GPIO Output¶

From: Generic

Class: herosdevices.core.gpio.GPIOOutput

Driver Quality Index: beta

A single GPIO configured as output.

The access to the GPIO is based on libgpiod and thus uses the standard linux kernel interface (i.e. /dev/gpiochip* devices).

Bold arguments are mandatory. For more information on the listed arguments refer to the class documentation: herosdevices.core.gpio.GPIOOutput If parameters appear in this list but not in the class definition, please recursively check the linked base classes for the definition of the parameter.

Argument	Type	Default Value	Description
gpiochip	<class ‘int’>		number of the gpiochip as exposed by the linux kernel.
pin	<class ‘int’>		number of the GPIO pin
drive	<class ‘str’>	PUSH_PULL	how to drive the GPIO pin. Possible values: PUSH_PULL (default), OPEN_SOURCE, OPEN_DRAIN
