Ni myrio программирование labview

Если вы всё же решились заняться разработкой робота для компетенции «Мобильная робототехника» WSR и у вас уже есть робототехнический конструктор от Studica, то традиционно вторым вопросом будет: «Ну вот, железку я собрал, как теперь заставить ЭТО двигаться?»
Попробуем решить эту задачу.

Основной программируемый модуль, допустимый к использованию при создании роботов в соответствии с заданием тестового проекта компетенции «Мобильная робототехника» WorldSkills в 2016-2017 годах — это многоцелевой блок управления myRIO от компании National Instruments. Традиционно, для его программирования используется среда разработки LabView той же компании, но с установленным дополнительным модулем LabView for myRIO.
Рекомендуем вам также установить модули для работы с техническим зрением. Они понадобятся позднее.

Установке программного обеспечения, подключению и настройке myRIO будет посвящена отдельная статья. А сейчас будем считать, что всё уже готово.
Итак, для выполнения следующих заданий необходимо иметь:

• Ноутбук или настольный компьютер с программным обеспечением LabView;
• Модуль myRIO с блоком питания или подключённым к аккумуляторной батарее;
• Активированное соединение компьютера с модулем myRIO по USB-кабелю или WiFi;
• Плату драйвера моторов (NI зовёт их адаптерами) Digilent Motor Adapter (аналог от Studica будет рассмотрен отдельно);
• Батарею для питания моторов, лучше не ту, что питает сам myRIO;
• Пару DC-моторов (ходовых) Tetrix или близких по характеристикам.

Подключаем моторы согласно схеме на рисунке:

Надеюсь, что с подключением батареи к клеммам платы драйвера проблем не возникло (на схеме не указано как это сделать). Затем вставляем платы в подходящие разъемы MXP myRIO.
Неплохой идеей является установка на оси моторов колёс с нанесенными на них отметками положения. Например, можно наклеить цветную изоленту на один из роликов onmi-колеса.
ВНИМАНИЕ!
Крайне желательно перед продолжением закрепить моторы или, если они уже установлены на робота, вывесить колёса, установив робота на подставку!

Начинаем программировать!
Открываем LabView и создаем новый проект для myRIO.

Refer to the LabVIEW Readme for additional system requirements and supported operating systems for LabVIEW 2021.

• The myRIO Toolkit is compatible with only 32-bit LabVIEW. Install 32-bit LabVIEW even if you use a 64-bit operating system.
• You might need more memory than the LabVIEW-recommended minimum depending on the size of the application you design in LabVIEW on the host computer.

Supported Operating Systems

LabVIEW 2021 myRIO Toolkit supports the following operating systems:

• Windows 10
• Windows Server 2022
• Windows Server 2019
• Windows Server 2016

Note Refer to Unsupported Windows Operating Systems for more information about support for Microsoft Windows OSes.

Installation Instructions

Download the LabVIEW myRIO Toolkit installer from ni.com/downloads. NI software includes NI Package Manager to handle the installation. Refer to the NI Package Manager Manual for more information about installing, removing, and upgrading NI software using Package Manager.

• If Windows Update is enabled, the installation process might hang if Windows Update interferes with the installation of Microsoft Visual C++ 2015 Run-Time. Visit ni.com/r/exjq43 for more information and steps to resolve this issue.

Installing the High Throughput Add-On for myRIO

The High Throughput Add-On for myRIO provides the High Throughput FPGA Personality VIs which support high-speed analog or digital data access. The High Throughput FPGA Personality VIs appear on the myRIO palette only after you install the High Throughput Add-On for myRIO.

Visit ni.com/info and enter the Info Code ex6g5a to download the High Throughput Add-On for myRIO installer. Double-click the setup.exe file in the root directory of the installer and follow the instructions on the screen to install this product.

Product Security and Critical Updates

Visit ni.com/security to view and subscribe to receive security notifications about NI products. For information about critical updates from NI, refer to Available Critical and Security Updates for NI Software.

Accessing the LabVIEW for myRIO Environment

The myRIO Toolkit provides the LabVIEW for myRIO environment to allow you to easily access myRIO-specific features and focus on developing myRIO applications.

You can use the Choose Environment Settings dialog box to change your LabVIEW environment. To display this dialog box, select Tools»Choose Environment from LabVIEW.

Accessing the Documentation

Refer to the LabVIEW Help, accessible by selecting Help»LabVIEW Help from LabVIEW, for information about the myRIO Toolkit.

Finding Examples

Select Help»Find Examples from LabVIEW to launch the NI Example Finder. LabVIEW examples for the myRIO Toolkit are located in the labview\examples\myRIO directory. You can modify an example VI to fit an application, or you can copy and paste from one or more examples into a VI that you create.

Automating the Installation of NI Products

You can automate the installation of most NI products using command-line arguments to suppress some or all of the installer user interface and dialog boxes.

If the NI product you are installing uses Microsoft .NET 4.6.2, the .NET installer may run before any NI software installs and may require a reboot before the installation of NI software begins. To avoid a .NET reboot, install .NET 4.6.2 separately before you install NI software.

For more information about automating the installation of NI products, refer to Automating an Installer in the NI Package Manager manual.

Using NI Software with Microsoft Windows 10

For more information about NI support for Windows 10, refer to NI Product Compatibility for Microsoft Windows 10.

Unsupported Windows Operating Systems

LabVIEW myRIO Toolkit no longer supports Windows Vista/XP/7/8.x, Windows Server 2003/2008/2012, or any 32-bit Windows operating system. Versions of this product that ship after May 1, 2021, may not install or execute correctly on these operating systems.

  Activating your NI myRIO Software

  Your myRIO hardware may have included a software serial number that can be used to activate both the required and optional software. This serial number would be located on the software DVD packaging. If not, you can activate the software using your school’s Academic Volume License, or by purchasing individual licenses.

  LabVIEW Programming for myRIO

  After installing the required software for myRIO, start by following a customized getting started experience designed to ensure your success with NI myRIO and access to NI myRIO resources directly from the LabVIEW Getting Started Window.

  After completing the Getting Starting Wizard, you can write programs quickly using I/O-specific Express VIs directly from the LabVIEW pallette.

  When you are ready to graduate to the next level of programming, click the “View Code” tab on any Express VI to see the underlying code.

  Additionally, you can click the Connection Diagram tab to help you wire to the I/O type you have chosen on the myRIO.

  You can program with NI myRIO Low Level VIs to learn more about the open, read/write, close architecture, which is common to LabVIEW programming.

  To customize the FPGA of NI myRIO, you must use the LabVIEW FPGA Module. This gives you the ability to view the NI myRIO FPGA shipping personality as well as make customizations to the FPGA.

  C Support for NI myRIO

  You can program the NI myRIO processor using C or C++. It is important to note that you must use the LabVIEW FPGA Module to customize the FPGA. Learn more about C programming with NI myRIO and how to get started.
