How to build PlatformIO based project
2+
=====================================
3+
4+
See <https://github.com/cnlohr/rv003usb/tree/master/demo_composite_hid>
5+
6+
1. [Install PlatformIO Core](https://docs.platformio.org/page/core.html)
7+
2. Download [development platform with examples](https://github.com/Community-PIO-CH32V/platform-ch32v/archive/develop.zip)
8+
3. Extract ZIP archive
9+
4. Run these commands:
10+
11+
```shell
12+
# Change directory to example
13+
$ cd platform-ch32v/examples/ch32fun-rv003usb-composite-hid
14+
15+
# Build project
16+
$ pio run
17+
18+
# Upload firmware
19+
$ pio run --target upload
20+
21+
# Upload firmware for the specific environment
22+
$ pio run -e ch32v003f4p6_evt_r0 --target upload
23+
24+
# Clean build files
25+
$ pio run --target clean
26+
```

This directory is intended for project header files.
3+
4+
A header file is a file containing C declarations and macro definitions
5+
to be shared between several project source files. 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

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 <Foo.h>
33+
#include <Bar.h>
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+
