How to tell vscode to check for libraries folder ?

[eagl1]

Hi,

I'm trying to compile my ESP32 code, but vscode don't know where my "libraries" folder is.

How to set the folder's path ?

Almost same problem as #1033

Can you try installing the library that provides TFT_eSPI.h (and any other headers you need) using the library manager in VS Code? Run the "Arduino: Library Manager" command in the VS Code command palette. If you started using the Arduino CLI in the latest version of this extension, libraries may be in a different directory now (see #1595).

OK, after a many error/trail, I solved most of the errors.

But left this one:

I solved part of the problem with these settings:

"includePath": [ "${workspaceFolder}/**", "D:/Program_Files/Arduino/hardware/arduino-esp32-master/libraries", "D:/Program_Files/Arduino/hardware/arduino-esp32-master/cores/esp32", "D:/Program_Files/Arduino/libraries", "D:/Program_Files/Arduino/hardware/tools/avr/lib/gcc/avr/7.3.0/include" ],

But I moved the project folder and got the errors again !

Working with vscode isn't easy.

I think the procedure has to be done is the following:

1. Compile the code without the included libraries.
2. vscode will generate necessary ".json" files in the ".vscode" folder, for the compiled code. Like this:

3. After that, the programmer can add the libraries path in the "c_cpp_properties". Like this:

It seems that on Windows, libraries must be in the C:\Users\[user]\Documents\Arduino\libraries folder, then they will be found by the compiler. I tried @eagl1 's trick of compiling without the headers first to get the c_cpp_properties.json file but the only way I'm able to compile is if I copy my libraries to the folder I mentioned above.

[eagl1]

Yes, that is on Windows.

You can use the path C:\Users[user]\Documents\Arduino\libraries, and I'm sure this is for the new Arduino IDE 2.0, as I'm working with the legacy Arduino IDE. I'm happy I learned how to setup this wonderful IDE.

But I got back to the legacy Arduino IDE, it's more convenient for me more than vscode and the new Arduino IDE.

Maybe it will be helpful - maybe not - I had a project already created in the Arduino IDE then I decided to use the Arduino extension for VS Code.
I was able to verify the project and upload - no problems detected. But the headers were highlighted - like on the screenshots shown earlier. Of course it was not possible to jump to the header too. But the compiler somehow didn't have the problems.
In the c_cpp_properties.json I had all needed paths (I didn't add it manually).

So I created the new folder, new .ino file, just pasted the content from the existing project - it was needed only to set the port, board and the output folder - no build problems, no problems with uploading.

I checked the old and new cofig files in .vscode i neach project. Looks like we have some differences.

arduino.json:

c_cpp_properties.json (additional content in the old project):

c_cpp_properties.json again with this diff section and full includePath content:

So I copied the new config files to the old project - now looks like everything is ok.

1. The differences in arduino.json are just in the sequence of the arguments.
2. The workspaceFolder should contain your application libraries. Like this:

3. The includePath should contain the hardware libraries.
