qcolorcheck

A Qt app for checking colors on a display.

Used for testing new touchscreen drivers to make sure I got the color mapping correct.

Build natively

Assuming Qt dev libraries and headers are already installed.

$ qmake && make

Operation

The UI runs fullscreen and shows some bands of Red, Green and Blue for 15 seconds before automatically shutting down.

Running without X using Qt5

$ ./qcolorcheck -platform linuxfb
