Git hub connect the dots и windows iot

- THIS PROJECT IS DEPRECATED AND NO LONGER UNDER ACTIVE MAINTENANCE

ConnectTheDots.io is an open source project created by Microsoft to help you get tiny devices connected to Microsoft Azure IoT and to implement great IoT solutions taking advantage of Microsoft Azure advanced analytic services such as Azure Stream Analytics and Azure Machine Learning.

The project is built with the assumption that the sensors get the raw data and format it into a JSON string. That string is then sent to Azure IoT Hub, from which a Web app gathers the data and displays it as a chart.
Optional other functions of the Azure cloud include detecting and displaying alerts and averages, however this is not required.

The JSON string is sent to Azure IoT Hub whether directly by the sensor device if it is capable of connecting to Azure IoT Hub or through a multi-protocol Gateway, which is how the Getting Started with Pi and Arduino sample does it.
More details on each of those options are below.

In this project there are code samples, configuration scripts and guides that will help you set up devices and sensors, and configure Microsoft Azure services to view and analyze the data produced by those devices. Some of these samples have been provided by Microsoft, others by third parties; we encourage everyone to submit code samples or configuration documentation to grow this project.

This project contains several device samples all aimed at helping you connect your devices to Azure IoT, as well as visualize and gain insight from your data. Check out all the samples below, or follow the getting started walkthrough to learn more. Then, add some of your devices to the project!

We encourage the community to contribute to the project! See Contribute page for details.

What’s new in the V2?

Plenty!
The main change is the use of Azure IoT Hub instead of Event Hubs for connecting devices to the Cloud, but here is a list of what’s new in V2

  • Migrated from Event Hubs to Azure IoT Hub for the devices connectivity to Azure IoT: IoT Hub offers a better security with a per device authentication, along with a bidirectional messaging infrastructure.
  • Replaced the Azure Prep tool with an ARM Template: you can now deploy the whole solution (including the WebSite) from a command line not only on Windows, but also no a Mac or a Linux machine!
  • Updated devices samples
    • Updated all the node.js samples to use the Azure IoT Hub SDK
    • Removed old devices samples (Galileo, .Net Micro Framework)
    • Updated the Gateway code to use Azure IoT Hub device SDK
    • Upgraded WP8 samples (Simulated Sensors and MS Band) to Windows 10 UWP apps
    • Added Xamarin samples
    • Added a sample for ESP8266 chips

Where is the V1 if I still want to use the old fashion way (using Event Hub)?

The V1 has been tagged and you can find the release as a binary here
We also created a branch that we will not make additions to any more but will definitively track to merge your contributions.

Device basics

Data format

ConnectTheDots is built on the assumption that data from sensors is sent to Azure IoT Hub in a prescribed JSON format. The minimum structure, with required attribute names, is

{
    "guid":	"string",
    "organization":	"string",
    "displayname": "string",
    "location": "string",
    "measurename": "string",
    "unitofmeasure": "string",
    "timecreated": "string",
    "value": double/float/integer
}

This should all be sent as one string message to IoT Hub, for example as the following strings:

{"guid":"62X74059-A444-4797-8A7E-526C3EF9D64B","organization":"My Org Name","displayname":"Sensor Name","location":"Sensor Location","measurename":"Temperature","unitofmeasure":"F","timecreated":"1975-09-16T12:00:00Z", "value":74}

or

{"guid":"62X74059-A444-4797-8A7E-526C3EF9D64B","organization":"my org name","displayname":"sensor name","location":"sensor location","measurename":"Temperature","unitofmeasure":"F","timecreated":"1975-09-16T12:00:00Z", "value":74.0001}

Furthermore, the project is built upon the assumption that the sensors create and format this JSON string.
For example, if using a sensor attached to an Arduino, the code running on the Arduino would send successive JSON strings, CRLF ended, out the serial port to a gateway such as a Raspberry Pi or Windows Tablet. The gateway does nothing other than receive the JSON string, package that into the right message format, adds the timecreated time stamp, and send it to Azure.

