Использование среды разработки IAR Ebedded Workbench IDE

Введение

Используя разные микроконтроллеры, возникает необходимость выбрать удобную среду разработки. Нам есть из чего выбирать – будь то IAR или Keil µVision, или, даже Code Composer Studio.
Ниже пойдет речь об IAR Embedded Workbench IDE на примере STM32F10x. Эта среда разработки достаточно мощная. Имеются всякие вкусняшки.

Настройка IAR

В первую очередь нужно настроить IAR.

Основные настройки
Настройки проекта

Допустим, создавать новый проект мы умеем (если нет, то Project->Create New Project…). После создания проекта нам доступны две конфигурации проекта – Debug и Release. Переключаться между ними можно в окне Workspace:

Рис. 1 – Окно Workspace

Удобно использовать несколько конфигураций. В конфигурации Debug можно выбрать симулятор программатора, а в Release – конкретный программатор (к примеру, J-Link). Что позволит сначала отлаживать в симуляторе, не теряя время на прошивку микроконтроллера, а потом уже прошивать под конфигурацией Release.
Добавлять новые конфигурации можно через меню: Project->Edit Configurations.
Опции самого проекта – Project->Options… (Alt+F7). Для открытия окна опций проекта нужно выделить сам проект в окне Workspace, иначе откроются опции того файла, который был выделен.
Настройки буду приводить для конфигурации Debug (в скобках – для Release).
Открываем опции (Alt+F7)

  1. General Options.
    Вкладка Target. Выбираем Device – например, ST STM32F100xB (у меня STM32VLDISCOVERY с STM32F100RBT6 на борту).
  2. С/C++ Compiler.
    Вкладка Optimizations. Выбираем LevelNone (для ReleaseHigh).
    Вкладка Preprocessor. В поле Additional include directories вводим все пути заголовочных файлов, имеющих расширение *.h. Например:
    $PROJ_DIR$\..\Lib\include\
    Остальные переменные, на подобии $PROJ_DIR$, можете посмотреть в хелпе по F1, введя в поиске Argument variables.
    В этой же вкладке, в поле Defined symbols вписываем нужные дефайны. Это аналог обычной директивы #define. Для нашей отладочной платки нужно ввести STM32F10X_MD_VL, если мы хотим использовать библиотеки от криворуких STM’овцев.
    Так же для конфигурации Debug можно завести дефайн DEBUG. Это удобно, если использовать, к примеру, конструкцию:
    #ifndef DEBUG
    Delay(100 часов);
    #endif
    Зачем же нам ждать это время при отладке, правда же?
  3. Linker.
    Вкладка Config. Здесь можно выбрать конфигурационный файл для линковщика, если это необходимо (если у вас не 8-ми битный микроконтроллер). Если необходимо перераспределить память микроконтроллера по-своему, то нужно ковырять файл *.icf. Об этом можно прочитать в Help->C/C++ Development Guide страница 81 Linking your application. Если эта тема сложная, то можно написать об этом отдельно. Спрашивайте, если что.
  4. Debugger.
    Вкладка Setup. В поле Driver выбираем Simulator (для Release – свой программатор. Для моей платы – ST-LINK. В настройках для него нужно выбрать интерфейс SWD).

    Рис. 2 – Дерево проекта

И, напоследок, создайте дерево проекта на ваш вкус.

Некоторые приемы

Горячие клавиши
Поиск:

Обычный поиск – Ctrl+F
Найти дальше – F3
Поиск по файлам проекта – Ctrl+Shift+F
Шагать по найденному (или по ошибкам/ворнингам) – F4

Навигация по проекту:

Перейти к объявлению переменной (даже, если она в другом файле) – F12 — очень полезная функция!
Навигация вперед – Alt+Right
Навигация назад – Alt+Left

Разное:

Открыть header/source – Ctrl+Shift+H (или П.К.М в редакторе, и в контекстном меню выбрать Open Header/Source File)
Закомментировать выделенный блок – Ctrl+K
Разкомментировать – Ctrl+Shift+K
Выделить содержимое скобок – Ctrl+B
Автовыравнивание – Ctrl+T
Поставить/убрать Breakpoint – F9
Вставить шаблон – Ctrl+Shift+Space – тоже интересная штука.

Чтобы добавить свой шаблон, нужно открыть файл CodeTemplates.ENU.txt через меню Edit->Code Templates->Edit Templates
Теперь можно ввести примерно следующее:

#TEMPLATE ,[=default value], .

