Struct stm32f4xx_hal::serial::Tx

pub struct Tx<USART, WORD = u8> { /* fields omitted */ }

Serial transmitter

Implementations

impl<USART, WORD> Tx<USART, WORD> where
    USART: Instance, 

pub fn listen(&mut self)

Start listening for a tx empty interrupt event

Note, you will also have to enable the corresponding interrupt in the NVIC to start receiving events.

pub fn unlisten(&mut self)

Stop listening for the tx empty interrupt event

pub fn is_tx_empty(&self) -> bool

Return true if the tx register is empty (and can accept data)

Trait Implementations

impl<USART, PINS, WORD> AsMut<Tx<USART, WORD>> for Serial<USART, PINS, WORD>

fn as_mut(&mut self) -> &mut Tx<USART, WORD>

Performs the conversion.

impl<USART, PINS, WORD> AsRef<Tx<USART, WORD>> for Serial<USART, PINS, WORD>

fn as_ref(&self) -> &Tx<USART, WORD>

Performs the conversion.

impl<USART> PeriAddress for Tx<USART, u8> where
    USART: Instance, 

fn address(&self) -> u32

Returns the address to be used by the DMA stream.

type MemSize = u8

Memory size of the peripheral.

impl<USART> Write for Tx<USART> where
    Tx<USART>: Write<u8>, 

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

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

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

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

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

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

impl<USART> Write<u16> for Tx<USART, u16> where
    USART: Instance, 

type Error = Error

The type of error that can occur when writing

fn bwrite_all(&mut self, buffer: &[u16]) -> Result<(), Self::Error>

Writes a slice, blocking until everything has been written

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

Block until the serial interface has sent all buffered words

impl<USART> Write<u16> for Tx<USART, u16> where
    USART: Instance, 

Writes 9-bit words to the UART/USART

If the UART/USART was configured with WordLength::DataBits9, the 9 least significant bits will be transmitted and the other 7 bits will be ignored. Otherwise, the 8 least significant bits will be transmitted and the other 8 bits will be ignored.

type Error = Error

Write error

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

Ensures that none of the previously written words are still buffered

fn write(&mut self, word: u16) -> Result<(), Self::Error>

Writes a single word to the serial interface

impl<USART> Write<u8> for Tx<USART, u8> where
    USART: Instance, 

type Error = Error

The type of error that can occur when writing

fn bwrite_all(&mut self, bytes: &[u8]) -> Result<(), Self::Error>

Writes a slice, blocking until everything has been written

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

Block until the serial interface has sent all buffered words

impl<USART> Write<u8> for Tx<USART, u8> where
    USART: Instance, 

type Error = Error

Write error

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

Writes a single word to the serial interface

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

Ensures that none of the previously written words are still buffered

impl DMASet<StreamX<DMA1, 6_u8>, MemoryToPeripheral, 4_u8> for Tx<USART2>

impl DMASet<StreamX<DMA2, 6_u8>, MemoryToPeripheral, 5_u8> for Tx<USART6>

impl DMASet<StreamX<DMA2, 7_u8>, MemoryToPeripheral, 4_u8> for Tx<USART1>

impl DMASet<StreamX<DMA2, 7_u8>, MemoryToPeripheral, 5_u8> for Tx<USART6>
