# vga
This crate provides vga specific functions, data structures,
and access to various registers.
Memory addresses `0xA0000 -> 0xBFFFF` must be readable and writeable
this crate to work properly.
**Note: This crate is currently experimental and subject to change since it's in active development.**
## Usage
```rust
use vga::colors::{Color16Bit, TextModeColor};
use vga::writers::{ScreenCharacter, TextWriter, Text80x25};
let text_mode = Text80x25::new();
let color = TextModeColor::new(Color16Bit::Yellow, Color16Bit::Black);
let screen_character = ScreenCharacter::new(b'T', color);
text_mode.set_mode();
text_mode.clear_screen();
text_mode.write_character(0, 0, screen_character);
```
