我的按钮将启动并停止从外部模块调用的功能

Question

通过仅放置R.Loop（），该功能在GUI内调用时起作用。但是，它不会单击按钮。我尝试使用.configure，但这不起作用。该模块在源代码内部也可以单独工作。我以为我在某个地方听说TKINTER不喜欢Globals，但我不确定。

    #creating a global variable for running loop
    global Run
    Run=False
    
    #begin GUI CODE
    
    main = tk.Tk()
    main.title('REGENERATOR')
    main.geometry('800x800')    
    
    ...
    
    #THIS IS THE CALL OF FUNCTION SETUP
    
    running_setup=R.setup()
    
    #Funtion to initialize the motor
    
    def motor():    
        if Run(True):
            R.loop()
    
    #This is the start button
    
    def startmotor():   #Function to start motor
        global Run
        Run = True
        #Button_run.configure()
    
    Button_run=Button(frame5, text="run", command=lambda:startmotor, bg="white", fg="black", padx=5, pady=5, font=("Times", 16))
    Button_run.grid(row="2", column="0")        
    
    #This is the stop button
    
    def stopmotor():
        global Run
        Run = False
        #Button_stop.comfigure()
    
    Button_stop=Button(frame5, text="stop", command=lambda:stopmotor,  bg="white", fg="black", padx=5, pady=5, font=("Times", 16))
    Button_stop.grid(row="2", column="1")
