Struct esp_ward::display::ili9341::Ili9341Display

pub struct Ili9341Display<T: _esp_hal_spi_master_Instance + 'static, M: IsFullDuplex, RST: OutputPin<Error = Infallible>, DC: OutputPin<Error = Infallible>> {
    pub inner: Display<SPIInterfaceNoCS<Spi<'static, T, M>, DC>, ILI9341Rgb565, RST>,
}

The Ili9341Display struct represents an ILI9341 display connected via SPI.

It encapsulates the lower-level details of communicating with the display and provides a high-level interface for drawing and text rendering.

Fields

inner: Display<SPIInterfaceNoCS<Spi<'static, T, M>, DC>, ILI9341Rgb565, RST>

The inner display instance from the mipidsi crate configured for ILI9341 and RGB565 color mode.

Implementations

impl<T: _esp_hal_spi_master_Instance + 'static, M: IsFullDuplex, RST: OutputPin<Error = Infallible>, DC: OutputPin<Error = Infallible>> Ili9341Display<T, M, RST, DC>

pub fn create_on_spi( spi: Spi<'static, T, M>, reset: RST, dc: DC, delay: Delay ) -> Ili9341Display<T, M, RST, DC>

Constructs a new Ili9341Display.

Initializes the display over SPI, resets it, and prepares it for drawing operations.

Arguments

• spi - The SPI interface used to communicate with the display.
• reset - The pin used to reset the display.
• dc - The data/command control pin.
• delay - The delay provider to use for timing-sensitive operations.

Returns

An initialized Ili9341Display object ready for use.

Trait Implementations

impl<T: _esp_hal_spi_master_Instance + 'static, M: IsFullDuplex, RST: OutputPin<Error = Infallible>, DC: OutputPin<Error = Infallible>> Display for Ili9341Display<T, M, RST, DC>

fn set_pixel(&mut self, x: usize, y: usize)

Sets a single pixel on the display

Arguments

• x - The x coordinate of the pixel.
• y - The y coordinate of the pixel.

fn write_str(&mut self, s: &str)

Writes a string to the center segment of the display using a mid-sized default font style.

Arguments

• s - The string to be written on the display.

fn reset(&mut self)

Resets the display, filling it with a white color.

This can be used to clear the display before drawing new items.

fn write_to_segment( &mut self, segment: DisplaySegment, text: &str, font: MonoTextStyle<'_, Rgb565> )

Writes a string to a specified display segment using the provided font style (you can use default DEFAULT_STYLE_SMALL/MID/LARGE).

Arguments

• segment - The segment of the display where the text will be written.
• text - The string to write to the display.
• font - The font style to use for rendering the text.

fn write_segment_name( &mut self, segment: DisplaySegment, name: &str, font: MonoTextStyle<'_, Rgb565> )

Writes a section name to a specified display segment using the provided font style (you can use default DEFAULT_STYLE_SMALL/MID/LARGE). This is typically used for labeling sections of the display, such as headers or titles.

Arguments

• segment - The segment of the display where the section name will be written.
• name - The name to write to the display.
• font - The font style to use for rendering the name.
