Source code	GitHub
NuGet package

The PushButton class represents a simple push button, such as a tactile momentary button. To get notified when it’s clicked, subscribe to the Clicked event. If you need to know when the button is held down, subscribe to the PressStarted and PressEnded events.

Code Example

public class MeadowApp : App<F7Micro, MeadowApp>
{
    public MeadowApp()
    {
        PushButton pushButton;

        // Initialize by passing a IDigitalInputPort
        //IDigitalInputPort digitalInputPort = Device.CreateDigitalInputPort(
        //    Device.Pins.D08, 
        //    InterruptMode.EdgeBoth, 
        //    ResistorMode.InternalPullUp, 20);
        //pushButton = new PushButton(digitalInputPort);

        // Initialize by sending Device and Pins
        pushButton = new PushButton(
            Device,
            Device.Pins.D08,
            ResistorMode.InternalPullUp
        );

        pushButton.PressStarted += PushButtonPressStarted;
        pushButton.PressEnded += PushButtonPressEnded;
    }

    void PushButtonPressStarted(object sender, EventArgs e)
    {
        Console.WriteLine("Press Started...");
    }

    void PushButtonPressEnded(object sender, EventArgs e)
    {
        Console.WriteLine("Press Ended...");
    }
}

Class PushButton

Represents a momentary push button with two states that uses interrupts to detect state change

Assembly: Meadow.Foundation.dll

Declaration

public class PushButton : PushButtonBase, IButton, ISensor<bool>, ISensor, IDisposable

Inheritance: System.Object -> Meadow.Foundation.Sensors.Buttons.PushButtonBase

Implements:
Meadow.Peripherals.Sensors.Buttons.IButton, Meadow.Peripherals.Sensors.ISensor<System.Boolean>, Meadow.Peripherals.Sensors.ISensor, System.IDisposable

Properties

DebounceDuration

This duration controls the debounce filter. It also has the effect of rate limiting clicks. Decrease this time to allow users to click more quickly.
