Struct I2c 

pub struct I2c<'d, M: Mode> { /* private fields */ }

I2C Target Driver.

Implementations

impl<'d, M: Mode> I2c<'d, M>

pub fn blocking_listen(&mut self) -> Result<Request, IOError>

Block waiting for new events

pub fn blocking_respond_to_read(&mut self, buf: &[u8]) -> Result<usize, IOError>

Transmit the contents of buf to the I2C controller.

Returns either an Ok(usize) containing the number of bytes transmitted, or an Error.

pub fn blocking_respond_to_write( &mut self, buf: &mut [u8], ) -> Result<usize, IOError>

Receive data from the I2C controller into buf.

Care is taken to guarantee that we receive at most buf.len() bytes. On success returns Ok(usize) containing the number of bytes received or an Error.

impl<'d> I2c<'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, ) -> Result<Self, SetupError>

Create a new blocking instance of the I2C Target bus driver.

Any external pin will be placed into Disabled state upon Drop.

impl<'d> I2c<'d, Async>

pub fn new_async<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, ) -> Result<Self, SetupError>

Create a new blocking instance of the I2C Target bus driver.

Any external pin will be placed into Disabled state upon Drop.

impl<'d> I2c<'d, Dma<'d>>

pub fn new_async_with_dma<T: Instance>( peri: Peri<'d, T>, scl: Peri<'d, impl SclPin<T>>, sda: Peri<'d, impl SdaPin<T>>, tx_dma: Peri<'d, impl TxDma<T>>, rx_dma: Peri<'d, impl RxDma<T>>, _irq: impl Binding<T::Interrupt, InterruptHandler<T>> + 'd, config: Config, ) -> Result<Self, SetupError>

Create a new async instance of the I2C Controller bus driver with DMA support.

Any external pin will be placed into Disabled state upon Drop, additionally, the DMA channel is disabled.

impl<'d, M: AsyncMode> I2c<'d, M>

where Self: AsyncEngine,

pub async fn async_listen(&mut self) -> Result<Request, IOError>

Asynchronously wait for new events

pub fn async_respond_to_read<'a>( &'a mut self, buf: &'a [u8], ) -> impl Future<Output = Result<usize, IOError>> + 'a

Asynchronously transmit the contents of buf to the I2C controller.

Returns either an Ok(usize) containing the number of bytes transmitted, or an Error.

pub fn async_respond_to_write<'a>( &'a mut self, buf: &'a mut [u8], ) -> impl Future<Output = Result<usize, IOError>> + 'a

Asynchronously receive data from the I2C controller into buf.

Care is taken to guarantee that we receive at most buf.len() bytes. On success returns Ok(usize) containing the number of bytes received or an Error.

Trait Implementations

impl<'d, M: Mode> Drop for I2c<'d, M>

fn drop(&mut self)

Executes the destructor for this type.
