Quickstart

See Usage section for more details.

Install

no_std

espup install
# Unix
. $HOME/export-esp.sh
# Windows
%USERPROFILE%\export-esp.ps1

std: Installing esp-idf via espup is not mandatory, as esp-idf-sys already takes care of it, but has some benefits.

espup install --esp-idf-version <ESP_IDF_VERSION>
# Unix
. $HOME/export-esp.sh
# Windows
%USERPROFILE%\export-esp.ps1

Warning

The generated export file, by default export-esp, needs to be sourced in every terminal before building an application.

Uninstall

espup uninstall

Update

espup update

Known Issues or Limitations

If installing esp-idf in Windows, only all targets is allowed.

In Windows, when installing esp-idf fails with:

ERROR: Could not find a version that satisfies the requirement windows-curses; sys_platform == "win32" (from esp-windows-curses) (from versions: none)
ERROR: No matching distribution found for windows-curses; sys_platform == "win32"

Solution: Use a python version between 3.6 and 3.10 as 3.11 Python wheels are not yet released for Windows.
