ESP-IDF Tools Installer

The easiest way to install ESP-IDF's prerequisites is to download the ESP-IDF Tools

installer form this URL: https://dl.espressif.com/dl/esp-idf-tools-setup-2.0.exe

The installer includes the cross-compilers, OpenOCD, cmake and Ninja build tool, and a

configuration tool called mconf-idf. 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 offers to download one of the ESP-IDF release versions.

Using the Command Prompt

For the remaining Getting Started steps, we're going to use the Windows Command

Prompt.

ESP-IDF Tools Installer 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.
