Struct nrf51_hal::Twi

pub struct Twi<T>(/* private fields */);

Implementations

impl<T> Twi<T>

where T: Instance,

pub fn new(twi: T, pins: Pins, frequency: FREQUENCY_A) -> Twi<T>

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

Write to an I2C slave.

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

Read from an I2C slave.

pub fn write_then_read( &mut self, address: u8, wr_buffer: &[u8], rd_buffer: &mut [u8] ) -> Result<(), Error>

Write data to an I2C slave, then read data from the slave without triggering a stop condition between the two.

pub fn free(self) -> (T, Pins)

Return the raw interface to the underlying TWI peripheral.

Error type

impl<T> I2c for Twi<T>

where T: Instance,

fn transaction( &mut self, address: u8, operations: &mut [Operation<'_>] ) -> Result<(), <Twi<T> as ErrorType>::Error>

Execute the provided operations on the I2C bus.

fn read(&mut self, address: A, read: &mut [u8]) -> Result<(), Self::Error>

Reads enough bytes from slave with address to fill read.

fn write(&mut self, address: A, write: &[u8]) -> Result<(), Self::Error>

Writes bytes to slave with address address.

fn write_read( &mut self, address: A, write: &[u8], read: &mut [u8] ) -> Result<(), Self::Error>

Writes bytes to slave with address address and then reads enough bytes to fill read in a single transaction.
