//| """Support for PWM based protocols
|
|
//|
|
|
//| The `pwmio` module contains classes to provide access to basic pulse IO.
|
|
//|
|
|
//| 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 time
|
|
//| import pwmio
|
|
//| import board
|
|
//|
|
|
//| pwm = pwmio.PWMOut(board.LED)
|
|
//| pwm.duty_cycle = 2 ** 15
|
|
//| time.sleep(0.1)
|
|
//|
|
|
//| This example will initialize the the device, set
|
|
//| :py:data:`~pwmio.PWMOut.duty_cycle`, and then sleep 0.1 seconds.
|
|
//| CircuitPython will automatically turn off the PWM when it resets all
|
|
//| hardware after program completion. Use ``deinit()`` or a ``with`` statement
|
|
//| to do it yourself.
|
|
//|
|
|
//| For the essentials of `pwmio`, see the `CircuitPython Essentials
|
|
//| Learn guide <https://learn.adafruit.com/circuitpython-essentials/circuitpython-pwm>`_.
