Introduction

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

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

Usage Example

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')
