Required Methods§
sourceasync fn read(&mut self, words: &mut [Word]) -> Result<(), Self::Error>
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

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