I am trying to understand the Traffic Light project. Some doubts..

1) There is a Beaglebone Black controller at "" Presumably, this is a microcontroller at "" Can this be replaced by a Forte_PC controller at localhost:6150x?

2.) What are the requirements for downlading/running this project?

3.) Why no ethernet segment is shown in the System Configuration

4.) Any write-up is available?

The Traficlight example has two different traffic light applications. The first one is a pedestrian crossing which is running on a beagleboneblack device with an expension PCB as it has been demonstrated at the Eclipse Con Europe 2 years ago. For startes I would not recomend this one and maybe we should even remove it from the repository.

There is a second application called PedestrianCrossing. This application runs on pure simulated devices, namely a UI device (UI) for turning the crossing on and of, a controller device where the control algorithms for the pedestrian crossings are running (Controler_1) and finally a simulated crossing (Lights) with a car light (red, orange, green) a pedestrian light (red & green) and a push button.

You can start these devices purely on your pc following the tutorials in the documentation. Please note in order to run the traffic light you need to compile your own FORTE where you add the trafficlight specific function blocks.

Regarding your question 3: in 4diac the Ethernet segment is currently used mainly for documentation purposes. The only feature which needs it is the experimental automatic communication generation. As we manually configured the communication this was not an issue here. But for the future we will definitely need to extend this.

Unfortunately there is not more documentation available but I hope my short description helps you.
