Printing to real screen about raspberry-pi-os HOT 4 CLOSED

I played around with this same thing, here's a repo i have which is mostly based on what I learned from this repo. I added a video.c which would write things to the screen using the HDMI output: https://github.com/rockytriton/DSOS/tree/master/src

The problem here is that this uses the CPU to draw on the screen, which is ungodly slow. If you have a whole screen of text it takes several seconds to draw it. The only way to fast write to the screen is using the GPU, which I couldn't find any documentation on.

Edit: at one point i did have it writing the printf stuff to the screen but I don't think I ever uploaded that code cause it was so badly slow.
