You have to install the plugin manually via Help > Install new Software... . Use the following update site: http://eclipse.baeyens.it/update/V4/nightly

The installation might take a few minutes because it will install the Arduino Tools as well as required software such as the CDT. Furthermore it will download the newest version of the Arduino software and libraries.

scchart BlinkyModel {
    
    @Wrapper Clock, "500"
    input bool clock;
    
    @Wrapper DigitalWrite, "13"
    output bool light;
    
    initial state lightOff
    --> lightOn with clock / light = true;
    
    state lightOn
    --> lightOff with clock / light = false;
}

The available wrapper code snippets are defined in the snippets assets directory of the project in ftl files (FreeMarker template files). In the default configuration of a new SCCharts project for Arduino, the file main.ftl is processed to create the entry point of the program. Thus it includes other templates containing the available code snippets. The table below gives an overview of the available wrapper code snippets.

Note: To view ftl files with highlighting, you may want to install the FreeMarker IDE feature from the JBoss Tools. However, this is not necessary to work with KIELER. JBoss Tools is available in the Eclipse Market Place and via update site. The update site for stable releases is http://download.jboss.org/jbosstools/neon/stable/updates/ . Note that only the FreeMarker IDE feature is required (Abridged JBoss Tools > FreeMarker IDE).

Build the project:

With the mouse over the SCT file in the project explorer, perform Right Click > Run As > KiCo Compilation.

A launch config is created, which compiles the model to C code and creates wrapper code from the annotations in the model file. Afterwards this output is compiled and deployed to the Arduino board, by using the launch shortcut from the Arduino Plugin. If any errors occur, you can see them in the Console View.

For a deeper understanding of the project launch and initialization, take a look at the wiki page for PromAfter the modeling is done, the project can be built. Select Project > Build Project. This will create a new folder kieler-gen with the compiled model file. Further the wrapper code for the model is processed. After the build finished sucessfully, the ino file for the project has been updated with the new wrapper code for the model, and thus the project can be deployed to the Arduino board. The Eclipse Arduino Plugin provides an upload button for this task in the toolbar.

Excluding the simulation folder from the CDT build

A simulation of models is created as part of a build inside kieler-gen/sim/bin. The files inside the sim folder are compiled separately and should not be compiled using the CDT. Otherwise errors will occur, for example because every simulation has its own main function and the CDT expects only one for the project.

Thus the folder kieler-gen/sim has to be excluded from the CDT build. Therefore select the folder and do Right Click > Resource Configurations > Exclude From Build.

Simulating the model

To use the simulation inside the folder kieler-gen/sim/bin, first change to the Simulation Perspective, which provides new buttons in the toolbar. The executables in the bin folder can then be launched via Right Click > KIELER Simulation. The output of a running simulation can be seen in the Data Pool View.
