In the EEROS library you will find a directory with examples. Open a shell and run roscore. Open another shell in the build directory of your EEROS library and run sudo -E examples/ros/rosTest2 -c RosTest2Config.json.

This example runs your EEROS application as a ROS node under the name /eerosNode. It publishes three topics

• /test/val (of type double)
• /test/state (of type boolean)

Use the same tools as in controlsystemros1 to show nodes, topics and messages.

Open another shell in the build directory of your EEROS library and run rosNodeTalker. This is not a EEROS program but simply starts a ROS node which publishes a couple of test topics. As soon as rosNodeTalker runs, your example application will receive the two topics

• /rosNodeTalker/val (of type double)
• /rosNodeTalker/state (of type boolean)

and logs its transported message values into the console. Use

$ rqt_graph

to show a graph with all involved nodes together with their topics.
