Displays
-------------

Drivers used to display information. Either pixel or segment based.

Pixel based displays are implemented in two different ways. The original method called "framebuf"
uses a traditional frame buffer model where all pixels are stored in the microcontroller's ram. The
newer method called "displayio" generates the pixels on the fly and relies on the display's ram to
store the final pixels. "displayio" drivers will also work with CircuitPython to display error
messages and other output to the display when the user code is not using it.

The "displayio" drivers are recommended.

Distance Sensors
------------------

These sensors measure the ``distance`` to another object and may also measure light level (``light`` and ``lux``).
