Struct I2c 

pub struct I2c { /* private fields */ }

I2C bus master.

Wraps an opaque ove_i2c_t handle provided by the board configuration (the substrate manages the handle’s lifetime; the binding does not own it). Construct via I2c::from_handle with a handle obtained from the BSP layer or board descriptor.

Implementations

impl I2c

pub const unsafe fn from_handle(handle: ove_i2c_t) -> Self

Wrap an existing ove_i2c_t handle.

Safety

• handle must be a valid I2C handle returned by the substrate (typically via the board config / BSP layer).
• The caller is responsible for ensuring no other I2c wrapper exists for the same handle concurrently — the substrate serialises bus access internally, but constructing two wrappers with conflicting trait-impl state is a logic error.

pub fn raw(&self) -> ove_i2c_t

Return the underlying handle. Useful when bridging into the raw FFI for an operation the binding hasn’t surfaced.

pub fn write(&self, addr: u16, data: &[u8], timeout: Duration) -> Result<()>

Write data to an I2C device.

pub fn read(&self, addr: u16, buf: &mut [u8], timeout: Duration) -> Result<()>

Read data from an I2C device.

pub fn write_read( &self, addr: u16, tx: &[u8], rx: &mut [u8], timeout: Duration, ) -> Result<()>

Combined write-then-read with I2C repeated start.

pub fn reg_write( &self, addr: u16, reg: u8, data: &[u8], timeout: Duration, ) -> Result<()>

Write to a single-byte-addressed register.

pub fn reg_read( &self, addr: u16, reg: u8, buf: &mut [u8], timeout: Duration, ) -> Result<()>

Read from a single-byte-addressed register.

pub fn probe(&self, addr: u16, timeout: Duration) -> Result<()>

Probe for a device at the given address (zero-length write, check ACK).

Trait Implementations

Error type

impl I2c for I2c

fn read(&mut self, address: u8, read: &mut [u8]) -> Result<(), Self::Error>

Reads enough bytes from slave with address to fill read.

fn write(&mut self, address: u8, write: &[u8]) -> Result<(), Self::Error>

Writes bytes to slave with address address.

fn write_read( &mut self, address: u8, write: &[u8], read: &mut [u8], ) -> Result<(), Self::Error>

Writes bytes to slave with address address and then reads enough bytes to fill read in a single transaction.

fn transaction( &mut self, address: u8, operations: &mut [Operation<'_>], ) -> Result<(), Self::Error>

Execute the provided operations on the I2C bus.
