How the FMU is build and used#
The fmu code & cmake project is created by the sdv_dbc_util
.
The FMU can be found here: <outpufolder>/examples/system_demo_example/generated/fmu_DemoExampleFMU/fmus
Before the project can be used, following steps needs to be done:
required configuration files have to be put into the subfolder.
function OpenAPILoad() needs to be updated in the model.cpp file.

The prepared files are copied during cmake configuration.
file (COPY ${PROJECT_SOURCE_DIR}/fmu/resources/fmu_vehicle_devices_basic_services.toml DESTINATION ${PROJECT_SOURCE_DIR}/generated/fmu_DemoExampleFMU/DemoExampleFMU/resources)
file (COPY ${PROJECT_SOURCE_DIR}/fmu/resources/fmu_complex_service.toml DESTINATION ${PROJECT_SOURCE_DIR}/generated/fmu_DemoExampleFMU/DemoExampleFMU/resources)
# Overwrite model.cpp with an identical file but loads all components in OpenAPILoad(const std::string& resources)
