Struct linux_embedded_hal::I2cdev

pub struct I2cdev { /* fields omitted */ }

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

Methods

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.

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 Read for I2cdev

type Error = LinuxI2CError

Error type

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

Reads enough bytes from slave with address to fill buffer

impl Write for I2cdev

type Error = LinuxI2CError

Error type

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

Sends bytes to slave with address addr

impl WriteRead for I2cdev

type Error = LinuxI2CError

Error type

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

Sends bytes to slave with address addr and then reads enough bytes to fill buffer in a single transaction
