Required methods

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

Writes a single word to the serial interface

pub fn flush(&mut self) -> Result<(), Error<Self::Error>>

Ensures that none of the previously written words are still buffered

Trait Implementations

impl<Word, Error> Write for dyn Write<Word, Error = Error> + 'static where
    Word: From<u8>, 

pub fn write_str(&mut self, s: &str) -> Result<(), Error>

Writes a string slice into this writer, returning whether the write succeeded.

pub fn write_char(&mut self, c: char) -> Result<(), Error>

Writes a char into this writer, returning whether the write succeeded.

pub fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Glue for usage of the write! macro with implementors of this trait.

Implementors

impl<USCI: SerialUsci> Write<u8> for Tx<USCI>

type Error = Void

pub fn flush(&mut self) -> Result<(), Self::Error>

Due to errata USCI42, UCTXCPTIFG will fire every time a byte is done transmitting, even if there's still more buffered. Thus, the implementation uses UCTXIFG instead. When flush() completes, the Tx buffer will be empty but the FIFO may still be sending.

pub fn write(&mut self, data: u8) -> Result<(), Self::Error>

Check if Tx interrupt flag is set. If so, write a byte into the Tx buffer. Otherwise block on the Tx flag.
