Struct linux_embedded_hal::I2cdev

pub struct I2cdev { /* private fields */ }

Newtype around i2cdev::linux::LinuxI2CDevice that implements the embedded-hal traits

Implementations

impl I2cdev

pub fn new<P>(path: P) -> Result<Self, LinuxI2CError>

where P: AsRef<Path>,

See i2cdev::linux::LinuxI2CDevice::new for details.

Methods from Deref<Target = LinuxI2CDevice>

pub fn set_slave_address( &mut self, slave_address: u16 ) -> Result<(), LinuxI2CError>

Set the slave address for this device

Typically the address is expected to be 7-bits but 10-bit addresses may be supported by the kernel driver in some cases. Little validation is done in Rust as the kernel is good at making sure things are valid.

Note that if you have created a device using I2Device::new(...) it is not necesasry to call this method (it is done internally). Calling this method is only necessary if you need to change the slave device and you do not want to create a new device.

pub fn set_smbus_pec(&mut self, enable: bool) -> Result<(), LinuxI2CError>

Enable/Disable PEC support for this device

Used only for SMBus transactions. This request only has an effect if the the adapter has I2C_FUNC_SMBUS_PEC; it is still safe if not, it just doesn’t have any effect.

Trait Implementations

impl Deref for I2cdev

type Target = LinuxI2CDevice

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for I2cdev

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl ErrorType for I2cdev

type Error = I2CError

Error type

impl I2c<u16> for I2cdev

fn transaction( &mut self, address: u16, operations: &mut [I2cOperation<'_>] ) -> Result<(), Self::Error>

Execute the provided operations on the I2C bus.

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

Reads enough bytes from slave with address to fill read.

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

Writes bytes to slave with address address.

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.

impl I2c for I2cdev

fn transaction( &mut self, address: u8, operations: &mut [I2cOperation<'_>] ) -> Result<(), Self::Error>
