Variables

var (
	ParamAmplitude = dds.ParamAmplitude
	ParamFrequency = dds.ParamFrequency
	ParamPhase     = dds.ParamPhase
)

Params alias dds.Params.

Types

type Config

type Config struct {
	dds.Config `yaml:",inline"`
	ResetPin   gpio.PinIO
	UpdatePin  gpio.PinIO
	SPIPort    spi.Port
}

Config extends dds.Config with hardware specific configuration.

type DDS

type DDS interface {
	driver.Driver

	Reset() error

	Amplitude() float64
	SetAmplitude(float64)

	Frequency() float64
	SetFrequency(float64)

	PhaseOffset() float64
	SetPhaseOffset(float64)

	Sweep() SweepConfig
	SetSweep(SweepConfig)

	Playback() PlaybackConfig
	SetPlayback(PlaybackConfig)

	Exec() error
}

DDS interface represents a direct digital synthesizer device.

type Mockup

type Mockup struct {
	Debug    bool
	HadReset bool
	HadExec  bool
	// contains filtered or unexported fields
}

Mockup implements DDS interface.

Mockup can be used to test the DDS interface without the need of fully functioning hardware present.
