//| :mod:`nativeio` --- Hardware accelerated behavior
//| =================================================
//|
//| .. module:: nativeio
//| :synopsis: Hardware accelerated behavior
//| :platform: SAMD21
//|
//| The `nativeio` module contains classes to provide access to IO accelerated
//| by hardware on the onboard microcontroller. The classes are meant to align
//| with commonly hardware accelerated IO and not necessarily match up with
//| microcontroller structure (because it varies).
//|
//| If the microcontroller doesn't not support the behavior in a hardware
//| accelerated fashion it throws a NotImplementedError on construction. Use
//| `bitbangio` module instead which only depends on
//| :py:class:`~nativeio.DigitalInOut` and is shared across hardware ports.
//|
//| Libraries
//|
//| .. toctree::
//| :maxdepth: 3
//|
//| AnalogIn
//| AnalogOut
//| DigitalInOut
//| I2C
//| PulseOut
//| PWMOut
//| SPI
//| TouchIn
//| UART
//|
//| All libraries change hardware state and should be deinitialized when they
//| are no longer needed. To do so, either call :py:meth:`!deinit` or use a
//| context manager.
//|
//| For example::
//|
//| import nativeio
//| from board import *
//|
//| with nativeio.I2C(SCL, SDA) as i2c:
//| i2c.scan()
//|
//| This example will initialize the the device, run
//| :py:meth:`~nativeio.I2C.scan` and then :py:meth:`~nativeio.I2C.deinit` the
//| hardware.
//|
//| Here is blinky::
//|
//| import nativeio
//| from board import *
//| import time
//|
//| with nativeio.DigitalInOut(D13) as led:
//| led.switch_to_output()
//| while True:
//| led.value = True
//| time.sleep(0.1)
//| led.value = False
//| time.sleep(0.1)
//|
