For amateur radio ATV (Amateur television) I want to create a test card generator with the raspberrypi.
It should not be a problem to do that with a linux distri and an high resolution png of the testcard.
like this: http://www.napierjames.com/index_files/image002.png
But I want to integrate the raspberry in my selfbuild ATV transmitter, by using the composite video. And after powering that on the test card should be available after 2-3 seconds.
Is it should be possible to skip all the operating system stuff and integrate that in a native c++ programm? Or is it nearly impossible to controll the graphic unit without linux?