In the case of a directly connected device, the latest needs to send the JSON package to the IoT Hub leveraging one of the existing Azure IoT Hub device client SDKs.

All the device code included in this project, or submitted for inclusion, must conform to the JSON format requirement above.

Devices and Gateway

ConnectTheDots provides a Multi-protocol Gateway to collect data from devices that cannot, or should not, target the cloud directly. The Gateway code is tested on Mono for Linux and on the .NET Framework on Windows and is located in the source tree under Devices/Gateways/GatewayService, and is a simple system service.

To send data from a device to a gateway, you can just use the same exact data format and a device protocol adapter to implement any transport of your choice. The device protocol adapter is an assembly that implements the DeviceAdapterAbstract type to collect data from the device and enqueue them to the gateway for upload to the cloud. The Gateway automatically loads the device adapters from the Gateway binary directory, so deployment is extremely simple.
You can find some examples under Devices/Gateways/GatewayService/DeviceAdapters, and the matching devices under Devices/GatewayConnectedDevices.

We even have some devices running in separate processes as a Python script, sending data to an adapter Gateway on a socket or a serial port connection. It does not get any easier than that!

Software prerequisites

In order to reproduce one of the ConnectTheDots.io scenarios, you will need the following:

  1. Microsoft Azure subscription (free trial subscription is sufficient)
  2. [optional] Visual Studio 2013 or above – Community Edition is sufficient. Note that if you are not planning to use the Gateway nor making changes to the dashboard, you will NOT need Visual Studio.
  3. [optional] WiX Toolset — if you want to build installer of Gateway for Windows

Getting Started

To get started with ConnectTheDots, you will need to go through the following basic steps:

  1. Deploying services: this is easily done using the automated deployment script.
  2. Setup devices: follow these instructions to provision devices in the IoT Hub and modify and deploy code sample

Git hub connect the dots и windows iot

To explore the challenges of building an IoT application, we created a reference implementation called the Drone Delivery application.

Here is the scenario:

Fabrikam, Inc. runs a drone delivery service. The company manages a fleet of drone aircraft, and customers can request a drone to pick up goods for delivery. The drones send two types of telemetry:

  • Flight data: Latitude, longitude, altitude, velocity, and acceleration. Each drone sends this data once every 5 seconds.
  • Operating status: Engine temperature and battery level. Each drone sends this data once every 20 seconds.

We assume the drones support IP protocol and MQTT, and that the drones are are mostly-connected devices. That is, they send a constant stream of data while in flight, rather than batching data at intervals.

The following diagram shows the design of the application:

The architecture includes several data streaming paths that perform different functions:

Hot path. The hot path monitores the drones’ operating status to detect anomalies in the engine temperature. It uses Azure Stream Analytics to compute the average engine temperature of each drone over a 2-minute window. Anomolous readings are stored in Cosmos DB and also trigger an alert. The sample application includes stub code for the alerts. You could replace this with code to send an SMS message or a push notification to a mobile app.

Warm path. The warm path uses an Azure Function to write the latest position data for each drone to Cosmos DB. The data can then be queried using geo-spatial queries. For example, you can query for all drones within a given area.

Cold path. The cold path captures all of the raw telemetry and then processes it using HDInsight. The sample application includes a Hive query that summarizes the pickup and dropoff times for each delivery, based on the location data from the drones. You can then use Power BI to explore and visualize the results.

GitHub для пользователей Windows

Если ваш проект хранится только у вас на диске, то с поломкой диска вас ожидают неприятности. Даже регулярный бэкап не всегда сможет вас спасти.

Некоторые разработчики могут наворотить в проекте столько всего, что сами в шоке. А вспомнить, что и где делалось, затруднительно. Та еще неприятность.

Система контроля версий поможет вам избежать этих проблем. В случае необходимости можно совершить восстановление или откат изменений. Просмотреть и подтвердить или отменить правки. Ну а командная работа без системы контроля версий просто немыслима.

Если вы вдруг не знакомы, то я хочу немного познакомить вас с системой управления версиями по имени Git. Под катом вас ожидает описание того, как использовать GitHub вместе с Visual Studio.

