Struct I2cSlave 

pub struct I2cSlave<'d, Dm: DriverMode> { /* private fields */ }

I2C Slave driver

Implementations

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

pub fn new(i2c: impl Instance + 'd, config: Config) -> Result<Self, ConfigError>

Create a new I2C slave instance.

pub fn into_async(self) -> I2cSlave<'d, Async>

Reconfigures the driver to operate in Async mode.

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

pub fn into_blocking(self) -> I2cSlave<'d, Blocking>

Reconfigures the driver to operate in Blocking mode.

impl<'d, Dm: DriverMode> I2cSlave<'d, Dm>

pub fn with_sda( self, sda: impl PeripheralInput<'d> + PeripheralOutput<'d>, ) -> Self

Connect a pin to the I2C SDA signal.

pub fn with_scl( self, scl: impl PeripheralInput<'d> + PeripheralOutput<'d>, ) -> Self

Connect a pin to the I2C SCL signal.

pub fn apply_config(&mut self, config: &Config) -> Result<(), ConfigError>

Applies a new configuration.

impl<'d, Dm: DriverMode> I2cSlave<'d, Dm>

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

Listens for a request from the master.

If the master writes to the slave, this method reads data into the provided buffer and returns Command::Write(len). If the master is requesting a read, it returns Command::Read with the SCL line stretched (held low).

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

Responds to a master read request.

Writes the contents of buffer to the TX FIFO, clears the clock stretch, and waits for the transaction to complete.

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

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

Listens for a request from the master asynchronously.

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

Responds to a master read request asynchronously.
