Trait lpc55_hal::drivers::spi::FullDuplex

pub trait FullDuplex<Word> {
    type Error;
    fn read(&mut self) -> Result<Word, Error<Self::Error>>;
    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.

Required methods

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

Reads the word stored in the shift register

NOTE A word must be sent to the slave before attempting to call this method.

fn send(&mut self, word: Word) -> Result<(), Error<Self::Error>>

Sends a word to the slave
