Python

You may already have this installed. If not, here's the official website you can go to for install info:

To check if it's already installed, try running this at a command line:

python3 --version

python3 --version

Matplotlib

This is used to generate plots. Use the official installation instructions here to install for your platform:

Pillow/PIL

This is the Python Imaging Library which is used to render the plots onto bitmaps that can be sent to the TFT display. Install instructions are here:

psutil

This is a Python library used to gather system data. The PyPi page is here and the install instructions are here:
