Struct nrf52832::i2c::TWI

pub struct TWI<'a> { /* private fields */ }

An I2C master device.

A TWI instance wraps a registers::TWI together with additional data necessary to implement an asynchronous interface.

Implementations

impl<'a> TWI<'a>

pub const fn new_twi0() -> TWI<'a>

pub const fn new_twi1() -> TWI<'a>

pub fn configure(&self, scl: Pinmux, sda: Pinmux)

Configures an already constructed TWI.

pub fn set_speed(&self, speed: Speed)

Sets the I2C bus speed to one of three possible values enumerated in Speed.

pub fn clear_events(&self)

Clear all pending events This is useful when switching between a master and slave mode to ensure we start from a clean state.

pub fn disable_interrupts(&self)

pub fn handle_interrupt(&self)

pub fn is_enabled(&self) -> bool
