Nov 29, 2023 · I'm not sure about Arduino IDE 2.x. The simplest solution (without creating a library) is to copy your .h file to the project folder. Then you include it with.

Oct 8, 2020 · I'm not sure what "add file" does. It allows you to add an existing file to a tab in the IDE. That file is then saved with the main .ino file as normal. See detail on how to add a header file to Arduino Sketch. When I add a file to a sketch, such as a example.h file, the behaviour of the Arduino IDE is a little confusing.

When you want to add a library manually, you need to download it as a ZIP file, expand it and put in the proper directory. The ZIP file contains all you need, including usage examples if the author has provided them.

Feb 11, 2018 · In order to use a C function in a C++ file, you need to wrap the function's declaration in extern "C" {}. That just adds one more complication so, at least to get started, I recommend to just use .cpp files instead of .c. All the information you find on writing libraries will apply to your goal.

Jun 30, 2015 · Have you follow these steps shown on the arduino site ? In you Arduino Sketch folder there is a folder called Libraries, create a folder there and put your header file in that folder and restart the Arduino IDE. For example (PC): You can now use it in all your projects.

Feb 20, 2013 · I'm currently writing an Arduino library and I want to include files in a subdirectory within the library folder. More specifically, I want the files to be accesible from the Arduino sketch. This is my directory structure: MyLib/MyLib.cpp MyLib/MyLib.h MyLib/Extra/SomeNiceFunctions.cpp MyLib/Extra/SomeNiceFunctions.h

After making a symlink in the /usr/share/arduino/libraries directory you must make sure that there is a header file with the exact name of the directory, apparently that's how arduino is set up to include them.

Apr 10, 2020 · I'm required to have each ino file in a directory of the same name. I can add the files to main_program by adding (e.g.) ../module1/module1.{cpp,h}. But, I discover that it has actually copied module1.{cpp,h} to main_program/.

Nov 30, 2013 · Is there a way to include a file using a relative link rather than an absolute one? For example: I know the most obvious answer is to place the include file in the same folder as the main '.ino' file, so it will automatically be included.
