Execution
Demo the ROS installation.
terminal 1
roscore
terminal 2
cd catkin_ws/ source devel/setup.bash rosrun motor_hat motor_hat_node
terminal 3
rosnode list rostopic list rostopic echo cmd
terminal 4
cd catkin_ws/ source devel/setup.bash rosrun motor_hat stop.py rosrun motor_hat on.py
TBD - QUESTION - Why isn't the message often not received by the motor_hat_node?
Code Inspection
The next line can be added to ~/.bashrc.
source ~/catkin_ws/devel/setup.bash roscd hat_node pwd cd src ls
Look at the code
emacs on.py& emacs motor_hat_node_cpp&
If emacs isn't installed use nano.
nano on.py
