Struct St7789 

pub struct St7789<SPI, DC> { /* private fields */ }

ST7789 driver.

Implementations

impl<SPI: SpiDevice, DC: OutputPin> St7789<SPI, DC>

pub const fn new(spi: SPI, dc: DC, panel: Panel, rotation: Rotation) -> Self

Wraps an SPI device and the DC pin. Call init next.

pub async fn init( &mut self, script: &[InitStep], delay: &mut impl DelayNs, ) -> Result<(), Error<<SPI as ErrorType>::Error, <DC as ErrorType>::Error>>

Runs script, then sets RGB565, rotation, inversion, and turns the display on.

pub const fn geometry(&self) -> Geometry

Current drawable window.

pub async fn set_rotation( &mut self, rotation: Rotation, ) -> Result<(), Error<<SPI as ErrorType>::Error, <DC as ErrorType>::Error>>

Changes rotation. Frame memory is not redrawn.

pub async fn command( &mut self, cmd: u8, params: &[u8], ) -> Result<(), Error<<SPI as ErrorType>::Error, <DC as ErrorType>::Error>>

Sends a command followed by its parameters.

pub async fn set_window( &mut self, x0: u16, y0: u16, x1: u16, y1: u16, ) -> Result<(), Error<<SPI as ErrorType>::Error, <DC as ErrorType>::Error>>

Selects the inclusive window (x0, y0)..=(x1, y1) in logical coordinates. Coordinates beyond the visible area are the caller’s responsibility.

pub async fn write_pixels( &mut self, bytes: &[u8], ) -> Result<(), Error<<SPI as ErrorType>::Error, <DC as ErrorType>::Error>>

Streams big-endian RGB565 bytes into the current window.

pub async fn write_rows( &mut self, y: u16, bytes: &[u8], ) -> Result<(), Error<<SPI as ErrorType>::Error, <DC as ErrorType>::Error>>

Writes full-width rows starting at row y. bytes must hold whole rows; it is sent as one contiguous transfer.

pub async fn set_display_on( &mut self, on: bool, ) -> Result<(), Error<<SPI as ErrorType>::Error, <DC as ErrorType>::Error>>

Display on/off. Frame memory is kept while off.

pub async fn set_sleep( &mut self, sleep: bool, delay: &mut impl DelayNs, ) -> Result<(), Error<<SPI as ErrorType>::Error, <DC as ErrorType>::Error>>

Enters (true) or leaves sleep mode. The controller needs 120 ms between the two; this call waits that long after the command.

pub async fn soft_reset( &mut self, delay: &mut impl DelayNs, ) -> Result<(), Error<<SPI as ErrorType>::Error, <DC as ErrorType>::Error>>

Software reset; prefer hard_reset when a reset pin is wired.

pub fn release(self) -> (SPI, DC)

Returns the SPI device and DC pin.
