Hello I have a problem.
I am new to arduino and want to use a 1.3" oled display to just display somthing.
I watched some tutorials on how to use one and installed the Adafruit GFX and SSD1306 library but I can´t install it.
I always get this error:
Restart the IDE and see if that works. If you installed them properly, they can be found by browsing in file explorer to ...\Arduino\libraries\
If the library(s) were installed correctly and the ArduinoIDE still cannot find the code, your environmental pathing may be corrupted; can happen rarely for various reasons but just reinstall the Arduino application.
Adafruit has done a major software re-architecture on how the low-level SPI/I2C etc work, so even when your sketch calls 2 libraries, other libraries may be dependent. In a perfect world, library manages should keep this synchronized.
But, I do not use libraries this way. All libraries I use are located in each sketch folder ... Yes, lots of duplicates but when I Zip-up a folder for archive or sharing, I know that it will work again pending IDE and GCC concerns.) This also allows me to hack (frequently) the project confined library without mucking with the always-updated master copy in \libraries.
No, it is necessary because an upload is what I assume @loooool was trying to accomplish when they were interrupted by the compilation failure that was caused by them not installing the library dependency. Note that the Upload button is activated in the screenshot.
If you don't want to upload the sketch to your board, then don't, but installing an Arduino library doesn't do you much good if you never use it in a program on an Arduino board.
But it happens ALL the time here in the forums!
I think a large portion on Arduino'ites grab every library they can find ... "just in case" ... you know, global inflation is causing even Free-Open-Source code to become more expensive.
