//| """Touch related IO

//|

//| The `touchio` module contains classes to provide access to touch IO typically

//| accelerated by hardware on the onboard microcontroller.

//|

//| 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 more information about working with the `touchio` module in CircuitPython,

//| see `this Learn guide page <https://learn.adafruit.com/circuitpython-essentials/circuitpython-cap-touch>`_.

//|

//| **Limitations**: `touchio` on RP2350 must have a pull-up resistor to 3.3V

//| instead of ground and set the ``pull=Pull.UP`` parameter when constructing

//| a `TouchIn` object, due to GPIO hardware limitations.

//|

//| Example::

//|

//| import touchio

//| from board import *

//|

//| touch_pin = touchio.TouchIn(D6)

//| print(touch_pin.value)

//|

//| This example will initialize the the device, and print the

//| :py:data:`~touchio.TouchIn.value`.
