This is interesting. A current project is converting the software for a Wemos
Microcontroller in Arduino format (C++?) to micropython for a Raspberry Pi PICO
W. The Wemos program has a Loop that periodically reads a button pressed
state. I haven't dug into it for awhile so I am trying to refresh my memory on
it.

As you say, I'll try to work out what is going on in the code before I do anything more exotic.
