Types

type Config

type Config struct {
	Debug        bool    `yaml:"debug"`
	RefClock     float64 `yaml:"refclock"`
	SysClock     float64 `yaml:"sysclock"`
	PLL          bool    `yaml:"pll"`
	SPI3Wire     bool    `yaml:"spi3wire"`
	SPIMaxTxSize int     `yaml:"spimaxtxsize"`
	InverseSinc  bool    `yaml:"inversesinc"`
}

Config holds the configuration of a generic direct digital synthesizer device.

type Param

type Param int

Param defines a signal parameter controlled by the DDS device.

const (
	ParamAmplitude Param = iota
	ParamFrequency
	ParamPhase
)

Common DDS controllable parameters.

type PlaybackConfig

type PlaybackConfig struct {
	Data     []float64
	Trigger  bool
	Duplex   bool
	Interval time.Duration
	Param    Param
}

PlaybackConfig holds the configuration for reading a DDS controllable parameter from memory.

type SweepConfig

type SweepConfig struct {
	Limits   [2]float64
	NoDwells [2]bool
	Duration time.Duration
	Param    Param
}

SweepConfig holds the configuration for sweeping a DDS controllable parameter via the digital ramp of a DDS device.
