The serial port that is found should also be mapped to the HashMap so we can identify the object later. This is helpful because the ... Setting Up Event Listeners to Read Data Once the port is open, the serial port must know whenever there is data to be read. This approach is event driven rather than by polling. When the event is hit, a special ...

To begin writing the python file open a terminal and enter: “VIM gps.py” This will create and open a new file called “gps.py” and this will be where code will be written. The first line of the code should be “import serial”. “serial” is a python package for reading serial ports, adding this line allows that package to be used.

For this project I wrote a Python module that does this same task allowing anyone on any operating system to send commands to the controller in an easy to read form. It also provides a programming interface to the controller so that other code can directly issue commands. The Python module does rely on the PySerial module for the serial port IO.
