pub struct CD74HC4067<P, E, State> { /* fields omitted */ }

A structure representing the 4 input pins and pin_enable pin

Implementations

impl<P, E> CD74HC4067<P, E, DisabledState> where
    P: OutputPin,
    P: OutputPin,
    P: OutputPin,
    P: OutputPin,
    E: OutputPin, [src]

pub fn new(
    mut pin_0: P,
    mut pin_1: P,
    mut pin_2: P,
    mut pin_3: P,
    mut pin_enable: E
) -> Result<Self, Error<P, E>>[src]

Create a new CD74HC4067 structure by passing in 5 GPIOs implementing the OutputPin trait for a, b, c, d Mux is initially disabled, and all select pins are set low, selecting channel 0.

pub fn release(self) -> (P, P, P, P, E)[src]

Release the 5 GPIOs previously occupied

pub fn enable(
    mut self: Self
) -> Result<CD74HC4067<P, E, EnabledState>, Error<P, E>>[src]

Enable the mux display by pulling pin_enable low If Error::EnablePinError occurs, the struct is dropped.

pub fn set_output_active(&mut self, n: u8) -> Result<(), Error<P, E>>[src]

Enable output n. n must be between 0 and 15 inclusive. If a SelectPinError occurs, the select is left in a possibly unwanted state, but it is disabled here.

    P: OutputPin,
    P: OutputPin,
    P: OutputPin,
    P: OutputPin,
    E: OutputPin, [src]

pub fn disable(
    mut self: Self
) -> Result<CD74HC4067<P, E, DisabledState>, Error<P, E>>[src]

Disable the mux display by pulling pin_enable high
