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
               pwmLed.StartPulse();
               return base.Run();
           }
       }
   }

5. That's it, you're controlling a blue LED with a PWM signal, using Meadow.Foundation's PwmLed driver!
