pub struct Twi<T>(_);

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

Return the raw interface to the underlying TWI peripheral.
