You request the use of a +header file in your project source file (C, C++, etc) located in `src` folder +by including it, with the C preprocessing directive `#include'. + +```src/main.c + +#include "header.h" + +int main (void) +{ + ... +} +``` + +Including a header file produces the same results as copying the header file +into each source file that needs it. Such copying would be time-consuming +and error-prone. With a header file, the related declarations appear +in only one place. If they need to be changed, they can be changed in one +place, and programs that include the header file will automatically use the +new version when next recompiled. The header file eliminates the labor of +finding and changing all the copies as well as the risk that a failure to +find one copy will result in inconsistencies within a program. + +In C, the convention is to give header files names that end with `.h'. + +Read more about using header files in official GCC documentation: + +* Include Syntax +* Include Operation +* Once-Only Headers +* Computed Includes + +https://gcc.gnu.org/onlinedocs/cpp/Header-Files.html diff --git a/lib/README b/lib/README new file mode 100644 index 0000000..9379397 --- /dev/null +++ b/lib/README @@ -0,0 +1,46 @@ + +This directory is intended for project specific (private) libraries. +PlatformIO will compile them to static libraries and link into the executable file. + +The source code of each library should be placed in a separate directory +("lib/your_library_name/[Code]"). + +For example, see the structure of the following example libraries `Foo` and `Bar`: + +|--lib +| | +| |--Bar +| | |--docs +| | |--examples +| | |--src +| | |- Bar.c +| | |- Bar.h +| | |- library.json (optional. for custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html +| | +| |--Foo +| | |- Foo.c +| | |- Foo.h +| | +| |- README --> THIS FILE +| +|- platformio.ini +|--src + |- main.c + +Example contents of `src/main.c` using Foo and Bar: +``` +#include +#include + +int main (void) +{ + ... +} + +``` + +The PlatformIO Library Dependency Finder will find automatically dependent +libraries by scanning project source files. + +More information about PlatformIO Library Dependency Finder +- https://docs.platformio.org/page/librarymanager/ldf.html diff --git a/platformio.ini b/platformio.ini new file mode 100644 index 0000000..561a46b --- /dev/null +++ b/platformio.ini @@ -0,0 +1,18 @@ +;
