c++ sample

Run example for subscribe, you can open a terminal to executing command:

ros2 run demo_nodes_cpp listener

Open a new terminal to executing command to publish:

ros2 run demo_nodes_cpp talker



rclnodejs sample

Run example for subscribe, you can open a terminal to executing command:

cd /usr/local/Advantech/ros/foxy/sample_code/rclnodejs_sample
node sub.js

Open a new terminal to executing command to publish:

cd /usr/local/Advantech/ros/foxy/sample_code/rclnodejs_sample
node pub.js

cd /usr/local/Advantech/ros/foxy/sample_code/rclpy_sample
python3 publish.py

turtlesim

Open a terminal to start turtlesim by executing command:

ros2 run turtlesim turtlesim_node

The simulator window should appear, with a random turtle in the center.

Open a new terminal, run a new node to control the turtle in the first node by executing command:
