Our Eclipse IDE resources here may well be old, we’ve switched over to using VSCode

Installing Eclipse IDE

https://docs.espressif.com/projects/esp-idf/en/stable/esp32/get-started/eclipse-setup.html

Install missing prerequisites

Install Python (the Espressif Windows all-in-one toolchain installed embedded Python, not Python) from: https://www.python.org/downloads/
(Installs to here by default: C:\Users\Dev\AppData\Local\Programs\Python\ )
Note if the current Python release is very new you may want to select the previous version in case the ESP tools haven’t been updated for it yet.

Install Git from: https://git-scm.com/downloads
Use default install options.

Install Eclipse

Download the Eclipse IDE Installer for your platform from eclipse.org
Choose “Eclipse IDE for Embedded C/C++ Developers” when selecting the version to use.

Open workspace

Run Eclipse IDE and when prompted to select a Workspace Directory, select a folder where you’ll want to store project files (ENSURE THERE ARE NO SPACES IN THE PATH)
