Struct SpiInterface

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

Async SPI interface for MIPI DCS displays.

This struct implements the Interface trait for SPI-based displays, using an async SpiDevice and a data/command (DC) output pin. Unlike the original mipidsi version, this async variant does not use an internal buffer; all pixel data is sent directly from the provided slice.

Use SpiInterface::new to construct, and SpiInterface::release to deconstruct and recover the SPI and DC resources.

Implementations

impl<SPI, DC> SpiInterface<SPI, DC>

where SPI: SpiDevice, DC: OutputPin,

pub fn new(spi: SPI, dc: DC) -> Self

Create a new async SPI interface from an SPI device and DC pin.

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

Release the DC pin and SPI peripheral back, deconstructing the interface.

Trait Implementations

impl<SPI, DC> Interface for SpiInterface<SPI, DC>

where SPI: SpiDevice, DC: OutputPin,

async fn send_command( &mut self, command: u8, args: &[u8], ) -> Result<(), Self::Error>

Send a command and its arguments to the display controller.

The DC pin is set low for the command byte, then high for the argument bytes.

async fn send_data_slice( &mut self, data: &[Self::Word], ) -> Result<(), Self::Error>

Send a slice of pixel or data bytes to the display controller.

The data is sent as-is over SPI, with the DC pin assumed to be high.
