//| """Analog hardware support
//|
//| The `analogio` module contains classes to provide access to analog IO
//| typically implemented with digital-to-analog (DAC) and analog-to-digital
//| (ADC) converters.
//|
//| All classes change hardware state and should be deinitialized when they
//| are no longer needed if the program continues after use. To do so, either
//| call :py:meth:`!deinit` or use a context manager. See
//| :ref:`lifetime-and-contextmanagers` for more info.
//|
//| For example::
//|
//| import analogio
//| from board import *
//|
//| pin = analogio.AnalogIn(A0)
//| print(pin.value)
//| pin.deinit()
//|
//| This example will initialize the the device, read
//| :py:data:`~analogio.AnalogIn.value` and then
//| :py:meth:`~analogio.AnalogIn.deinit` the hardware. The last step is optional
//| because CircuitPython will do it automatically after the program finishes.
//|
//| For the essentials of `analogio`, see the `CircuitPython Essentials
//| Learn guide <https://learn.adafruit.com/circuitpython-essentials/circuitpython-analog-in>`_
//|
//| For more information on using `analogio`, see `this additional Learn guide
