Output to display with Rust bare metal

Question

I'm following along with the Phil-Opp tutorials on creating an OS , and I'm trying to figure out how to control my display/screen, after having successfully gotten VGA output to work. How does one control the display? I'm assuming you have to write a driver... or do you write to specific memory locations like VGA? Would a crate like SDL2, Glium, or something else work on 'bare-metal'?

Answer 1

假设您处于8bpp VGA图形模式（例如模式0x13），则可以通过写入内存地址0xA0000至0xB8000将像素直接写入屏幕。
