Struct nrf52840_hal::Twim

pub struct Twim<T>(_);

Interface to a TWIM instance

This is a very basic interface that comes with the following limitation: The TWIM instances share the same address space with instances of SPIM, SPIS, SPI, TWIS, and TWI. For example, TWIM0 conflicts with SPIM0, SPIS0, etc.; TWIM1 conflicts with SPIM1, SPIS1, etc. You need to make sure that conflicting instances are disabled before using Twim. Please refer to the product specification for more information (section 15.2 for nRF52832, section 6.1.2 for nRF52840).

Implementations

impl<T> Twim<T>where
    T: TwimExt,

pub fn new(twim: T, pins: Pins, frequency: FREQUENCYW) -> Twim<T>

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

Write to an I2C slave

The buffer must have a length of at most 255 bytes.

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

Read from an I2C slave

pub fn write_then_read(
    &mut self,
    address: u8,
    wr_buffer: &[u8],
    rd_buffer: &mut [u8]
) -> Result<(), Error>

Write data to an I2C slave, then read data from the slave without triggering a stop condition between the two

The buffer must have a length of at most 255 bytes.

pub fn free(self) -> T

Return the raw interface to the underlying TWIM peripheral