Актуальное расширение называется GitHub Extension for Visual Studio. Оно подходит для Visual Studio 2015 и выше. Скачать vsix можно с github странички или с Visual Studio gallery.

Установить расширение можно и при установке Visual Studio:

Перед тем как продолжить, нужно выучить немного терминов. Если вы их знаете, то проматывайте вниз.

Push – отправка изменений из локального репозитория в удаленный репозиторий (в нашем случае он будет расположен на GitHub).

Fetch – получение изменений из удаленного репозитория для сравнения и возможного последующего слияния.

Merge – слияние. Применение изменений совершенных в другом репозитории текущим репозиторием. Что-то вроде объединения двух репозиториев.

Pull – комбинация fetching и merging. Сперва из удаленного репозитория получается список изменений, а затем изменения применяются к текущему репозиторию.

То есть, если кто-то кроме вас поработал и совершил изменения в репозитории GitHub, то вы можете последовательно совершить 2 действия: Fetch, а затем Merge. Или же вы можете сразу выполнить Pull. После этого в вашем локальном репозитории отобразятся совершенные изменения.

После установки GitHub Extension for Visual Studio, панель Team Explorer будет выглядеть так:

Если панель Team Explorer скрыта, то отобразить ее можно через меню «View» / «Вид». Подключившись к GitHub (нажав Connect… и введя логин с паролем) получим возможность склонировать репозиторий GitHub или создать новый (кнопочки Clone и Create):

При клонировании будут выведен список репозиториев к которым у вас есть доступ:

При создании репозитория, вы сможете ввести его название, описание и выбрать лицензию, в соответствии с которой разрешено использование кода:

В данном случае Git ignore содержит предустановки для проектов различного типа. А так этот файлик формата .gitignore предназначен для того, чтобы указать в нем какие директории и файлы требуется исключить из системы управления версиями.

На случай, если вы хотите очень хорошо спрятать от посторонних глаз котлету репозиторий, то вы можете пометить его как Private. Но для этого нужна платная подписка.

Для студентов GitHub предлагает специальное предложение — Student Developer Pack, которое в частности включает в себя бесплатное неограниченное количество приватных репозиториев.

После создания репозитория необходимо создать проект. Лично я предпочитаю наоборот, сначала создать проект и только затем его добавить в Git. Можно при создании проекта создать и репозиторий Git. Для этого достаточно поставить галочку.

Если эту галочку при создании проекта не поставить, а просто открыть проект в VS, то в меню Файл станет доступен пункт «Add to Source Control» / «Добавить в систему управления версиями»

После его нажатия, проект будет добавлен в систему управления версиями Git, и внутри папки с проектом будет создана локальная папка .git. В Team Explorer это будет выглядеть так:

Переключившись между Team Explorer и Solution Explorer можем совершить какие-то изменения в проекте. После любых изменений можно совершить коммит — своеобразную точку восстановления. Для этого вернемся в Team Explorer, в меню которого имеется кнопка с нарисованным на ней домиком. Нажатие на нее приведет вас в главное меню:

Кнопка «Changes» / «Изменения» позволит зафиксировать изменения (при этом обязательно необходимо указать комментарий с описанием изменений). Но все действия пока что будут совершены только с локальным репозиторием git.

При создании проекта иногда создается так называемый «Initial commit», в котором пишется что-то вроде «Проект был создан за три дня». Если вы только что создали проект, то изменений в нем пока что еще нет. А если изменений нет, то коммит создать не получится. Я добавлял строку с текстом, поэтому в комментарии постарался описать это коротко, но понятно:

Можно просмотреть совершенные изменения. Для этого на интересующем нас файле нужно вызвать контекстное меню и выбрать «Compare with Unmodified. » / «Сравнить с неизмененной…»

Получим примерно такое вот сравнение:

В данном случае было добавлено всего 2 строки кода. Через то же самое контекстное меню все изменения, произошедшие со времени последнего коммита можно отменить. Очень удобная фича.

Теперь, давайте, опять перейдем в главное меню, нажав домик. Для того чтобы отправить изменения на GitHub необходимо нажать кнопку «Sync» / «Синхронизация».

