These are some basic examples that cover some common use cases. They are intentionally crude and simple so that just the functional aspects of the displayio library can be seen. A fun thing to do would be to take one of these examples and modify it to try and add something new. Change the text color, make a sprite move around, etc.
Most of these examples assume a board with a built in display. See the Display and Display Bus section for information on built in vs. external displays. If you are not using a board with a built in display, then this line:
in the examples will not work. That would need to be substituted for lines that configure an external display.
