impl<'d> I2c for I2cDriver<'d>

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

Reads enough bytes from slave with address to fill read.

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

Writes bytes to slave with address address.

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