GPIO Input

From: Generic

Class: herosdevices.core.gpio.GPIOInput

Driver Quality Index: beta

A single GPIO configured as input.

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.GPIOInput 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	Currently unused.
bias	<class ‘str’>	AS_IS	bis to apply to the GPIO pin. Possible values: AS_IS (default), DISABLED, PULL_DOWN, PULL_UP, UNKNOWN
debounce_ms	<class ‘int’>	5	debouncing time in milliseconds.
edge_detection	<class ‘str’>	NONE	If given it performs the specified edge detection an issues an edge event. Valid values are BOTH, FALLING, NONE, RISING. For this to work, an asyncio loop has to given as well.
loop	asyncio.events.AbstractEventLoop | None	None	asyncio loop in which the edge detection task can be performed. This is required if edge detection is set.
