Help on module gpiod:NAME    gpiod - Python bindings for libgpiod.DESCRIPTION    This module wraps the native C API of libgpiod in a set of python classes.CLASSES    builtins.object        Chip        ChipIter        Line        LineBulk        LineEvent        LineIter        class Chip(builtins.object)     |  Represents a GPIO chip.     |       |  Chip object manages all resources associated with the GPIO chip     |  it represents.     |       |  The gpiochip device file is opened during the object's construction.     |  The Chip object's constructor takes a description string as argument the     |  meaning of which depends on the second, optional parameter which defines     |  the way the description string should be interpreted. The available     |  options are: OPEN_BY_LABEL, OPEN_BY_NAME, OPEN_BY_NUMBER, OPEN_BY_PATH,     |  and OPEN_LOOKUP. The last option means that libgpiod should open the chip     |  based on the best guess what the path is. This is also the default if the     |  second argument is missing.     |       |  Callers must close the chip by calling the close() method when it's no     |  longer used.     |       |  Example:     |       |      chip = gpiod.Chip('gpiochip0', gpiod.Chip.OPEN_BY_NAME)     |      do_something(chip)     |      chip.close()     |       |  The gpiod.Chip class also supports controlled execution ('with' statement).     |       |  Example:     |       |      with gpiod.Chip('0', gpiod.Chip.OPEN_BY_NUMBER) as chip:     |          do_something(chip)     |
