Struct embassy_embedded_hal::shared_bus::asynch::i2c::I2cDeviceWithConfig

pub struct I2cDeviceWithConfig<'a, M: RawMutex, BUS: SetConfig> { /* private fields */ }

I2C device on a shared bus, with its own configuration.

This is like I2cDevice, with an additional bus configuration that’s applied to the bus before each use using SetConfig. This allows different devices on the same bus to use different communication settings.

Implementations

impl<'a, M: RawMutex, BUS: SetConfig> I2cDeviceWithConfig<'a, M, BUS>

pub fn new(bus: &'a Mutex<M, BUS>, config: BUS::Config) -> Self

Create a new I2cDeviceWithConfig.

pub fn set_config(&mut self, config: BUS::Config)

Change the device’s config at runtime

impl<M, BUS> I2c for I2cDeviceWithConfig<'_, M, BUS>

where M: RawMutex + 'static, BUS: I2c + SetConfig + 'static,

async fn read( &mut self, address: u8, buffer: &mut [u8] ) -> Result<(), I2cDeviceError<BUS::Error>>

Reads enough bytes from slave with address to fill buffer.

async fn write( &mut self, address: u8, bytes: &[u8] ) -> Result<(), I2cDeviceError<BUS::Error>>

Writes bytes to slave with address address.

async fn write_read( &mut self, address: u8, wr_buffer: &[u8], rd_buffer: &mut [u8] ) -> Result<(), I2cDeviceError<BUS::Error>>

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

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

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