ROSSerial_mbed for Melodic Distribution
The Robot Operating System (ROS) is a flexible framework for writing robot software. It is a collection of tools, libraries, and conventions that aim to simplify the task of creating complex and robust robot behavior across a wide variety of robotic platforms.
The rosserial_mbed package allows to write ROS nodes on any mbed enabled devices and have them connected to a running ROS system on your computer using the serial port.

rosserial_mbed Hello World example for Melodic Morenia distribution
Running the Code
Now, launch the roscore in a new terminal window:
Quote:
$ roscore
Next, run the rosserial client application that forwards your MBED messages to the rest of ROS. Make sure to use the correct serial port:
Quote:
$ rosrun rosserial_python serial_node.py /dev/ttyACM0
Finally, watch the greetings come in from your MBED by launching a new terminal window and entering :
Quote:
$ rostopic echo chatter
