如何在 Raspberry Pi 上为 Google Assistant SDK 连接按钮

Question

Google 助理 SDK 示例要求用户在与 Google 助理交谈之前按 Enter。

我想知道有没有办法将一个按钮连接到一个 RPI GPIO 引脚并让它触发 G.Assistant。

 while True:
        if wait_for_user_trigger:
            click.pause(info='Press Enter to send a new request...')
        continue_conversation = assistant.converse()
        # wait for user trigger if there is no follow-up turn in
        # the conversation.
        wait_for_user_trigger = not continue_conversation

        # If we only want one conversation, break.
        if once and (not continue_conversation):
            break

我想这将是我在连接 GPIO 库时进行更改的区域。

我应该如何实施它？我是 Python 和 Raspberry Pi 的新手。我确实有 Java 背景和自动化历史。

这可能会有所帮助：

...
import os.path
import RPi.GPIO as GPIO
...
CLOSE_MICROPHONE = embbeded_assistant_pb2.ConverseResult.CLOSE_MICROPHONE

GPIO.setmode(GPIO.BMC)
GPIO.setup(18, GPIO.IN, pull_up_down=GPIO.PUD_UP)
GPIO.setup(23, GPIO.OUT)
...
while True:
    if wait_for_user_trigger:
        input_state = GPIO.input(18)
        if input_state == True:
            GPIO.output(23, False)
            continue
        else:
            GPIO.output(23, True)
            pass
        #click.pause(info='Press Enter to send a new request...')

...
