Struct riot_wrappers::i2c::I2CDevice

pub struct I2CDevice { /* private fields */ }

Available on riot_module_periph_i2c only.

An I²C master backed by RIOT’s I2C implementation

Actual transactions on this are performed through the [mbedded_hal_0_2::blocking::i2c] traits implemented by this.

Implementations

impl I2CDevice

pub fn new(dev: i2c_t) -> Self

Create a new I2CDevice from a RIOT descriptor

As all transactions on the bus are gated by acquire / release steps implied in the individual reads or writes, multiple copies of the same device can safely coexist.

Trait Implementations

impl Debug for I2CDevice

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl ErrorType for I2CDevice

type Error = Error

Error type

impl I2c for I2CDevice

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