Знак «&» нужен для быстрого доступа (буква будет подчеркнута). Можно использовать знак «>» для создания подменю. Все интуитивно понятно.

Сохраним файл и вызовем Template menu (Ctrl+Shift+Space). В нем выберем Warning:

Рис. 3 – Вызов меню Template

Введем необходимый текст:

Рис. 4 – Шаблон Warning

Жмякаем по кнопке OK. В результате, появится строчка:

Рис. 5 – Результат использования шаблона

При компиляции все ворнинги и ерроры (#error ) будут выводиться в окне Build.

Заключение

В этой статье были приведены основные возможности IAR, позволяющие достаточно быстро ориентироваться в проекте. Рекомендую использовать горячие клавиши. Это значительно сокращает время работы над проектом.
Буду признателен, если читатель дополнит или поправит меня.

Как установить IAR Embedded Workbench в ubuntu [duplicate]

Можно ли установить файлы .exe и .msi (программное обеспечение Windows) в Ubuntu?

30 ответов

Помимо реализации WINE, если у вас есть копия окон, вы можете также взглянуть на VirtualBox или другую технологию виртуализации.

Вот ссылка на настройку: http : //www.ubuntugeek.com/create-and-manage-virtual-machines-using-virtualbox.html

Конс с использованием виртуальной машины (виртуальной машины) состоит в том, что они обычно зарезервированы для верхнего конца машины, поскольку они являются ОС внутри вашей ОС, которые занимают дополнительные ресурсы ОС.

pro будет заключаться в том, что их проще резервировать и восстанавливать в случае катастрофического сбоя программного обеспечения.

В Википедии есть статья о VirtualBox и виртуализации. Я могу опубликовать только одну ссылку, пока не получу более интересные моменты, поэтому я решил, что учебник станет лучшей ссылкой, поскольку в нем есть краткое описание

Вы должны знать, что Ubuntu — это совершенно другая ОС для Windows. Структуры файлов несовместимы. Поэтому файлы .exe предназначены для Windows, а не для Linux. Поэтому они не будут работать.

Сказав это, есть некоторые файлы .exe, которые хорошо работают в Linux (Ubuntu) через программу под названием wine. Последняя стабильная версия должна быть в программном центре.

Моя самая сильная рекомендация — перед установкой wine — перейти на сайт разработчиков и ознакомиться с тем, что он может и чего не может сделать, и какие программы окон, как известно, работают с ним.

Наконец, есть 1000 приложений, предназначенных для Linux, которые делают то же самое, что делают приложения Windows. Многие из них являются кросс-платформенными, такими как VLC, Firefox, чтобы назвать пару.

Кроме того, если вы хотите получать обновления от разработчиков Wine, чтобы все больше и больше программного обеспечения Windows поддерживалось, перейдите в System-> Software Sources и перейдите на другую вкладку Software. Нажмите кнопку «Добавить» и скопируйте + вставьте в нее: ppa: ubuntu-wine / ppa

Файл windows windows exe не запускается на linux, это разная порода операционной системы. Вы можете установить вино, а затем повторите попытку. Хорошо работает в большинстве случаев.

И дайте ubuntu справедливый шанс, вам не нужна Windows в большинстве случаев. Вы просто под впечатлением, что это является необходимой частью компьютерного опыта.

Как мне установить вино?

Да, как говорили другие, вы можете использовать вино для запуска программ Windows.

Как только вино установлено, вы можете запустить исполняемый файл Windows, щелкнув его правой кнопкой мыши и нажав «открыть с вином загрузчик программ Windows» ‘или используя терминал, как описано выше.

Здесь вы должны проверить, можно ли запустить программу в вине. Многие программы не будут работать отлично или потребуется дополнительная настройка для запуска. Программа, называемая winetricks (см. Http://wiki.winehq.org/winetricks), может сделать вещи немного проще.

Всегда старайтесь использовать собственное программное обеспечение или бесплатные альтернативы, если это возможно. Вы можете искать приложения в Ubuntu Software Center — программы здесь будут работать намного лучше и не нуждаются в небольшой конфигурации. Вы также можете посмотреть на этом сайте: здесь для бесплатных программных альтернатив запатентованным продуктам.

Specific documentation for C-SPY debugger drivers

Documentation for Realtime Operating System support

CMSIS compliance

IAR Embedded Workbench is compliant with Arm Cortex Microcontroller Software Interface Standard (CMSIS).