Так как наш проект еще не был опубликован на GitHub, то нам предложат это сделать:

Кстати, .git вполне можно опубликовать не только на GitHub, но и на Visual Studio Team Services.

Если мы публиковали проект ранее, то в списке исходящих фиксаций будет расположен наш коммит:

Нажатие Push приведет к отправке изменений в репозиторий, расположенный на сервере GitHub.

Совершив для пробы некоторые изменения прямо через браузер в репозитории, расположенном на GitHub (да, так тоже можно), я снова зашел в синхронизацию и нажал Fetch:

Здесь двойным кликом можно открыть информацию о коммите:

И кликнув уже на файл просмотреть изменения:

В том же самом окне синхронизации можно просмотреть историю:

Историю можно просматривать в простом представлении и в подробном:

Теперь, давайте представим, что мы работаем в команде и кто-то другой уже совершил какие-то изменения в своем локальном репозитории и отправил из в GitHub. И вы тоже совершили изменения в том же самом файле и в той же самой строке. В таком случае при синхронизации с GitHub у вас возникнет конфликт:

Кликнув на Conflicts получим такое вот окошко в котором после клика на файле откроется меню с кнопкой Merge:

Теперь мы может ставя галочки выбрать изменения, которые мы хотим оставить в окончательной версии. Окончательная версия на следующем скриншоте отображена внизу. Код в ней тоже можно править:

После внесения изменения нужно нажать Accept Merge (в верхнем левом углу), после чего сделать коммит:

Страничка самого расширения на GitHub: github.com/github/visualstudio

Github Desktop и PowerShell environment for Git

Github Desktop — утилита совершенно независимая и с Visual Studio никак не связанная. Скачать можно здесь.

Утилита доступна для пользователей Mac и Windows. Вместе с ней устанавливается и командная строка Git Shell. Фактически это PowerShell с набором скриптов для интеграции с Git. Называется PowerShell environment for Git. Сокращенно posh-git.

На GitHub страничке проекта posh-git можно найти краткую инструкцию о том, как установить командную строку posh для git вручную.

Интерфейс самой утилиты и работу с ней я рассматривать не буду. Думаю, что он не сложный и с ним вы сможете разобраться сами. Давайте лучше немного поиграем с командной строкой. В отличие от GUI командная строка, как правило, предоставляет гораздо больше возможностей. Но мы рассмотрим только основные команды.

Чтобы просмотреть текущую конфигурацию и убедится, что Git присутствует, можно выполнить команду:

Для того чтобы склонировать репозиторий достаточно выполнить команду git clone. Например:

После выполнения этой команды, в текущей директории появится папка с проектом. Кроме http:// и https:// поддерживаются и протоколы SSH и git://. Если перейти в папку с проектом с помощью команды cd (в случае примера cd BarcodeScanner), то командная строка преобразится:

git, что обозначает, что вы попали в среду PowerShell для Git. Можно выполнить команду git status, чтобы узнать, не требуется ли синхронизировать локальный репозиторий. Ответ может быть таким:

Самые популярные команды это те, которые мы уже рассматривали в рамках интерфейса расширения VS: git fetch, git merge, git push. Если вы зайдете в директорию (наименование PortableGit_xxx директории, я так полагаю, может быть несколько иным):

то вы обнаружите в ней множество исполняемых файлов, которые эмулируют команды. Как уже было сказано, справкой git можно пользоваться, но, давайте опробуем несколько команд для примера.

Например, если в директории проекта появится новый файл, то команда git status выдаст:

А значит добавить файл нужно командой git add index.html. Теперь изменения нужно подтвердить с помощью git commit. Эта команда откроет текстовый редактор, который установлен по умолчанию. В нем необходимо в первую строку ввести текст, описывающий совершенные изменения. Если начать строку с символа #, то это будет комментарий. Комментарии можно оставить в строках ниже. Если не оставить никакого текста с описанием коммита, то коммит не произойдет. Можно указать текст коммита сразу в коммандной строке с помощью параметра –m. Например: git commit –m «File index.html added»

Теперь можно с помощью git push отправить изменения в GitHub репозиторий. Если это ваш репозиторий. Чужой репозиторий вы можете скопировать к себе, создав развилку/копию репозитория — Fork. Сделав какие-то изменения, вы сможете предложить их автору оригинального репозитория создав pull request.

