Struct ps2::PS2Controller

pub struct PS2Controller { /* private fields */ }

An initialized PS/2 controller that can be used to communicate with legacy PS/2 keyboard and mouse devices.

Implementations

impl PS2Controller

pub fn keyboard_ref(&self) -> Option<PS2Keyboard<'_>>

Returns a reference to the keyboard attached to this PS/2 controller.

The keyboard only uses the data port.

pub fn mouse_ref(&self) -> Option<PS2Mouse<'_>>

Returns a reference to the mouse attached to this PS/2 controller.

The mouse uses both the data port and the command/status port.

pub fn write_command(&self, value: HostToControllerCommand)

Writes a command to the PS/2 command port.

Usage Note

Devices attached to the controller should be disabled before writing a command that returns data, otherwise the output buffer may get overwritten.

pub fn read_config(&self) -> ControllerConfigurationByte

Reads and returns the current config value from the PS/2 controller.

pub fn write_config(&self, value: ControllerConfigurationByte)

Writes the given config value to the PS/2 controller.

pub fn status_register(&self) -> ControllerToHostStatus

Reads the PS/2 status port.

pub fn flush_output_buffer(&self)

Clean the data port output buffer, skipping the ControllerToHostStatus output_buffer_full check

pub fn test(&self) -> Result<(), &'static str>

pub fn test_port1(&self) -> Result<(), &'static str>

pub fn test_port2(&self) -> Result<(), &'static str>

pub fn read_controller_test_result(&self) -> Result<(), &'static str>

must only be called after writing the TestController command otherwise would read bogus data
