# ps2 mouse

This crate provides a basic interface for interacting with a ps2 mouse.

## Basic Example

```rust

use ps2_mouse::{Mouse, MouseState};

use spinning_top::Spinlock;

use x86_64::instructions::port::PortReadOnly;

pub static MOUSE: Lazy> = Lazy::new(|| Spinlock::new(Mouse::new()));

// Initialize the mouse and set the on complete event.

fn init_mouse() {

    MOUSE.lock().init().unwrap();

    MOUSE.lock().set_on_complete(on_complete);

}

// This will be fired when a packet is finished being processed.

fn on_complete(mouse_state: MouseState) {

    println!("{:?}", mouse_state);

}

// An example interrupt based on https://os.phil-opp.com/hardware-interrupts/. The ps2 mouse is configured to fire

// interrupts at PIC offset 12.

extern "x86-interrupt" fn mouse_interrupt_handler(_stack_frame: &mut InterruptStackFrame) {

    let mut port = PortReadOnly::new(0x60);

    let packet = unsafe { port.read() };

    MOUSE.lock().process_packet(packet);

    unsafe {

        PICS.lock()

            .notify_end_of_interrupt(InterruptIndex::Mouse.into());

    }

}

```
