Struct I2cSlave 

pub struct I2cSlave<'d, M: Mode> { /* private fields */ }

I2CSlave driver.

Implementations

impl<'d> I2cSlave<'d, Blocking>

pub fn new_blocking<T: Instance>( _peri: Peri<'d, T>, scl: Peri<'d, impl SclPin<T>>, sda: Peri<'d, impl SdaPin<T>>, config: Config, ) -> Self

Create a new instance in blocking mode.

impl<'d> I2cSlave<'d, Async>

pub fn new<T: Instance>( _peri: Peri<'d, T>, scl: Peri<'d, impl SclPin<T>>, sda: Peri<'d, impl SdaPin<T>>, _irq: impl Binding<T::Interrupt, InterruptHandler<T>>, config: Config, ) -> Self

Create a new instance in async mode.

impl<'d, M: Mode> I2cSlave<'d, M>

pub fn reset(&mut self)

Reset the i2c peripheral. If you cancel a respond_to_read, you may stall the bus. You can recover the bus by calling this function, but doing so will almost certainly cause an i/o error in the master.

pub fn blocking_listen(&mut self, buffer: &mut [u8]) -> Result<Command, Error>

Wait for a command from an I2C master, blocking the caller until one arrives.

buffer is provided in case the controller does a ‘write’, ‘write read’, or ‘general call’, and is unused for ‘read’.

pub fn blocking_respond_to_read( &mut self, buffer: &[u8], ) -> Result<ReadStatus, Error>

Respond to an I2C master READ command, blocking the caller until done.

pub fn blocking_respond_till_stop(&mut self, fill: u8) -> Result<(), Error>

Respond to reads with the fill byte until the controller stops asking, blocking the caller.

pub fn blocking_respond_and_fill( &mut self, buffer: &[u8], fill: u8, ) -> Result<ReadStatus, Error>

Respond to a master read, then fill any remaining read bytes with fill, blocking the caller.

impl<'d> I2cSlave<'d, Async>

pub async fn listen(&mut self, buffer: &mut [u8]) -> Result<Command, Error>

Wait for a command from an I2C master.

buffer is provided in case the controller does a ‘write’, ‘write read’, or ‘general call’, and is unused for ‘read’.

pub async fn respond_to_read( &mut self, buffer: &[u8], ) -> Result<ReadStatus, Error>

Respond to an I2C master READ command.

pub async fn respond_till_stop(&mut self, fill: u8) -> Result<(), Error>

Respond to reads with the fill byte until the controller stops asking.

pub async fn respond_and_fill( &mut self, buffer: &[u8], fill: u8, ) -> Result<ReadStatus, Error>

Respond to a master read, then fill any remaining read bytes with fill.
