Types

type Config

type Config struct {
	GPIO  GPIOConfig `yaml:"gpio"`
	Debug bool       `yaml:"debug"`
}

Config holds configuration for multiplexer devices.

type Digital

type Digital struct {
	// contains filtered or unexported fields
}

Digital implements Mux for a digital multiplexer.

func NewDigital

func NewDigital(c Config) *Digital

NewDigital creates a new Digital multiplexer using the given pins in the given order for selection.

func (*Digital) Debug

func (d *Digital) Debug() bool

Debug returns true if debug mode is enabled.

func (*Digital) Init

func (d *Digital) Init() error

Init implements Mux interface.

func (*Digital) Select

func (d *Digital) Select(address uint8) (err error)

Select implements Mux interface.

type GPIOConfig

type GPIOConfig struct {
	CS []string `yaml:"cs"`
}

GPIOConfig defines the GPIO pines to use as multiplexer lines.

type Mockup

type Mockup struct {
	Debug    bool
	Selected uint8
}

Mockup implements Mux interface.

func (*Mockup) Init

func (d *Mockup) Init() error

Init implements Mux interface.

func (*Mockup) Select

func (d *Mockup) Select(n uint8) error

Select implements Mux interface.

type Mux

type Mux interface {
	driver.Driver
	// Select configures the multiplexer to address given address
	Select(uint8) error
}

Mux implements a hardware multiplexer driver.
