按下键盘输入时PYTHON程序运行（执行）

Question

您好，我有一个使用Slushengine电机驱动程序运行几个电机的简单python项目。我已经制作了示例程序（如下面的代码所示），但是现在我想让我在按下键盘（输入）上的键（例如ENTER键）时使电动机运行。然后，当我按下另一个键时，我希望程序停止。from inputs import get_keyimport RPi.GPIO as GPIOimport Slushimport mathimport timefrom time import sleepb = Slush.sBoard()m = [Slush.Motor(0), Slush.Motor(1), Slush.Motor(2), Slush.Motor(3)]m[0].setMaxSpeed(150)m[1].setMaxSpeed(150)m[2].setMaxSpeed(250)m[3].setMaxSpeed(150)m[0].setCurrent(150, 150, 150, 150)m[1].setCurrent(100, 100, 100, 100)m[2].setCurrent(150, 150, 150, 150)m[3].setCurrent(100, 100, 100, 100)GPIO.setmode(GPIO.BCM)GPIO.setup(18, GPIO.OUT)pwm = GPIO.PWM(18, 100)pwm.start(0)GPIO.output(18, True)pwm.ChangeDutyCycle(1)sleep(0.5)m[1].goTo(750)time.sleep(3)m[0].goTo(750)time.sleep(3)pwm.ChangeDutyCycle(99)sleep(1)当检测到按键时，我需要执行此代码。pwm.ChangeDutyCycle(1)sleep(0.5)m[1].goTo(750)time.sleep(3)m[0].goTo(750)time.sleep(3)pwm.ChangeDutyCycle(99)sleep(1)

Answer 1

它不是已经显示在PyPI中了吗？

from inputs import get_key

def key_input():

    while 1:

        events = get_key()

        for event in events:

            print(event.ev_type, event.code, event.state)

if __name__ == '__main__':

    key_input()

Answer 2

这样对吗？？对不起，我还不清楚

from inputs import get_key

import RPi.GPIO as GPIO

import Slush

import math

import time

from time import sleep

b = Slush.sBoard()

m = [Slush.Motor(0), Slush.Motor(1), Slush.Motor(2), Slush.Motor(3)]

m[0].setMaxSpeed(150)

m[1].setMaxSpeed(150)

m[2].setMaxSpeed(250)

m[3].setMaxSpeed(150)

m[0].setCurrent(150, 150, 150, 150)

m[1].setCurrent(100, 100, 100, 100)

m[2].setCurrent(150, 150, 150, 150)

m[3].setCurrent(100, 100, 100, 100)

GPIO.setmode(GPIO.BCM)

GPIO.setup(18, GPIO.OUT)

pwm = GPIO.PWM(18, 100)

pwm.start(0)

GPIO.output(18, 1)

while 1:

    events = get_key()

    for event in events:

        if event.code == 'KEY_ENTER':

            pwm.ChangeDutyCycle(1)

            time.sleep(1)

            m[1].goTo(750)

            time.sleep(3)

            m[0].goTo(750)

            time.sleep(3)

            pwm.ChangeDutyCycle(99)

            time.sleep(1)
