PwmChannel Class

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

A single PWM channel opened from a PwmController. Configure Polarity and duty cycle, then call Start to begin driving the output.

public class PwmChannel : IDisposable

Properties​

ChannelNumber​

public int ChannelNumber { get; }

Controller-relative channel index this object represents.

Controller​

public PwmController Controller { get; }

The PwmController that owns this channel.

IsStarted​

public bool IsStarted { get; set; }

True once Start has been called and Stop has not.

Polarity​

public PwmPulsePolarity Polarity { get; set; }

Selects whether the active part of the pulse is high or low.

Methods​

Dispose()​

public void Dispose()

Releases the channel so another caller can open it.

GetActiveDutyCyclePercentage()​

public double GetActiveDutyCyclePercentage()

Returns the most recently set duty cycle as a 0.0..1.0 fraction.

Returns double

SetActiveDutyCyclePercentage(double dutyCyclePercentage)​

public void SetActiveDutyCyclePercentage(double dutyCyclePercentage)

Sets the duty cycle as a 0.0..1.0 fraction of the period.

ParameterTypeDescription
dutyCyclePercentagedouble0.0 = always inactive, 1.0 = always active.

Start()​

public void Start()

Begins generating the configured waveform on the channel.

Stop()​

public void Stop()

Stops the waveform; the pin is parked in its inactive state.
