Struct DisplayDriver 

pub struct DisplayDriver<B: DisplayBus, P: Panel<B>> {
    pub bus: B,
    pub panel: P,
}

The high-level driver that orchestrates drawing operations.

This struct acts as the “glue” between the logical Panel implementation (which knows the command set) and the DisplayBus (which handles the physical transport). It exposes user-friendly methods for drawing pixels, filling rectangles, and managing the display state.

Fields

bus: B

The underlying bus interface used for communication.

panel: P

The panel.

Implementations

impl<B: DisplayBus, P: Panel<B>> DisplayDriver<B, P>

pub fn builder(bus: B, panel: P) -> DisplayDriverBuilder<B, P>

Creates a builder for configuring and initializing a display driver.

Example

let mut display = DisplayDriver::builder(bus, panel)
    .with_color_format(ColorFormat::RGB565)
    .with_orientation(Orientation::Deg270)
    .init(&mut delay).await.unwrap();

pub fn new(bus: B, panel: P) -> Self

Creates a new display driver directly (without builder).

Use builder for a fluent initialization API.

pub async fn init( &mut self, delay: &mut impl DelayNs, ) -> Result<(), DisplayError<B::Error>>

Initializes the display.

pub async fn set_window( &mut self, area: Area, ) -> Result<(), DisplayError<B::Error>>

Sets the window.

Use write_pixels or write_frame if you just want to draw a buffer. Use fill_solid_xxx if you just want to fill an Area.

pub async fn set_color_format( &mut self, color_format: ColorFormat, ) -> Result<(), DisplayError<B::Error>>

Sets the pixel color format.

pub async fn set_orientation( &mut self, orientation: Orientation, ) -> Result<(), DisplayError<B::Error>>

Sets the display orientation.

pub async fn write_pixels( &mut self, area: Area, frame_control: FrameControl, buffer: &[u8], ) -> Result<(), DisplayError<B::Error>>

Writes pixels to the specified area.

pub async fn write_frame( &mut self, buffer: &[u8], ) -> Result<(), DisplayError<B::Error>>

Writes the entire buffer to the display.

impl<B: DisplayBus, P: Panel<B> + PanelSetBrightness<B>> DisplayDriver<B, P>

pub async fn set_brightness( &mut self, brightness: u8, ) -> Result<(), DisplayError<B::Error>>

Sets the display brightness (if supported by the panel).

impl<B: DisplayBus + BusHardwareFill, P: Panel<B>> DisplayDriver<B, P>

pub async fn fill_solid_via_bus( &mut self, color: SolidColor, area: Area, ) -> Result<(), DisplayError<B::Error>>

Fills the area with a solid color using bus auto-fill.

pub async fn fill_screen_via_bus( &mut self, color: SolidColor, ) -> Result<(), DisplayError<B::Error>>

Fills the entire screen with a solid color using bus auto-fill.

impl<B, P> DisplayDriver<B, P>

where B: DisplayBus + BusBytesIo, P: Panel<B>,

pub async fn fill_solid_batch<const N: usize>( &mut self, color: SolidColor, area: Area, ) -> Result<(), DisplayError<B::Error>>

Fills the area with a solid color.

pub async fn fill_screen_batch<const N: usize>( &mut self, color: SolidColor, ) -> Result<(), DisplayError<B::Error>>

Fills the entire screen with a solid color.
