Raspberry Pi、tkinter、トリガ時のスクリーンカウンタon

Question

私はGPIOがトリガされたときに画面の一番下にキルボタンとカウンタを表示するシンプルなスクリプトを持っています。カウンターを画面中央に表示したいです。しかし、実際には、 "殺す"ボタンを押して、その下にカウンタを表示します。カウンターを画面中央に表示するにはどうしたらいいですか？

root.mainloop() 


# Start a loop that never ends 
#while True: 
    # Put anything you want to loop normally in here 
    # sleep(.1);   # Sleep for a full minute, any interrupt will break this so we are just saving cpu cycles.

後の画面ラベルにpack()を使用しないでください：

label = tk.Label(sp, fg="green") 
label.place(relx=0.5, rely=0.5, anchor=CENTER) 

またcounter_label機能を

counter = 0 
def counter_label(label): 
    def count(): 
    global counter 
    counter += 1 
    #m = Label(text=str(counter)) 
    #m.pack(side=TOP, expand=YES) 
    #m.config(bg="#3366ff", justify=CENTER, font=("calibri", 29)) 
    label.config(text=str(counter), bg="#000000", justify=CENTER, font=("calibri", 29)) 
    count()
