Struct sunrise_keyboard::ps2::PRIMARY_PS2

struct PRIMARY_PS2 {
    __private_field: (),
}

Primary PS2 controller instance on a classical IBM/PC architecture.

Fields

__private_field: ()

Methods from Deref<Target = PS2>

fn handle_control_key(&self, key: HidKeyboardScancode, state: State)

Handle a control key scancode

fn key_to_letter(&self, key: LetterKey) -> char

Gets the letter from the key, accounting for shift and capslock

fn encode_modifiers(&self, state: State) -> u8

Get a bitfield representing the modifiers of this keyboard

fn has_read_key_event(&self) -> bool

Return true if the PS2 keyboard has an key event to read.

fn try_read_key_event(&self) -> Option<KeyEvent>

Tries to read a KeyEvent, grabs more bytes from the port if input is incomplete.

Core function used by both try_read_keyboard_state and try_read_key

fn try_read_keyboard_state(&self) -> Option<HidKeyboardState>

Return a representation of a single key press if any updates is availaible.

Key presses are bufferized: if nobody is calling read_key when the user presses a key, it will be kept in a buffer until read_key is called.

fn read_key(&self) -> char

Waits for a single key press, and return its unicode representation.

Key presses are bufferized: if nobody is calling read_key when the user presses a key, it will be kept in a buffer until read_key is called.

fn try_read_key(&self) -> Option<char>

If a key press is pending, return its unicode representation. This can be used to implement poll-based or asynchronous reading from keyboard.

fn event_irq(&self) -> &ReadableEvent

Get a ReadableEvent for the PS2 IRQ. Waiting on this event will wait until a keypress is detected. Note that once this event is triggered, it won't trigger again until read_key or try_read_key is called.
