*********************************************** Standard Setup of Toolchain for Windows *********************************************** :link_to_translation:`zh_CN:[中文]` Introduction ============ ESP-IDF requires some prerequisite tools to be installed so you can build firmware for supported chips. The prerequisite tools include Python, Git, cross-compilers, CMake and Ninja build tools. For this Getting Started we are going to use the Command Prompt, but after ESP-IDF is installed you can use `Eclipse Plugin `_ or another graphical IDE with CMake support instead. .. note:: Limitations: - The installation path of ESP-IDF and ESP-IDF Tools must not be longer than 90 characters. Too long installation paths might result in a failed build. - The installation path of Python or ESP-IDF must not contain white spaces or parentheses. - The installation path of Python or ESP-IDF should not contain special characters (non-ASCII) unless the operating system is configured with "Unicode UTF-8" support. System Administrator can enable the support via ``Control Panel`` > Change ``date``, ``time``, or ``number`` formats > ``Administrative tab`` > Change ``system locale`` > check the option ``Beta: Use Unicode UTF-8 for worldwide language support`` > ``Ok`` > reboot the computer. .. _get-started-windows-tools-installer: ESP-IDF Tools Installer ======================= The easiest way to install ESP-IDF's prerequisites is to download one of ESP-IDF Tools Installers. +-------------------+--------------------------------+ | |download-logo| | `Windows Installer Download`_ | +-------------------+--------------------------------+ .. |download-logo| image:: ../../_static/logo_windows_install.png :target: https://dl.espressif.com/dl/esp-idf/?idf=4.4 .. _Windows Installer Download: https://dl.espressif.com/dl/esp-idf/?idf=4.4 What Is the Usecase for Online and Offline Installer ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Online Installer is very small and allows the installation of all available releases of ESP-IDF. The installer downloads only necessary dependencies including `Git For Windows`_ during the installation process. The installer stores downloaded files in the cache directory ``%userprofile%\.espressif`` Offline Installer does not require any network connection. The installer contains all required dependencies including `Git For Windows`_ . Components of the Installation ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The installer deploys the following components: - Embedded Python - Cross-compilers - OpenOCD - CMake_ and Ninja_ build tools - ESP-IDF The installer also allows reusing the existing directory with ESP-IDF. The recommended directory is ``%userprofile%\Desktop\esp-idf`` where ``%userprofile%`` is your home directory. Launching ESP-IDF Environment ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ At the end of the installation process you can check out option ``Run ESP-IDF PowerShell Environment`` or ``Run ESP-IDF Command Prompt (cmd.exe)``. The installer launches ESP-IDF environment in selected prompt. ``Run ESP-IDF PowerShell Environment``: .. figure:: ../../_static/esp-idf-installer-screenshot-powershell.png :align: center :alt: Completing the ESP-IDF Tools Setup Wizard with Run ESP-IDF PowerShell Environment :figclass: align-center Completing the ESP-IDF Tools Setup Wizard with Run ESP-IDF PowerShell Environment .. figure:: ../../_static/esp-idf-installer-powershell.png :align: center :alt: ESP-IDF PowerShell :figclass: align-center ESP-IDF PowerShell ``Run ESP-IDF Command Prompt (cmd.exe)``: .. figure:: ../../_static/esp-idf-installer-screenshot.png :align: center :alt: Completing the ESP-IDF Tools Setup Wizard with Run ESP-IDF Command Prompt (cmd.exe) :figclass: align-center Completing the ESP-IDF Tools Setup Wizard with Run ESP-IDF Command Prompt (cmd.exe) .. figure:: ../../_static/esp-idf-installer-command-prompt.png :align: center :alt: ESP-IDF Command Prompt :figclass: align-center ESP-IDF Command Prompt Using the Command Prompt ======================== For the remaining Getting Started steps, we are going to use the Windows Command Prompt. ESP-IDF Tools Installer also creates a shortcut in the Start menu to launch the ESP-IDF Command Prompt. This shortcut launches the Command Prompt (cmd.exe) and runs ``export.bat`` script to set up the environment variables (``PATH``, ``IDF_PATH`` and others). Inside this command prompt, all the installed tools are available. Note that this shortcut is specific to the ESP-IDF directory selected in the ESP-IDF Tools Installer. If you have multiple ESP-IDF directories on the computer (for example, to work with different versions of ESP-IDF), you have two options to use them: 1. Create a copy of the shortcut created by the ESP-IDF Tools Installer, and change the working directory of the new shortcut to the ESP-IDF directory you wish to use. 2. Alternatively, run ``cmd.exe``, then change to the ESP-IDF directory you wish to use, and run ``export.bat``. Note that unlike the previous option, this way requires Python and Git to be present in ``PATH``. If you get errors related to Python or Git not being found, use the first option.
