Struct nrf52840_hal::Uarte

pub struct Uarte<T>(_);

Interface to a UARTE instance

This is a very basic interface that comes with the following limitations:

• The UARTE instances share the same address space with instances of UART. You need to make sure that conflicting instances are disabled before using Uarte. See product specification:
  • nrf52832: Section 15.2
  • nrf52840: Section 6.1.2

Methods

impl<T> Uarte<T> where
    T: UarteExt, 

pub fn new(
    uarte: T,
    pins: Pins,
    parity: PARITYW,
    baudrate: BAUDRATEW
) -> Uarte<T>

pub fn write(&mut self, tx_buffer: &[u8]) -> Result<(), Error>

Write via UARTE

This method uses transmits all bytes in tx_buffer

The buffer must have a length of at most 255 bytes on the nRF52832 and at most 65535 bytes on the nRF52840.

pub fn read(&mut self, rx_buffer: &mut [u8]) -> Result<(), Error>

Read via UARTE

This method fills all bytes in rx_buffer, and blocks until the buffer is full.

The buffer must have a length of at most 255 bytes

pub fn read_timeout<I>(
    &mut self,
    rx_buffer: &mut [u8],
    timer: &mut Timer<I>,
    cycles: u32
) -> Result<(), Error> where
    I: TimerExt, 

Read via UARTE

This method fills all bytes in rx_buffer, and blocks until the buffer is full or the timeout expires, whichever comes first.

If the timeout occurs, an Error::Timeout(n) will be returned, where n is the number of bytes read successfully.

This method assumes the interrupt for the given timer is NOT enabled, and in cases where a timeout does NOT occur, the timer will be left running until completion.

The buffer must have a length of at most 255 bytes

pub fn free(self) -> T

Return the raw interface to the underlying UARTE peripheral

Trait Implementations

impl<T> Write for Uarte<T> where
    T: UarteExt, 

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

Writes a slice of bytes 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.
