Windows IoT Core Extension for Visual Studio Code

About the Windows IoT Core Extension for VS Code


Visual Studio Code is the first code editor and first cross-platform development tool – supporting OS X, Linux, and Windows – in the Visual Studio family.

Windows 10 IoT Core already supports popular boards like Link Removed, Link Removed and Link Removed, and because Node.js continues to see a lot of excitement in the maker community, we have been continuously improving and expanding the Link Removed.

Using Visual Studio Code and the new Link Removed, you can write a Node.js script, deploy it to a Windows IoT Core device and then run it from the development machine of your choice, whether it runs OS X, Linux or Windows.

Install VS Code


To get VS Code go to http://code.visualstudio.com. The setup is quick and easy! If you are new to VS Code, I suggest you check out VS Code Tips and Tricks: https://github.com/Microsoft/vscode-tips-and-tricks

Install Windows IoT Core Extension for Visual Studio Code

• Start VS Code
• Press F1
• Type “Install extensions” and press enter
• Type “iot” in the edit box at the top of the list
• Click the install button on Windows IoT Core Extension for Visual Studio Code

Install Node

• Go to https://nodejs.org/ in a browser
• If you aren’t sure which version to install, then install the LTS version

Deploying the Hello World Sample to Windows IoT Core


To create a simple web server that displays “Hello World,” open a command prompt and execute the following commands:

• md c:hello (directory name/location isn’t important)
• cd c:hello
• npm init (accept all defaults)
• code . // code <space> <period/dot>
• F1 -> iot: Initialize settings.json
• Enter device IP address and desired name
• Enter the username and password to log into the device with. The defaults are “Administrator” and “p@ssw0rd.” If you prefer not to have your username and/or password in a plain text file, delete these lines from the generated .json file and you will be prompted each time they are needed.
• Verify that settings.json is correct by pressing F1 and then typing “iot: Get Device Info.” If the command succeeds you should see output similar to the following:

Link Removed

• Change LaunchBrowserPageNo in settings.json to LaunchBrowserPage
• Add a new file to the workspace by clicking the icon found here. Name it index.js or whatever filename you provided in npm.init.

Link Removed

• Copy and paste code from Link Removed

var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, { 'Content-Type': 'text/plain' });
res.end('Hello World!n');
}).listen(1337);

• To enable logging of your project set the start script in package.json file. The log file will be written to C:datausersDefaultAccountAppDataLocalPackagesNodeScriptHost_dnsz84vs3g3zpLocalStatenodeuwp.log on the device.

{
&amp;quot;scripts&amp;quot;: {
&amp;quot;start&amp;quot;: &amp;quot;node --use-logger index.js&amp;quot;
}
}

• F1 > “iot: Run Remote Script”
• Navigate to http://${deviceip}:1337/ in a browser

Deploying the Blinky Sample to Windows IoT Core

• md c:blinky (directory name/location isn’t important)
• cd c:blinky
• npm init (accept all defaults)
• code . // code <space> <period/dot>
• F1 -> iot: Initialize settings.json
• Enter device IP address and desired name
• Enter the username and password to log into the device with. The defaults are “Administrator” and “p@ssw0rd”. If you prefer not to have your username and/or password in a plain text file, delete these lines from the generated .json file and you will be prompted each time they are needed.
• Wire your circuit as described at Link Removed
• Add a new file to the workspace by clicking the icon found here. Name it index.js or whatever filename you provided in npm.init.

Link Removed

• Copy and paste code from Link Removed

// Copyright (c) Microsoft. All rights reserved.
var http = require('http');
var uwp = require(&amp;quot;uwp&amp;quot;
uwp.projectNamespace(&amp;quot;Windows&amp;quot;
var gpioController = Windows.Devices.Gpio.GpioController.getDefault();
var pin = gpioController.openPin(5);
var currentValue = Windows.Devices.Gpio.GpioPinValue.high;
pin.write(currentValue);
pin.setDriveMode(Windows.Devices.Gpio.GpioPinDriveMode.output);
setTimeout(flipLed, 500);

function flipLed(){
if (currentValue == Windows.Devices.Gpio.GpioPinValue.high) {
currentValue = Windows.Devices.Gpio.GpioPinValue.low;
} else {
currentValue = Windows.Devices.Gpio.GpioPinValue.high;
}
pin.write(currentValue);
setTimeout(flipLed, 500);
}

• F1 > “iot: Run Remote Script”
• You should see the LED blinking

Quick Tour of IoT Commands


All of the commands contributed by this extension are prefixed with “iot:”. To see a list of commands that are contributed by this extension, press F1 and then type iot. You should see something like this:

iot: Get APPX Process Info // get information about UWP applications running on the device

iot: Get Device Info // get information about the Windows IoT Core device

iot: Get Device Name // get the Windows IoT Core device name

iot: Get Extension Info // get information about this extension

iot: Get Installed Packages // get a list of APPX packages installed on the device

iot: Get Process Info // get a list of processes running on the device

iot: Get Workspace Info // get information about the workspace currently open in VS Code

iot: Initialize settings.json // initialize the project settings with iot extension defaults

iot: List Devices // List Windows IoT Core devices on the network

iot: Restart Device // Restart the Windows IoT Core device.

iot: Run Command Prompt // Prompt for a command and then run it on the device

iot: Run Command List // Show a list of commands from settings.json and run the one that is picked

iot: Run Remote Script // Run the current workspace Node.js scripts on the Windows IoT Core device

iot: Set Device Name // Set the device name using the IP Address and name provided

iot: Start Node Script Host // Start the Node.js script host process that works with this extension

iot: Stop Node Script Host // Stop the Node.js script host process that works with this extension

iot: Upload Workspace Files // Upload the files for this workspace but don’t run the project

Get started with Visual Studio.
