Hello everyone,
I am writing a system that displays a certain pattern on a specified monitor.
Since I am not using an OS GUI to present the frames, but rather streaming it through each of the HDMI out port of the raspberry pi, I read this is done by controlling the frame buffers of the ports.
For some reason I only have /dev/fb0 and not /dev/fb1.
My question is:
Do I need to have two different frame buffers, one for each port in order to display different frames to each HDMI out port?
If so, how can I find where fb1 is, if not what is the best way to do it?
