Debounces an arbitrary predicate function (typically created as a lambda) of 0 arguments. The constructor also accepts a digital pin as a convienence.

Dependencies

This driver depends on:

• Adafruit CircuitPython <https://github.com/adafruit/circuitpython>_
• Adafruit Ticks <https://github.com/adafruit/Adafruit_CircuitPython_Ticks>_

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>_.

Usage Example

.. code-block:: python

import board
import digitalio
from adafruit_debouncer import Debouncer

pin = digitalio.DigitalInOut(board.D12)
pin.direction = digitalio.Direction.INPUT
pin.pull = digitalio.Pull.UP
switch = Debouncer(pin)

while True:
    switch.update()
    if switch.fell:
        print('Just pressed')
    if switch.rose:
        print('Just released')
    if switch.value:
        print('not pressed')
    else:
        print('pressed')
