This kind of thing begs to be run bare metal (no Linux fbdev using modern 3D GPU with a complex driver stack under the hood). Or some small RTOS at most.

- queuebert 1y agoWouldn't that amount to essentially writing a video card driver?
- RetroTechie 1y agoSure, but targeting hardware suited for this purpose. That is: hardware that does not come with complex 3D GPU. Only some framebuffer(s), and -perhaps- a basic 2D accelerator. Then a driver (if needed at all!), would be trivial, you could take Linux out of the equation & collapse the software stack into a tiny amount of code.