На этом позвольте завершить описание возможностей работы с GitHub для пользователей Windows. Если хотите продолжить изучение, то на MVA вы можете посмотреть курс GitHub for Windows Users

Git Guides

Git hub connect the dots и windows iot

Everything you need to know about Git, from getting started to advanced commands and workflows.

Whether or not you’ve worked with version control before, there are a few things you should know before getting started with Git:

Like we mentioned above, Git uses SHA compression, which makes it very fast.

Git can handle merge conflicts, which mean that it’s OK for multiple people to work on the same file at the same time. This opens up the world of development in a way that isn’t possible with centralized version control. You have access to the entire project, and if you’re working on a branch, you can do whatever you need to and know that your changes are safe.

Speaking of branches, Git offers a lot of flexibility and opportunity for collaboration with branches. By using branches, developers can make changes in a safe sandbox.

Instead of only committing code that is 100% sure to succeed, developers can commit code that might still need help. Then, they can push that code to the remote and get fast feedback from integrated tests or peer review.

Without sharing the code through branches, this would never be possible.

If you make a mistake, it’s OK! Commits are immutable, meaning they can’t be changed. (Note: You can change history, but it will create new replacement commits instead of editing the existing commits. More on that later!) This means that if you do make a mistake, even on an important branch like master, it’s OK. You can easily revert that change, or roll back the branch pointer to the commit where everything was fine.

The benefits of this can’t be overstated. Not only does it create a safer environment for the project and code, but it fosters a development environment where developers can be braver, trusting that Git has their back.

Getting Started With Git

Depending on your operating system, you may already have Git installed. But, getting started means more than having the software! To get started, it’s important to know the basics of how Git works. You may choose to do the actual work within a terminal, an app like GitHub Desktop, or through GitHub.com. (Note: while you can interact with Git through GitHub.com, your experience may be limited. Many local tools can give you access to the most widely used Git functionalities, though only the terminal will give you access to them all.)

There are many ways to use Git, which doesn’t necessarily make it easier! But, the fundamental Git workflow has a few main steps. You can practice all of these in the Introduction to GitHub Learning Lab course.

Make change (and make a commit)

Once you’ve created a branch, and moved the HEAD pointer to it by «checking out» to that branch, you’re ready to get to work. Make the changes in your repository using your favorite text editor or IDE.

Next, save your changes. You’re ready to start the commit!

Push your changes to the remote

By default, git push only pushes the branch that you’re currently checked out to.

Sometimes, if there has been a new commit on the branch on the remote, you may be blocked from pushing. Don’t worry! Start with a simple git pull to incorporate the changes on the remote into your own local branch, resolve any conflicts or finish the merge from the remote into the local branch, and then try the push again.

Open a pull request

Pull requests are the powerhouse of GitHub. Integrated tests can automatically run on pull requests, giving you immediate feedback on your code. Peers can give detailed code reviews, letting you know if there are changes to make, or if it’s ready to go.

Make sure you start your pull requests off with the right information. Put yourself in the shoes of your teammates, or even of your future self. Include information about what this change relates to, what prompted it, what is already done, what is left to do, and any specific asks for help or reviews. Include links to relevant work or conversations. Pull request templates can help make this process easy by automating the starting content of the body of pull requests.

Collaborate (get feedback from tests or peers, make more commits locally and then push them up and get more feedback)

Once the pull request is open, then the real fun starts. It’s important to recognize that pull requests aren’t meant to be open when work is finished. Pull requests should be open when work is beginning! The earlier you open a pull request, the more visibility the entire team has to the work that you’re doing. When you’re ready for feedback, you can get it by integrating tests or requesting reviews from teammates.

It’s very likely that you will want to make more changes to your work. That’s great! To do that, make more commits on the same branch. Once the new commits are present on the remote, the pull request will update and show the most recent version of your work.

