Struct AsyncI2c 

pub struct AsyncI2c { /* private fields */ }

Async I2C bus master.

Implementations

impl AsyncI2c

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

Wrap an existing ove_i2c_t handle for async use.

Safety

handle must be a valid I2C handle. Don’t use the same handle through a sync crate::i2c::I2c wrapper while async transactions are in flight.

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

Async write-then-read with repeated start.

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

Async write-only transaction.

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

Async read-only transaction.

Error type

impl I2c for AsyncI2c

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

Execute the provided operations on the I2C bus as a single transaction.

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

Reads enough bytes from slave with address to fill buffer.

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

Writes bytes to slave with address address.

async fn write_read( &mut self, address: A, 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.
