav

Any kind of user interaction when running console based applications are not supported in Matrix.
