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

This driver depends on:

• Adafruit CircuitPython

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

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')
