如何将'Ctrl+C‘映射到RaspberryPi上的按钮？

import RPi.GPIO as GPIO
import os
import time
import uinput

# 定义按钮连接的GPIO引脚
BUTTON_PIN = 17

# 初始化GPIO设置
GPIO.setmode(GPIO.BCM)
GPIO.setup(BUTTON_PIN, GPIO.IN, pull_up_down=GPIO.PUD_UP)

# 创建uinput设备对象
device = uinput.Device([uinput.KEY_LEFTCTRL, uinput.KEY_C])

# 按钮按下事件的回调函数
def button_pressed(channel):
    # 模拟按下'Ctrl+C'键盘事件
    device.emit(uinput.KEY_LEFTCTRL, 1)
    device.emit(uinput.KEY_C, 1)
    time.sleep(0.2)
    device.emit(uinput.KEY_LEFTCTRL, 0)
    device.emit(uinput.KEY_C, 0)

# 监听按钮的按下事件
GPIO.add_event_detect(BUTTON_PIN, GPIO.FALLING, callback=button_pressed, bouncetime=200)

# 保持脚本运行
try:
    while True:
        time.sleep(1)
except KeyboardInterrupt:
    GPIO.cleanup()
