You request the use of a 6 | header file in your project source file (C, C++, etc) located in `src` folder 7 | by including it, with the C preprocessing directive `#include'. 8 | 9 | ```src/main.c 10 | 11 | #include "header.h" 12 | 13 | int main (void) 14 | { 15 | ... 16 | } 17 | ``` 18 | 19 | Including a header file produces the same results as copying the header file 20 | into each source file that needs it. Such copying would be time-consuming 21 | and error-prone. With a header file, the related declarations appear 22 | in only one place. If they need to be changed, they can be changed in one 23 | place, and programs that include the header file will automatically use the 24 | new version when next recompiled. The header file eliminates the labor of 25 | finding and changing all the copies as well as the risk that a failure to 26 | find one copy will result in inconsistencies within a program. 27 | 28 | In C, the usual convention is to give header files names that end with `.h'. 29 | It is most portable to use only letters, digits, dashes, and underscores in 30 | header file names, and at most one dot. 31 | 32 | Read more about using header files in official GCC documentation: 33 | 34 | * Include Syntax 35 | * Include Operation 36 | * Once-Only Headers 37 | * Computed Includes 38 | 39 | https://gcc.gnu.org/onlinedocs/cpp/Header-Files.html 40 | -------------------------------------------------------------------------------- /lib/README: -------------------------------------------------------------------------------- 1 | 2 | This directory is intended for project specific (private) libraries. 3 | PlatformIO will compile them to static libraries and link into executable file. 4 | 5 | The source code of each library should be placed in a an own separate directory 6 | ("lib/your_library_name/[here are source files]"). 7 | 8 | For example, see a structure of the following two libraries `Foo` and `Bar`: 9 | 10 | |--lib 11 | | | 12 | | |--Bar 13 | | | |--docs 14 | | | |--examples 15 | | | |--src 16 | | | |- Bar.c 17 | | | |- Bar.h 18 | | | |- library.json (optional, custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html 19 | | | 20 | | |--Foo 21 | | | |- Foo.c 22 | | | |- Foo.h 23 | | | 24 | | |- README --> THIS FILE 25 | | 26 | |- platformio.ini 27 | |--src 28 | |- main.c 29 | 30 | and a contents of `src/main.c`: 31 | ``` 32 | #include 33 | #include 34 | 35 | int main (void) 36 | { 37 | ... 38 | } 39 | 40 | ``` 41 | 42 | PlatformIO Library Dependency Finder will find automatically dependent 43 | libraries scanning project source files. 44 | 45 | More information about PlatformIO Library Dependency Finder 46 | - https://docs.platformio.org/page/librarymanager/ldf.html 47 | -------------------------------------------------------------------------------- /platformio.ini: -------------------------------------------------------------------------------- 1 | ;
