Struct esp32c2_hal::i2c::I2C

pub struct I2C<T> { /* private fields */ }

I2C peripheral container (I2C)

Implementations

impl<T> I2C<T>where
    T: Instance,

pub fn new<SDA, SCL>(
    i2c: T,
    sda: SDA,
    scl: SCL,
    frequency: Rate<u32, 1, 1>,
    peripheral_clock_control: &mut PeripheralClockControl,
    clocks: &Clocks
) -> Result<I2C<T>, SetupError>where
    SDA: OutputPin + InputPin,
    SCL: OutputPin + InputPin,

Create a new I2C instance This will enable the peripheral but the peripheral won’t get automatically disabled when this gets dropped.

pub fn free(self) -> T

Return the raw interface to the underlying peripheral

Trait Implementations

impl<T> Read<u8> for I2C<T>where
    T: Instance,

type Error = Error

Error type

fn read(
    &mut self,
    address: u8,
    buffer: &mut [u8]
) -> Result<(), <I2C<T> as Read<u8>>::Error>

Reads enough bytes from slave with address to fill buffer

impl<T> Write<u8> for I2C<T>where
    T: Instance,

type Error = Error

Error type

fn write(
    &mut self,
    addr: u8,
    bytes: &[u8]
) -> Result<(), <I2C<T> as Write<u8>>::Error>

Writes bytes to slave with address address

impl<T> WriteRead<u8> for I2C<T>where
    T: Instance,

type Error = Error

Error type

fn write_read(
    &mut self,
    address: u8,
    bytes: &[u8],
    buffer: &mut [u8]
) -> Result<(), <I2C<T> as WriteRead<u8>>::Error>

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