Once you're Pi 5 is all set up and you've got the RGB Matrix panels all wired you're ready to test it out!
As always, you need to activate the virtual environment before running the example. If you haven't already then activate it like this.
source ~/venvs/blinka_venv/bin/activate
Next you can run the single_panel_simpletest.py script.
python single_panel_simpletest.py
The code for this example is embedded below. You can download it, or copy/paste the text into a file.
