Trait embedded_hal_async::spi::SpiBusRead

pub trait SpiBusRead<Word: 'static + Copy = u8>: SpiBusFlush {
    async fn read(&mut self, words: &mut [Word]) -> Result<(), Self::Error>;
}

Read-only SPI bus

Required Methods

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

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.
