Pibrella + RPI線程停止

Question

我正在寫一個腳本，一旦Pibrella上的按鈕被按下，就會每隔10秒發送一封電子郵件。我希望它再次按下按鈕時停止。

因此，例如，第一次按下時，它每隔10秒發送一封電子郵件。然後第二次，它停止線程。

這是我目前的代碼，有人可以告訴我我在哪裏做錯了嗎？

import pibrella, signal 
import threading 
import time 
import smtplib 

server = smtplib.SMTP("smtp.gmail.com",587) 
server.ehlo() 
server.starttls() 
server.ehlo() 

server.login("email@gmail.com", "EmailPassword") 

isPressed = 0 

def pressed(pin): 
    global isPressed 
    if isPressed == 0: 
     isPressed = 1 
     sendMail() 
    else: 
     pibrella.light.off() 
     t.cancel() 
     isPressed = 0 

def sendMail(): 
    pibrella.light.pulse() 
    server.sendmail("email@gmail.com", "receiver@gmail.com", "Hello World") 
    t.start() 

t = threading.Timer(10, sendMail).start() 

pibrella.button.pressed(pressed) 
pibrella.pause() 

server.close() 

我現在正在獲取的錯誤發佈在下面。請注意，電子郵件確實正在發送。

代碼用於發送電子郵件（從我Github上）

import subprocess 
import smtplib 
import socket 
from email.mime.text import MIMEText 
import datetime 
#account info 
to = 'example@gmail.com' 
gmail_user = 'example@gmail.com' 
gmail_password = 'your_password' 
smtpserver = smtplib.SMTP('smtp.gmail.com', 587) 
smtpserver.ehlo() 
smtpserver.starttls() 
smtpserver.login(gmail_user, gmail_password) 
today = datetime.date.today() 
arg='ip route list' 
p=subprocess.Popen(arg,shell=True,stdout=subprocess.PIPE) 
data=p.communicate() 
split_data=data[0].split() 
ipaddr=split_data[split_data.index('src')+1] 
my_ip='your_message' 
msg=MIMEText(my_ip) 
msg['Subject']= 'the_subject' 
msg['From']= gmail_user 
msg['To'] = to 
smtpserver.sendmail(gmail_user, [to], msg.as_string()) 
smtpserver.quit()
