Struct I2cRegisters 

pub struct I2cRegisters<I2C> { /* private fields */ }

A register map behind an I2C address.

A read writes the register address and reads the values back in one transaction, with a repeated start between them; a write sends the address and the value.

Implementations

impl<I2C> I2cRegisters<I2C>

pub fn new(bus: I2C, address: u8) -> I2cRegisters<I2C>

Wraps an I2C bus and the part’s 7-bit address.

Arguments

• bus - the I2C bus the part is on.
• address - the part’s 7-bit address.

Returns

The register map.

pub fn address(&self) -> u8

Returns the part’s 7-bit address.

pub fn release(self) -> I2C

Gives back the bus.

Returns

The bus the map was built from.

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

Formats the value using the given formatter.

impl<I2C: I2c> RegisterBus for I2cRegisters<I2C>

type Error = <I2C as ErrorType>::Error

The error the bus underneath reports.

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

Reads consecutive registers starting at first, as many as buffer holds.

fn write_register(&mut self, register: u8, value: u8) -> Result<(), Self::Error>

Writes one register.

fn read_register(&mut self, register: u8) -> Result<u8, Self::Error>

Reads one register.
