Hi.
What code/project are you referring to?
Regards,
Sara

I know my answer. I just purchased the Raspberry pico PDF book and downloaded some code along with the booki.
I know that some modules require libraries, like the OLED and LCD modules and more. And looking at the code I did not see them. Then I saw the Github page with code for the book. Libraries are there. That’s all.

Great.
I’ll mark this issue as resolved. If you need further help, you just need to open a new question in our forum.
