Getting Started

Hello, World!

  1. Configure your Meadow development environment.

  2. Create a new C# Meadow Application project, name it HelloPulsy.

  3. Plug the longer leg (anode) of a blue LED into pin 13 and the other leg into GND:

  4. Replace the template logic in MeadowApp.cs with the code below, then deploy and run:

    using Meadow;
    using Meadow.Devices;
    using Meadow.Foundation.Leds;

    namespace HelloPulsy
    // Change F7FeatherV2 to F7FeatherV1 for V1.x boards
    public class MeadowApp : App<F7FeatherV2>
    PwmLed pwmLed;

    public override Task Initialize()
    pwmLed = new PwmLed(Device.Pins.D13, TypicalForwardVoltage.Blue);
    return base.Initialize();

    public override Task Run()
    // pulse the LED
    return base.Run();
  5. That's it, you're controlling a blue LED with a PWM signal, using Meadow.Foundation's PwmLed driver!
