Struct analog_multiplexer::Multiplexer

pub struct Multiplexer<Pins> {
    pub pins: Pins,
    pub num_channels: u8,
    pub active_channel: u8,
    pub enabled: bool,
}

Provides an interface for setting the active channel and enabling/disabling an 8-channel (74HC4051) or 16-channel (74HC4067) analog multiplexer. It also keeps track of which channel is currently active (active_channel) and provides a convenient num_channels field that can be used to iterate over all the multiplexer's channels.

Fields

pins: Pins

num_channels: u8

active_channel: u8

enabled: bool

Implementations

impl<Pins: Output> Multiplexer<Pins>

pub fn new(pins: Pins) -> Self

Given a 5 or 4-member tuple, (s0, s1, s2, s3, en) or (s0, s1, s2, en) where every member is an OutputPin, returns a new instance of Multiplexer for a 16-channel or 8-channel analog multiplexer, respectively.

NOTE: Some multiplexers label S0-S3 as A-D. They're the same thing.

pub fn set_channel(&mut self, channel: u8)

Sets the current active channel on the multiplexer (0 up to num_channels) and records that state in self.active_channel

pub fn enable(&mut self)

Enables the multiplexer and sets self.enabled = true

pub fn disable(&mut self)

Disables the multiplexer and sets self.enabled = false
