我的目标是 运行 通过 Python 步进器，但是 angular 速度和度数等值是由用户通过 GUI 输入的
My goal is to run a Stepper through Python, but the values such as angular velocity and degrees are inputted by user through GUI
我遇到了 Tkinter window 不显示其内容以及将用户输入的数据存储到步进参数中的问题。我在不同的代码中找到了 运行 Tkinter 和步进器，它工作了。但我无法整合所有内容。这是我的代码：
import time
from tkinter import *
from pymata4 import pymata4
top = Tk()
top.geometry("450x300")
pins = [8,9,10,11]
board = pymata4.Pymata4()
board.set_pin_mode_stepper(num_steps, pins)
num_steps = Label(top, text="Steps").place(x=40, y=60)
angular_velocity = Label(top, text="Angular Velocity").place(x=40,y=100)
submit_button = Button(top, text ="Submit").place(x=40,y=130)
num_steps_input_area = Entry(top, width=30).place(x=180,y=60)
angular_velocity_input_area = Entry(top, width=30).place(x=180, y=100)
angularvelocity = angular_velocity_input_area.get()
numsteps = num_steps_input_area.get()
while True:
board.stepper_write(angularvelocity, numsteps)
time.sleep(1)
board.stepper_write(angularvelocity, numsteps)
time.sleep(1)
top.mainloop()
我不得不移动很多东西。由于我不熟悉原始代码的所有上下文，因此可能仍然存在一些问题。但是，希望它足够好，您可以看到如何实现您的目标。
我查看了 pymata4 模块，发现您的操作存在一些问题。

top.geometry("450x300")
pins = [8,9,10,11]
board = pymata4.Pymata4()
# These variables need to be declared to be in the global space.
total_steps = 512 # Total number of steps per revolution of the stepper motor.
motorspeed = 0 # The library does not use angular velocity, but speed.
numsteps = 0 # To change direction use negative int, according to the module documentation.
complete = False # I added this to show how to stop running.
def actuate():
global motorspeed, numsteps, complete
board.stepper_write(motorspeed, numsteps)
if complete:
pass
else:
top.after(1000, actuate) # This will run actuate after 1000 ms
def set_input():
global pins, motorspeed, numsteps
motorspeed = motor_speed_var.get() # run .get() on IntVar object instead
