SignalGenerator Class

Namespace: GHIElectronics.TinyCLR.Devices.Signals · Assembly: GHIElectronics.TinyCLR.Devices.Signals

Drives a pin through a precise sequence of high/low transitions. Suitable for generating IR-remote waveforms, addressable-LED streams (WS281x), and other strict-timing protocols. Optional carrier-frequency modulation is available for IR.

public class SignalGenerator : IDisposable

Constructors

SignalGenerator(GpioPin pin)

public SignalGenerator(GpioPin pin)

Opens a signal generator on the given pin (drives it as a push-pull output).

Parameter	Type	Description
pin	GpioPin

Properties

DisableInterrupts

public bool DisableInterrupts { get; set; }

When true, the write runs with interrupts disabled for sub-microsecond accuracy.

GenerateCarrierFrequency

public bool GenerateCarrierFrequency { get; set; }

When true, the output is modulated with the carrier frequency.

CarrierFrequency

public long CarrierFrequency { get; }

Carrier frequency in Hz used when GenerateCarrierFrequency is true.

IdleValue

public GpioPinValue IdleValue { get; set; }

The level the pin returns to between transitions.

Methods

Dispose()

public void Dispose()

Returns the pin to high-impedance input.

Write(GpioPinValue value)

public void Write(GpioPinValue value)

Sets the pin to a static level.

Parameter	Type	Description
value	GpioPinValue

Write(TimeSpan[] buffer)

public void Write(TimeSpan[] buffer)

Drives the pin through a sequence of timed transitions.

Parameter	Type	Description
buffer	TimeSpan[]	Durations of each segment, alternating active/inactive starting from the current IdleValue's opposite.

Write(TimeSpan[] buffer, int offset, int count)

public extern void Write(TimeSpan[] buffer, int offset, int count)

Drives a slice of the timed transitions.

Parameter	Type	Description
buffer	TimeSpan[]
offset	int
count	int
