I wish I saw this like 4 hours ago
CircuitPython seems better for memory management and I love its file system, but honestly, the Adafruit libraries (mainly the graphic ones) aren’t that good compared to the MicroPython ones.
I also see that some developers have already created some MicroPython drivers for the PicoCalc so I’m discontinuing CircuitPython support in Picoware for now.
If anyone figures out the keyboard in the future, certainly tag me
Here’s a Draw class that handles graphics:

I ran into the same keyboard issue, which to my current understanding is a bit odd because a similar I2C setup in micropython works just fine.
