# Using the component manager for downloading dependencies
|
|
|
|
This example demonstrates how to use [IDF Component Manager](https://pypi.org/project/idf-component-manager/) for downloading dependencies from [ESP Component Registry](https://components.espressif.com). More details and use cases of IDF Component Manager can be found in the programming guide under `API Guides` -> `Tools` -> `IDF Component Manager`.
|
|
|
|
## How to use the example
|
|
### Hardware Required
|
|
|
|
This example is designed to work with any commonly available development kit.
|
|
|
|
### Build and Flash
|
|
|
|
Run `idf.py reconfigure` to configure this project. During CMake execution the component manager will process data from the manifest file `./main/idf_component.yml` where 2 dependencies are defined:
|
|
|
|
- `idf: ">=4.1"` - Specifies required version of ESP-IDF.
|
|
- `example/cmp: ">=3.3.3"` - Defines dependency on [example/cmp](https://components.espressif.com/component/example/cmp) component that is used by the main component.
|
|
|
|
CMake Output:
|
|
```
|
|
...
|
|
Solving dependencies requirements
|
|
Updating lock file at /home/user/esp-idf/examples/build_system/cmake/component_manager/dependencies.lock
|
|
Processing 2 dependencies:
|
|
[1/2] example/cmp
|
|
[2/2] idf
|
|
...
|
|
```
|
|
|
|
Content of the `./managed_components` directory after successful build:
|
|
```
|
|
> find ./managed_components
|
|
./managed_components
|
|
./managed_components/example__cmp
|
|
./managed_components/example__cmp/include
|
|
./managed_components/example__cmp/include/cmp.h
|
|
./managed_components/example__cmp/LICENSE
|
|
./managed_components/example__cmp/README.md
|
|
./managed_components/example__cmp/CMakeLists.txt
|
|
./managed_components/example__cmp/changelog.md
|
|
./managed_components/example__cmp/cmp.c
|
|
./managed_components/example__cmp/idf_component.yml
|
|
```
|
|
|
|
Flash the project and run the serial monitor to view the output:
|
|
|
|
```
|
|
idf.py -p PORT flash monitor
|
|
```
|
|
|
|
### Example Output
|
|
|
|
The example outputs a line from the `cmp_hello` function from the component downloaded by the component manager.
|
|
|
|
```
|
|
Hello from example component!
|
|
```
