Expand description
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§

T: TwimExt,
impl<T> Twim<T>where
T: TwimExt,
pub fn new(twim: T, pins: Pins, frequency: FREQUENCYW) -> Twim<T>
sourcepub fn write(&mut self, address: u8, buffer: &[u8]) -> Result<(), Error>
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.
sourcepub fn read(&mut self, address: u8, buffer: &mut [u8]) -> Result<(), Error>
pub fn read(&mut self, address: u8, buffer: &mut [u8]) -> Result<(), Error>
Read from an I2C slave
