I need to drive a led matrix which acts as a monitor. therefore i want to connect it to my beaglebone, which of course runs on a headless debian.
My first thought was to install some gui like lxde, to see if there is any output at all.
but the real question is if i could simply control the hdmi "directly", which means that i want to maybe give the driver or whatever is responsible for driving the hdmi output a picture or video signal which then should appear on the connected monitor. i couldn't find anything on that topic on google because the search term "hdmi" delivers only Home Theater like problems, which doesn't help me.
is there a possibility to achieve the above mentioned? is it possible to "control" the hdmi via command line? which driver or module or whatever is driving the hdmi output on a beaglebone?
thanks in advance!
