Method Details

Dispose() public method

Stops the SoftPwm if active and calls Dispose on the GPIO pin.

public Dispose ( ) : void
return	void

OnPulseWidthChanged() protected method

Called to raise the PulseWidthChanged event.

protected OnPulseWidthChanged ( double highPulseWidth, double lowPulseWidth ) : void
highPulseWidth	double
lowPulseWidth	double
return	void

OnPwmPulsed() protected method

Called to raise the PwmPulsed event

protected OnPwmPulsed ( ) : void
return	void

SoftPwm() public method

Creates an instance of SoftPwm given an instance of Windows.Devices.Gpio.GpioPin.

public SoftPwm ( Windows.Devices.Gpio.GpioPin pin ) : System
pin	Windows.Devices.Gpio.GpioPin	An instance of Windows.Devices.Gpio.GpioPin to create the SoftPwm on.
return	System

StartAsync() public method

Start the SoftPwm in the GPIO pin.

public StartAsync ( ) : void
return	void

StopAsync() public method

Stop the SoftPwm on the GPIO pin.

public StopAsync ( ) : Task
return	Task

Property Details

PwmPulsed public_oe property

This event is fired for every pulse (after the low pulse). Monitoring of this event can impact the performance of this Soft PWM and it's ability to keep accurate timing.
