impl<M, BUS> I2c for I2cDevice<'_, M, BUS>

where M: RawMutex, BUS: I2c,

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

Reads enough bytes from slave with address to fill read.

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

Writes bytes to slave with address address.

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

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

fn transaction<'a>( &mut self, address: u8, operations: &mut [Operation<'a>], ) -> Result<(), Self::Error>

Execute the provided operations on the I2C bus.