What is CMSIS?

The Arm Cortex Microcontroller Software Interface Standard (CMSIS) provides a single, scalable interface standard across all Cortex-M series processor vendors which enables easier code re-use and sharing across software projects to reduce time-to-market for new embedded applications.

The CMSIS has been developed by Arm in close partnership with several key silicon and software vendors including Atmel, IAR Systems, Micrium, NXP, SEGGER, STMicroelectronics and Texas Instruments, and provides a common approach to interface to peripherals, real-time operating systems, and middleware components.

The standard has been designed to be fully scalable to ensure that it is suitable for all Cortex-M processor series microcontrollers from the smallest 8KB device up to devices with sophisticated communication peripherals such as Ethernet or USB-OTG. (The CMSIS memory requirement for the Core Peripheral Access Layer is less than 1KB code, less than 10 bytes RAM.)

Arm provides as part of the CMSIS the following software layers that are available for various compiler implementations:

  • Core Peripheral Access Layer: contains name definitions, address definitions and helper functions to access core registers and peripherals. It defines also an device independent interface for RTOS Kernels that includes debug channel definitions.
  • Middleware Access Layer: provides common methods to access peripherals for the software industry. The Middleware Access Layer is adapted by the Silicon Vendor for the device specific peripherals used by middleware components.

These software layers are expanded by Silicon partners with:

  • Device Peripheral Access Layer: provides definitions for all device peripherals
  • Access Functions for Peripherals (optional): provides additional helper functions for peripherals

CMSIS-DAP

CMSIS-DAP is the interface firmware for a debug probe that translates USB packets to the Arm core SWD or JTAG protocol. This allows the C-SPY Debugger, with the addition of just a USB cable, to connect to any development board implementing the CMSIS-DAP connection.

CMSIS-NN

CMSIS version 5.3 adds the CMSIS-NN software library, a collection of efficient neural network kernels developed to maximize the performance and minimize the memory footprint of neural networks on Cortex-M processor cores.

Languages and standards

The IAR C/C++ compilers offer different dialects of the C and C++ programming languages, as well as different extensions specific for embedded programming (please note that not all language standards are supported for all target implementations). The compiler can be instructed to disable extensions for strict conformance to the standards.

A wide range of industry-standard debug and image formats compatible with most popular debuggers and emulators are supported. This includes ELF/DWARF where applicable.

ISO/ANSI C/C++ Compliance

The IAR C/C++ compilers adhere to a freestanding implementation of the following C programming language standards:

  • INCITS/ISO/IEC 9899:2018, known as C18 (Latest version only).
  • The compiler supports all C++17 features. The C++ library supports C++14 with no C++17 additions. (Latest version only).
  • ISO/IEC 14882:2015, known as C++14
  • INCITS/ISO/IEC 9899:2012, known as C11
  • ANSI X3.159-1989, known as C89

The ISO/ANSI C/C++ Compliance level varies between the different compilers. For complete information, please refer to the IAR C/C++ Compiler user documentation in your chosen product.

IEEE 754 standard

IAR Embedded Workbench supports the IEEE 754 standard for floating-point arithmetic.

MISRA C

MISRA C is a software development standard for the C programming language developed by MISRA, The Motor Industry Software Reliability Association. Its aims are to facilitate code safety, portability and reliability in the context of embedded systems, specifically those systems programmed in ISO C.

The first edition of the MISRA C standard, «Guidelines for the use of the C language in vehicle based software», was produced in 1998. In 2004, a second edition was produced with many substantial changes to the guidelines, including a complete renumbering of the rules. Additionally MISRA C:2012 with extended support and MISRA C++:2008 for identifying unsafe code constructs in the C++ standard have also been added to the standards.

IAR Embedded Workbench features an add-on product C-STAT so you can check compliance with rules as defined by MISRA C:2004, MISRA C++:2008 and MISRA C:2012.

Test validation

We use the following commercial test suites to test conformance of our tools to the standards:

  • Plum Hall Validation test suite for ISO/IEC C conformance
  • Perennial EC++ Validation Suite for C++ conformance
  • Dinkum C++ Proofer to test how our libraries conform to the C and C++ standard as well as test our STL implementation against the C++ standard.

In addition to the commercial suites, we use several in-house test suites for testing new features, regression testing, corrected errors, etc.