Once you and your team decide that the pull request looks good, you can merge it. By merging, you integrate the feature branch into the other branch (most typically the master branch). Then, master will be updated with your changes, and your pull request will be closed. Don’t forget to delete your branch! You won’t need it anymore. Remember, branches are lightweight and cheap, and you should create a new one when you need it based on the most recent commit on the master branch.

If you choose not to merge the pull request, you can also close pull requests with unmerged changes.

Learning & Mastering Git Commands

If you’re getting started with Git, a great place to start is the Git Cheat sheet. It’s translated into many languages, open source as a part of the github/training-kit repository, and a great starting place for the fundamentals on the command line.

Some of the most important and most used commands that you’ll find there are:

Getting Started With GitHub

If you’re wondering where Git ends and GitHub begins, you’re not alone. They are tied closely together to make working with them both a seamless experience. While Git takes care of the underlying version control, GitHub is the collaboration platform built on top of it. GitHub is the place for pull requests, comments, reviews, integrated tests, and so much more. Most developers work locally to develop, and use GitHub for collaboration. That ranges from using GitHub to host the shared remote repository, to working with colleagues and capitalizing on features like protected branches, code review, GitHub Actions, and more.

The best place to practice using Git and GitHub is the Introduction to GitHub Learning Lab course.

Set up Git

At the heart of GitHub is an open source version control system (VCS) called Git. Git is responsible for everything GitHub-related that happens locally on your computer.

To use Git on the command line, you’ll need to download, install, and configure Git on your computer. You can also install GitHub CLI to use GitHub from the command line. For more information, see «About GitHub CLI.»

If you want to work with Git locally, but don’t want to use the command line, you can instead download and install the GitHub Desktop client. For more information, see «Installing and configuring GitHub Desktop.»

If you don’t need to work with files locally, GitHub lets you complete many Git-related actions directly in the browser, including:

Next steps: Authenticating with GitHub from Git

When you connect to a GitHub repository from Git, you’ll need to authenticate with GitHub using either HTTPS or SSH.

Connecting over HTTPS (recommended)

Connecting over SSH

If you clone with SSH, you must generate SSH keys on each computer you use to push or pull from GitHub.

Congratulations, you now have Git and GitHub all set up! You may now choose to create a repository where you can put your projects. This is a great way to back up your code and makes it easy to share the code around the world. For more information see «Create a repository».

You can create a copy of a repository by forking it and propose the changes that you want to see without affecting the upstream repository. For more information see «Fork a repository.»

Each repository on GitHub is owned by a person or an organization. You can interact with the people, repositories, and organizations by connecting and following them on GitHub. For more information see «Be social.»

GitHub has a great support community where you can ask for help and talk to people from around the world. Join the conversation on Github Support Community.

Git Guides

Everything you need to know about Git, from getting started to advanced commands and workflows.

Whether or not you’ve worked with version control before, there are a few things you should know before getting started with Git:

Like we mentioned above, Git uses SHA compression, which makes it very fast.

Git can handle merge conflicts, which mean that it’s OK for multiple people to work on the same file at the same time. This opens up the world of development in a way that isn’t possible with centralized version control. You have access to the entire project, and if you’re working on a branch, you can do whatever you need to and know that your changes are safe.

Speaking of branches, Git offers a lot of flexibility and opportunity for collaboration with branches. By using branches, developers can make changes in a safe sandbox.

Instead of only committing code that is 100% sure to succeed, developers can commit code that might still need help. Then, they can push that code to the remote and get fast feedback from integrated tests or peer review.

Without sharing the code through branches, this would never be possible.

If you make a mistake, it’s OK! Commits are immutable, meaning they can’t be changed. (Note: You can change history, but it will create new replacement commits instead of editing the existing commits. More on that later!) This means that if you do make a mistake, even on an important branch like master, it’s OK. You can easily revert that change, or roll back the branch pointer to the commit where everything was fine.

The benefits of this can’t be overstated. Not only does it create a safer environment for the project and code, but it fosters a development environment where developers can be braver, trusting that Git has their back.
