Part 2: How

• Stuff You Need

• Device Setup

• Dev Environment Setup

• Hello World

IoT Dashboardhttp://ms-iot.github.io/content/en-US/win10/GetStartedManually.htm

Or Getting Started With Windows IoT And Raspberry PI 3 at http://blog.infernored.com or http://www.leerichardson.com

Basically:

1. Install IoTDashboard

2. Set up a new device

3. Burn Image to SD Card >

Plug In• Ethernet (optional)

• Keyboard/Mouse

• HDMI

• Power

Turn On

(optional)

Set Up Wifi

Default Credentials

Username: Administrator

Password: [user provided]

Part 2: How

• Stuff You Need

• Device Setup

• Dev Environment Setup

• Hello World

Things To Install

• Visual Studio (Any Edition)• Universal Windows App Development Tools

• Windows IoT Core Project Templates• https://visualstudiogallery.msdn.microsoft.com/55b35

7e1-a533-43ad-82a5-a88ac4b01dec

• Enable Developer Mode

Demo Time – Hello World

Part 3: Connectivity

• SignalR

• Azure IoT

• Alljoyn

• Web Server

SignalR Demo• Simple, Fast, Nuget download

• But on ARM

private async Task InitializeSignalR()

{

var cn = new HubConnection("http://mysite.com");

var proxy = cn.CreateHubProxy("MyHub");

proxy.On<string>("itHappened", OnItHappened);

await cn.Start();

}

4. Code

<iot:Capability Name="lowLevelDevices" />

<DeviceCapability Name="109b86ad-f53d-4b76-aa5f-821e2ddf2141"/>

if (LightningProvider.IsLightningEnabled) {

LowLevelDevicesController.DefaultProvider =

LightningProvider.GetAggregateProvider();

var pwmControllers =

await PwmController.GetControllersAsync(LightningPwmProvider.GetPwmProvider());

var pwmController = pwmControllers[1]; // use the on-device controller

pwmController.SetDesiredFrequency(50); // try to match 50Hz

_pin = pwmController.OpenPin(22);

_pin.SetActiveDutyCyclePercentage(.25);

_pin.Start();

}
