|
.. note::
|
|
Currently only 64-bit versions of Windows are supported. 32-bit Windows can use the :doc:`Legacy GNU Make Build System<../get-started-legacy/windows-setup>`.
|

|
|
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're going to use the Command Prompt, but after ESP-IDF is installed you can use :doc:`Eclipse <eclipse-setup>` or another graphical IDE with CMake support instead.
|
|
|
|
.. only:: esp32
|
|
|
|
.. note::
|
|
Previous versions of ESP-IDF used the :doc:`Legacy GNU Make Build System<../get-started-legacy/windows-setup>` and MSYS2_ Unix compatibility environment. This is no longer required, ESP-IDF can be used from the Windows Command Prompt.
|
|
|
|
.. note::
|
|
Limitation: the installation path of Python or ESP-IDF must not contain white spaces or parentheses.
|
|
|
|
Limitation: 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 and reboot the computer.

ESP-IDF Tools Installer
|
|
=======================
|
|
|
|
The easiest way to install ESP-IDF's prerequisites is to download the ESP-IDF Tools installer from this URL:
|
|
|
|
https://dl.espressif.com/dl/esp-idf-tools-setup-2.4.exe
|
|
|
|
.. IMPORTANT: Next time this link is updated, please go to get-started/index.rst and rewrite the section under "Alternative File Downloads ... Windows". Then delete this comment.
|
|
|
|
The installer includes the cross-compilers, OpenOCD, CMake_ and Ninja_ build tool. The installer can also download and run installers for Python_ 3.7 and `Git For Windows`_ if they are not already installed on the computer.
|
|
|
|
The installer also downloads one of the ESP-IDF release versions, or offers to use an existing one, if already present on your PC. If you don't have one, please choose a directory for downloading ESP-IDF. The recommended directory is ``%userprofile%\esp`` where ``%userprofile%`` is your home directory. If you do not have it yet, please run the following command to create a new one:
|
|
|
|
.. code-block:: batch
|
|
|
|
mkdir %userprofile%\esp
|
|
|
|
|
|
At the end of installation, if you checkout ``Run ESP-IDF Command Prompt (cmd.exe)``, a new Windows Power Shell, i.e. the ESP-IDF Command Prompt will pop up.

|
Using the Command Prompt
|
|
========================
|
|
|
|
For the remaining Getting Started steps, we're 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.
|
|
|
|
Next Steps
|
|
==========
|
|
|
|
If the ESP-IDF Tools Installer has finished successfully, then the development environment setup is complete. Proceed directly to :ref:`get-started-start-project`.
