My pyportal comes with a demo program which retrieves and displays quotes from Adafruit.com/quotes. I made the required changes to the secret.py file and it ran fine. Now I need to understand why! The Pyportal has some initial file on it but it doesn't have a adafruit-circuitpython-pyportal-XXXX.uf2 file on it. Questions:
1. What exactly is the .uf2 file for? Is it only needed when you are working with MU?
2. Also, I do not understand what code is reading the secret.py file. It isn't referenced in the code.py file. How is the device reading the secret.py file?
I hope I can get some help with these questions. I'm enjoying my CPB and now my Pyportal but I'm trying to understand Circuit Python as well as the devices.
Thanks.
