Trait Implementations

impl<T> Read<u8> for I2C<T> where
    T: Instance, 

type Error = Error

Error type

fn read<'w>(&mut self, addr: u8, bytes: &'w mut [u8]) -> Result<(), Error>

Reads enough bytes from slave with address to fill buffer

impl<T> Write<u8> for I2C<T> where
    T: Instance, 

Implementation of embedded_hal::blocking::i2c Traits

type Error = Error

Error type

fn write<'w>(&mut self, addr: u8, bytes: &'w [u8]) -> Result<(), Error>

Writes bytes to slave with address address

impl<T> WriteRead<u8> for I2C<T> where
    T: Instance, 

type Error = Error

Error type

fn write_read<'w>(
    &mut self,
    addr: u8,
    bytes: &'w [u8],
    buffer: &'w mut [u8]
) -> Result<(), Error>

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