Struct I2cTarget 

pub struct I2cTarget<'d, M: Mode> { /* private fields */ }

I2C Target driver.

Implementations

impl<'d> I2cTarget<'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>> + 'd, config: Config, target_config: Config, ) -> Result<Self, ConfigError>

Create a new asynchronous I2C target driver using interrupts The config reuses the i2c controller config to setup the clock while target_config configures i2c target specific parameters.

pub fn reset(&mut self) -> Result<(), ConfigError>

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 controller.

impl<'d> I2cTarget<'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, target_config: Config, ) -> Result<Self, ConfigError>

Create a new blocking I2C target driver. The config reuses the i2c controller config to setup the clock while target_config configures i2c target specific parameters.

pub fn reset(&mut self) -> Result<(), ConfigError>

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 controller.

impl<'d, M: Mode> I2cTarget<'d, M>

pub fn flush_tx_fifo(&mut self)

Blocking function to empty the tx fifo

This function can be used to empty the transmit FIFO if data remains after handling a ‘read’ command (LeftoverBytes).

impl<'d> I2cTarget<'d, Async>

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

Wait asynchronously for commands from an I2C controller. buffer is provided in case 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 controller ‘read’ command, asynchronously.

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 controller read, then fill any remaining read bytes with fill
