ps2 mouse

Basic Example

use ps2_mouse::{Mouse,MouseState};use spinning_top::Spinlock;use x86_64::instructions::port::PortReadOnly;pubstaticMOUSE:Lazy<Spinlock<Mouse>> =Lazy::new(||Spinlock::new(Mouse::new()));// Initialize the mouse and set the on complete event.fninit_mouse(){MOUSE.lock().init().unwrap();MOUSE.lock().set_on_complete(on_complete);}// This will be fired when a packet is finished being processed.fnon_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"fnmouse_interrupt_handler(_stack_frame:&mutInterruptStackFrame){letmut port =PortReadOnly::new(0x60);let packet =unsafe{ port.read()};MOUSE.lock().process_packet(packet);unsafe{PICS.lock().notify_end_of_interrupt(InterruptIndex::Mouse.into());}}
