Required Methods

fn set_addr(&self, addr: A) -> Result<(), ErrorCode>

Set the address to write to

If the underlying bus does not support addresses (eg UART) this function returns ENOSUPPORT

fn write( &self, data_width: DataWidth, buffer: &'static mut [u8], len: usize, ) -> Result<(), (ErrorCode, &'static mut [u8])>

Write data items to the previously set address

data_width specifies the encoding of the data items placed in the buffer len specifies the number of data items (the number of bytes is len * data_width.width_in_bytes)

fn read( &self, data_width: DataWidth, buffer: &'static mut [u8], len: usize, ) -> Result<(), (ErrorCode, &'static mut [u8])>

Read data items from the previously set address

data_width specifies the encoding of the data items placed in the buffer len specifies the number of data items (the number of bytes is len * data_width.width_in_bytes)

fn set_client(&self, client: &'a dyn Client)
