Struct Keyboard

pub struct Keyboard<'c> { /* private fields */ }

A PS/2 keyboard.

This provides the functionality of a typical PS/2 keyboard, as well as PS/2 devices that act like keyboards, such as barcode scanners, card readers, fingerprint scanners, etc.

Examples

use ps2::Controller;

let mut controller = unsafe { Controller::new() };
let mut keyboard = controller.keyboard();

Implementations

impl<'c> Keyboard<'c>

pub fn set_leds(&mut self, leds: KeyboardLedFlags) -> Result<(), KeyboardError>

Set the state of the keyboard LEDs.

pub fn echo(&mut self) -> Result<(), KeyboardError>

Run a diagnostic echo command.

pub fn get_scancode_set(&mut self) -> Result<u8, KeyboardError>

Get the number corresponding to the current scancode set (1, 2, or 3).

pub fn set_scancode_set( &mut self, scancode_set: u8, ) -> Result<(), KeyboardError>

Set the scancode set number (1, 2, or 3).

pub fn get_keyboard_type(&mut self) -> Result<KeyboardType, KeyboardError>

Attempt to obtain a device identifier for this keyboard.

pub fn set_typematic_rate_and_delay( &mut self, typematic_config: u8, ) -> Result<(), KeyboardError>

Set the typematic repeat rate and delay.

Use the ‘Repeat rate’ and ‘Delay’ tables on this page to create the configuration byte.

pub fn enable_scanning(&mut self) -> Result<(), KeyboardError>

Clear the data buffer and last typematic key, then enable scancodes.

pub fn disable_scanning(&mut self) -> Result<(), KeyboardError>

Reset keyboard to power-on state and disable scancodes.

pub fn set_defaults(&mut self) -> Result<(), KeyboardError>

Reset keyboard to power-on state by clearing the data buffer and restoring all default key settings.

pub fn set_all_keys_typematic(&mut self) -> Result<(), KeyboardError>

Set all keys to typematic only. This only has an effect if scancode set 3 is in use.

pub fn set_all_keys_make_break(&mut self) -> Result<(), KeyboardError>

Set all keys to make/break only. This only has an effect if scancode set 3 is in use.

pub fn set_all_keys_make_only(&mut self) -> Result<(), KeyboardError>

Set all keys to make only. This only has an effect if scancode set 3 is in use.

pub fn set_all_keys_typematic_make_break(&mut self) -> Result<(), KeyboardError>

Set all keys to typematic and make/break. This only has an effect if scancode set 3 is in use.

pub fn set_key_typematic(&mut self, scancode: u8) -> Result<(), KeyboardError>

Set a specific key to typematic only. This only has an effect if scancode set 3 is in use.

pub fn set_key_make_break(&mut self, scancode: u8) -> Result<(), KeyboardError>

Set a specific key to make/break only. This only has an effect if scancode set 3 is in use.

pub fn set_key_make_only(&mut self, scancode: u8) -> Result<(), KeyboardError>

Set a specific key to make only. This only has an effect if scancode set 3 is in use.

pub fn resend_last_byte(&mut self) -> Result<u8, KeyboardError>

Get the last byte sent by the keyboard.

pub fn reset_and_self_test(&mut self) -> Result<(), KeyboardError>

Reset the keyboard and perform a Basic Assurance Test.

Returns KeyboardError::SelfTestFailed if the test fails.
