Struct stm32wlxx_hal::i2c::I2c1

pub struct I2c1<PINS> { /* private fields */ }

I2C1 peripheral operating in master mode

Implementations

impl<SCL, SDA> I2c1<(SCL, SDA)>

pub fn new( i2c: I2C1, pins: (SCL, SDA), freq_hz: u32, rcc: &mut RCC, pullup: bool, cs: &CriticalSection ) -> Selfwhere SCL: I2c1Scl + PinOps, SDA: I2c1Sda + PinOps,

Configures the I2C peripheral as master with the indicated frequency. The implementation takes care of setting the peripheral to standard/fast mode depending on the indicated frequency and generates values for SCLL and SCLH durations

Panics

• Frequency is greater than 1 MHz
• Resulting TIMINGR fields PRESC, SCLDEL, SCADEL, SCLH, SCLL are out of range

pub fn free(self) -> (I2C1, (SCL, SDA))

Releases the I2C peripheral and associated pins

Trait Implementations

impl<PINS: Debug> Debug for I2c1<PINS>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<PINS> Read for I2c1<PINS>

type Error = Error

Error type

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

Reads enough bytes from slave with address to fill buffer

impl<PINS> Write for I2c1<PINS>

type Error = Error

Error type

fn write(&mut self, addr: u8, bytes: &[u8]) -> Result<(), Self::Error>

Writes bytes to slave with address address

impl<PINS> WriteRead for I2c1<PINS>

type Error = Error

Error type

fn write_read( &mut self, addr: u8, bytes: &[u8], buffer: &mut [u8] ) -> Result<(), Self::Error>

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