Struct st7567s::display::ST7567S

pub struct ST7567S<DI, MODE> { /* private fields */ }

ST7565S display driver

Works in two modes:

• Direct Write Mode (by default): This mode allows you to write directly to the display memory by calling the draw method.
• Buffered Mode: This mode allows you to modify an internal buffer by using methods like set_pixel, clear, or by using the embedded-graphics crate. Once you have made your changes, you can call the flush method to write the buffer to the display.

Implementations

impl<DI: WriteOnlyDataCommand> ST7567S<DI, DirectWriteMode>

pub fn new(display_interface: DI) -> Self

Create new instance of ST7565S driver in DirectWriteMode

Arguments

• display_interface - The interface abstraction from display_interface crate

pub fn into_buffered_graphics_mode(self) -> ST7567S<DI, BufferedMode>

Move driver to buffered mode

impl<DI: WriteOnlyDataCommand> ST7567S<DI, BufferedMode>

pub fn clear(&mut self)

Clear internal buffer

pub fn set_pixel( &mut self, x: u8, y: u8, value: bool ) -> Result<(), DisplayError>

Set pixel in internal buffer

Pixel coordinates starts from top left corner and goes to bottom right corner

pub fn flush(&mut self) -> Result<(), DisplayError>

Send internal buffer to the display

impl<DI: WriteOnlyDataCommand, MODE> ST7567S<DI, MODE>

pub fn init(&mut self) -> Result<(), DisplayError>

Send init commands to the display and turn it on

pub fn reset(&mut self) -> Result<(), DisplayError>

Reset some display parameters to default values: Start Line, Column Address, Page Address and COM Direction. Usually doesn’t need to be called

pub fn draw(&mut self, buffer: &[u8]) -> Result<(), DisplayError>

Send buffer to the display

Buffer represents by 8 pages of 128 columns where 1 byte represents 8 vertical pixels

pub fn bounded_draw( &mut self, buffer: &[u8], top_left: (u8, u8), bottom_right: (u8, u8) ) -> Result<(), DisplayError>

Send part of the buffer to the display. Buffer represents by 8 pages of 128 columns where 1 byte represents 8 vertical pixels

Arguments

• buffer - the entire buffer from which the required part will be sent
• top_left and bottom_right are coordinates of the top left and bottom right corners of the area to be drawn

Trait Implementations

impl<DI: WriteOnlyDataCommand> DrawTarget for ST7567S<DI, BufferedMode>

type Color = BinaryColor

The pixel color type the targetted display supports.

type Error = DisplayError

Error type to return when a drawing operation fails.

fn draw_iter<I>(&mut self, pixels: I) -> Result<(), Self::Error>where I: IntoIterator<Item = Pixel<Self::Color>>,

fn fill_contiguous<I>( &mut self, area: &Rectangle, colors: I ) -> Result<(), Self::Error>where I: IntoIterator<Item = Self::Color>,

Fill a given area with an iterator providing a contiguous stream of pixel colors.

fn fill_solid( &mut self, area: &Rectangle, color: Self::Color ) -> Result<(), Self::Error>

Fill a given area with a solid color.

fn clear(&mut self, color: Self::Color) -> Result<(), Self::Error>

Fill the entire display with a solid color.

impl<DI: WriteOnlyDataCommand> OriginDimensions for ST7567S<DI, BufferedMode>

fn size(&self) -> Size

Returns the size of the bounding box.
