Trait cortex_m::prelude::_embedded_hal_spi_FullDuplex

pub trait _embedded_hal_spi_FullDuplex<Word> {
    type Error;
    pub fn read(&mut self) -> Result<Word, Error<Self::Error>>;
    pub fn send(&mut self, word: Word) -> Result<(), Error<Self::Error>>;
}

Full duplex (master mode)

Notes

• It’s the task of the user of this interface to manage the slave select lines

• Due to how full duplex SPI works each read call must be preceded by a send call.

• Some SPIs can work with 8-bit and 16-bit words. You can overload this trait with different Word types to allow operation in both modes.
