Generating projects for Espressif IoT Development Framework (ESP-IDF)
Qmlprojectexporter can export a Qt Quick Ultralite application as an ESP-IDF project, which can then be configured and built using Espressif IoT Development Framework (ESP-IDF).
Export an ESP-IDF project
Call qmlprojectexporter with the following arguments to export a project:
| Option | Description |
|---|---|
${QUL_DIR}/bin/qmlprojectexporter | Tool to be called. |
path/to/some.qmlproject | QML project file to be exported. |
--platform <platform_name> | Platform name that is to be exported. |
--project-type esp-idf | Use ESP-IDF project format. |
--toolchain <compiler_id> | This provides information about which compiler type the generated options should be compatible with. The only option compatible with ESP-IDF is gnu. |
--cxx-standard <C++ standard> | Optionally, specify the C++ standard to use when processing the interface files listed in the InterfaceFiles section of the QML project file. |
--outdir <path> | The path the project will be exported to. |
--generate-entrypoint | Use this option if the Qt Quick Ultralite application does not already contain a main function. |
--boarddefaults=<qul_dir>/platform/boards/<platform>/cmake/BoardDefaults_32bpp_default.qmlprojectconfig | The board defaults need to be provided per board to provide information about color depth and asset formats. |
--platform-metadata <qul_dir>/platform/boards/<platform>/<platform>-<color_depth>_<OS>_<compiler>-metadata.json | Specify the metadata file to be used to export the platform. The reference Espressif platform ports use a custom metadata file that is needed to export the platform properly. The metadata file is located in the reference port's directory. |
--selector a[,b...] | In case your QML project uses selectors to find QML files and resources, provide these as a comma-separated list. |
--include-metadata-extra-target <example_name> | Specify the name of the example/demo to export the C++ files from it. Note: This should only be used when exporting Qt Quick Ultralite demos and examples. |
Build the exported ESP-IDF project
Exporting a project with the command described above generates an ESP-IDF project into the output folder. The generated project can be built with the ESP-IDF tools in the output folder:
idf.py build
