Using multiple esp-idf versions for different projects (vscode)

[zazas321]

Hello. I have initially installed v4.4.0 esp-idf version using vscode esp-idf extension and been using this without any issues.

The installation directory:
esp-idf path:

Code: Select all

C:\Users\MY_USER\esp\esp-idf

esp-idf tools path

Code: Select all

C:\Users\MY_USER\.espressif

Recently, I have been given a project which needs esp-idf v5.0.1
I have downloaded esp-idf v5.0.1 offline installer and installed new esp-idf version version
https://dl.espressif.com/dl/esp-idf/

New esp-idf version is now installed in:

Code: Select all

C:\Espressif\frameworks\esp-idf-v5.0.1

.

So now I have 2 different esp-idf versions in different directories. My question is very simple. When I open some project, how can I choose which esp-idf version to choose when building it?

[bidrohini]

To use a specific version of the ESP-IDF with your project, you can set the IDF_PATH environment variable to point to the directory of the desired version of the ESP-IDF.

[zazas321]

Thanks for reply. Il test it out.

Although I was hoping there is more elegant solution rather than changing IDF_PATH variable back and forth

[zazas321]

The solution that you proposed does not seem to work at all.

I now have installed 2 different esp-idf versions in C:/Espressif/frameworks:
esp-idf-v4.4.4
and
esp-idf-v5.0.1

I opene example project from C:\Espressif\frameworks\esp-idf-v5.0.1\examples\get-started\hello_world
and it seems to me that it is using esp-idf v4.4.4 to build v5.0.1 example even though I have added environemnt variable

Code: Select all

IDF_PATH=C:\Espressif\frameworks\esp-idf-v5.0.1

Code: Select all

Another strange thing, when I build project, a dependancies.lock file is created and added to my project directory. It contains the following:

Code: Select all

dependencies:
  idf:
    component_hash: null
    source:
      type: idf
    version: 4.4.4
manifest_hash: dcf4d39b94252de130019eadceb989d72b0dbc26b552cfdcbb50f6da531d2b92
target: esp32
version: 1.0.0

I dont know why it does that

[zazas321]

I think I just found a bug.

I completely deleted the v.4.4.4 esp-idf version from my computer and only have esp-idf-v5.0.1 now.


I open a blank example project from:

Code: Select all

C:\Espressif\frameworks\esp-idf-v5.0.1\examples\get-started\sample_project

When trying to build now, I get an error:

Code: Select all

It wont build because for some reason its looking for esp-idf-v4.4.4 even though I have just deleted it and its DEFINATELY not set in environment variables.

Why vscode wants to use v4.4.4? Is there a setting that tells vscode which esp-idf version to use?

[MicroController]

In VS code, press F1 then search for and start >ESP-IDF: Configure ESP-IDF extension to set up the correct paths/version of ESP-IDF. This should get you one step closer to making it work.

Yep that seems to work fine. Thanks!
