Struct ssd1322::interface::spi::SpiInterface

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

A configured DisplayInterface for controlling an SSD1322 via 4-wire SPI.

Implementations

impl<SPI, DC> SpiInterface<SPI, DC> where
    SPI: FullDuplex<u8>,
    DC: OutputPin, 

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

Create a new SPI interface to communicate with the display driver. spi is the SPI master device, and dc is the GPIO output pin connected to the D/C pin of the SSD1322.

Trait Implementations

impl<SPI, DC> DisplayInterface for SpiInterface<SPI, DC> where
    SPI: FullDuplex<u8>,
    DC: OutputPin, 

fn send_command(&mut self, cmd: u8) -> Result<(), Self::Error>

Send a command word to the display’s command register. Synchronous.

fn send_data(&mut self, buf: &[u8]) -> Result<(), Self::Error>

Send a sequence of data words to the display from a buffer. Synchronous.

fn send_data_async(&mut self, word: u8) -> Result<(), Self::Error>

Send a data word to the display asynchronously, using nb style non-blocking send. If the hardware FIFO is full, returns WouldBlock which means the word was not accepted and should be retried later.

type Error = SpiInterfaceError<<DC as OutputPin>::Error, <SPI as FullDuplex<u8>>::Error>
