Struct pcf857x::Pcf8574a

pub struct Pcf8574a<I2C> { /* fields omitted */ }

Device driver

Methods

impl<I2C, E> Pcf8574a<I2C> where
    I2C: Write<Error = E>, 

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

Create new instance of the device

pub fn destroy(self) -> I2C

Destroy driver instance, return I²C bus instance.

pub fn set(&mut self, bits: u8) -> Result<(), Error<E>>

Set the status of all I/O pins.

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

Set the status of all I/O pins repeatedly by looping through each array element

pub fn split<'a>(&'a self) -> Parts<'a, Pcf8574a<I2C>, E>

Split device into individual pins

impl<I2C, E> Pcf8574a<I2C> where
    I2C: Read<Error = E> + Write<Error = E>, 

pub fn get(&mut self, mask: &PinFlag) -> Result<u8, Error<E>>

Get the status of the selected I/O pins. The mask of the pins to be read can be created with a combination of PinFlag::P0 to PinFlag::P7.

pub fn read_array(
    &mut self,
    mask: &PinFlag,
    data: &mut [u8]
) -> Result<(), Error<E>>

Get the status of the selected I/O pins repeatedly and put them in the provided array. The mask of the pins to be read can be created with a combination of PinFlag::P0 to PinFlag::P7.
