Struct I2cDevice 

pub struct I2cDevice<I2C> {
    pub i2c: I2C,
    pub address: u8,
}

Helper struct for I2C operations.

Fields

i2c: I2C

The I2C bus.

address: u8

The device address.

Implementations

impl<I2C, E> I2cDevice<I2C>

where I2C: I2c<Error = E>,

pub fn new(i2c: I2C, address: u8) -> Self

Create a new I2cDevice.

pub fn write(&mut self, data: &[u8]) -> Result<(), E>

Write bytes to the device.

pub fn read(&mut self, buf: &mut [u8]) -> Result<(), E>

Read bytes from the device.

pub fn write_read(&mut self, write: &[u8], read: &mut [u8]) -> Result<(), E>

Write bytes and then read bytes (Repeated Start).

pub fn write_reg(&mut self, reg: u8, value: u8) -> Result<(), E>

Write a byte to an 8-bit register.

pub fn read_reg(&mut self, reg: u8) -> Result<u8, E>

Read a byte from an 8-bit register.

pub fn read_regs(&mut self, reg: u8, buf: &mut [u8]) -> Result<(), E>

Read multiple bytes starting from an 8-bit register.

pub fn write_reg16_u8(&mut self, reg: u16, value: u8) -> Result<(), E>

Write a byte to a 16-bit register (Big Endian address).

pub fn write_reg16_u16(&mut self, reg: u16, value: u16) -> Result<(), E>

pub fn read_reg16_u8(&mut self, reg: u16) -> Result<u8, E>

Read a byte from a 16-bit register (Big Endian address).

pub fn read_reg16_u16(&mut self, reg: u16) -> Result<u16, E>
