Struct esp32c3_hal::i2c::I2C

pub struct I2C<'d, T> { /* private fields */ }

I2C peripheral container (I2C)

Implementations

impl<'d, T> I2C<'d, T>where T: Instance,

pub fn new<SDA, SCL>( i2c: impl Peripheral<P = T> + 'd, sda: impl Peripheral<P = SDA> + 'd, scl: impl Peripheral<P = SCL> + 'd, frequency: Rate<u32, 1, 1>, peripheral_clock_control: &mut PeripheralClockControl, clocks: &Clocks<'_> ) -> I2C<'d, T>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.

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
