Struct I2cSlave

pub struct I2cSlave<'d, T: Instance> { /* private fields */ }

I2CSlave driver.

Implementations

impl<'d, T: Instance> I2cSlave<'d, T>

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

Create a new instance.

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

Wait asynchronously for commands from an I2C master. buffer is provided in case master 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, 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 master read, then fill any remaining read bytes with fill
