GSD (Ground Station Datalogger)

GUI created to visualize and save incoming data from sensors connected to an arduino using serial communication.

Capabilities

• Realtime plotting every 500 ms.
• Visualization of last 7.5 seconds of data.
• Data saving for up to 8 graphs at the same time.
• Test mode with data saving capabilites.
• Automatic Arduino detection.

How to install

To install required packages run the code below on cmd inside 'GUI-Datalogger_Python' folder.

pip install -r requirements.txt

How does it work?

Communication

Software should automatically detect COM port when an Arduino is connected to the computer (software needs to be restarted). There's a manual way to select COM port inside serialcomm.py file.

If the software doesn't detect an Arduino, test mode will start. Test mode status can be seen above Start and Stop buttons.

Incoming Arduino data needs to have a baudrate of 9600 and needs to be printed as a string with the following structure.

humidity, temperature, pressure, altitude, verticalaccel, magneticfield, otherdata1, otherdata2

Data plotting is made every 500 ms on the main.py file so incoming serial data doesn't need any timer for printing data.

Data saving

To begin data saving just click the Start button, you can see elapsed time on the timer above the buttons, to stop data saving click Stop.

Data will be saved on one or more csv files located on the saves folder, this depends on how many graphs you want to save data from. Needs to be changed from code, default = 8

Known bugs/problems

• Graphs position and size changes when hidden and shown multiple times.
