Trait Implementations

impl<'a, A: Alarm<'a>, B: Bus<'a, BusAddr8>, P: Pin> AlarmClient for ST77XX<'a, A, B, P>

fn alarm(&self)

Callback indicating the alarm time has been reached. The alarm MUST be disabled when this is called. If a new alarm is needed, the client can call Alarm::set_alarm.

impl<'a, A: Alarm<'a>, B: Bus<'a, BusAddr8>, P: Pin> Client for ST77XX<'a, A, B, P>

fn command_complete( &self, buffer: Option<&'static mut [u8]>, _len: usize, status: Result<(), ErrorCode>, )

Called when set_addr, write or read are complete

impl<'a, A: Alarm<'a>, B: Bus<'a, BusAddr8>, P: Pin> Screen<'a> for ST77XX<'a, A, B, P>

fn get_resolution(&self) -> (usize, usize)

Get a tuple (width, height) with the current resolution (in pixels).

fn get_pixel_format(&self) -> ScreenPixelFormat

Get the current pixel format.

fn get_rotation(&self) -> ScreenRotation

Get the current rotation.

fn set_write_frame( &self, x: usize, y: usize, width: usize, height: usize, ) -> Result<(), ErrorCode>

Sets the write frame.

fn write( &self, data: SubSliceMut<'static, u8>, continue_write: bool, ) -> Result<(), ErrorCode>

Write data from buffer to the selected write frame.

fn set_client(&self, client: &'a dyn ScreenClient)

Set the object to receive the asynchronous command callbacks.

fn set_brightness(&self, _brightness: u16) -> Result<(), ErrorCode>

Set the display brightness value.

fn set_power(&self, enabled: bool) -> Result<(), ErrorCode>

Controls the screen power supply.

fn set_invert(&self, enabled: bool) -> Result<(), ErrorCode>

Controls the color inversion mode.

impl<'a, A: Alarm<'a>, B: Bus<'a, BusAddr8>, P: Pin> ScreenSetup<'a> for ST77XX<'a, A, B, P>

fn set_client(&self, setup_client: &'a dyn ScreenSetupClient)

fn set_resolution(&self, resolution: (usize, usize)) -> Result<(), ErrorCode>

Set the screen resolution in pixels with (X, Y).

fn set_pixel_format(&self, depth: ScreenPixelFormat) -> Result<(), ErrorCode>

Set the pixel format.

fn set_rotation(&self, rotation: ScreenRotation) -> Result<(), ErrorCode>

Set the rotation of the display.

fn get_num_supported_resolutions(&self) -> usize

Get the number of supported resolutions.

fn get_supported_resolution(&self, index: usize) -> Option<(usize, usize)>

Get the resolution specified by the given index.

fn get_num_supported_pixel_formats(&self) -> usize

Get the number of the pixel formats supported.

fn get_supported_pixel_format(&self, index: usize) -> Option<ScreenPixelFormat>

Get the pixel format specified by the given index.
