Trait embedded_hal_async::spi::SpiBusRead

pub trait SpiBusRead<Word: 'static + Copy = u8>: SpiBusFlush {
    type ReadFuture<'a>: Future<Output = Result<(), Self::Error>>
    where
        Self: 'a;

    fn read<'a>(&'a mut self, words: &'a mut [Word]) -> Self::ReadFuture<'a>;
}

Read-only SPI bus

Required Associated Types

type ReadFuture<'a>: Future<Output = Result<(), Self::Error>>
where
    Self: 'a

Future returned by the read method.

Required Methods

fn read<'a>(&'a mut self, words: &'a mut [Word]) -> Self::ReadFuture<'a>

Read words from the slave.

The word value sent on MOSI during reading is implementation-defined, typically 0x00, 0xFF, or configurable.

Implementations are allowed to return before the operation is complete. See (the docs on embedded-hal)embedded_hal::spi::blocking for details on flushing.
