Question

我试图从函数调用中断一个while循环。 blink来自脚本 control.py 。这是从脚本 main.py 运行的。我的目的是调用闪烁功能并在调用函数关闭时停止闪烁。

我尝试使用调用x =＆＃34; 0＆＃34; 并在off函数上调用X

Control.py

from ConfigParser import SafeConfigParser 
from SimpleXMLRPCServer import SimpleXMLRPCServer
import RPi.GPIO as GPIO 
from time import sleep as sleep
import xmlrpclib 

#setup settings
parser = SafeConfigParser() 
parser.read('/home/pi/ns/led.conf') # get GPIO Pin & Run time settings
proxy = xmlrpclib.ServerProxy("http://localhost:8000/") #Set host for LCD Screen


GPIO_PIN = int(parser.get('settings', 'GPIO_PIN'))#Set GPIO pin
run = float(parser.get('settings', 'run_time'))#set run time

def gpio():
 return GPIO_PIN 
int(parser.get('settings', 'GPIO_PIN'))#Set

def setup_gpio():
    GPIO.setmode(GPIO.BOARD)
    GPIO.setwarnings(False)
    GPIO.setup(GPIO_PIN, GPIO.OUT)
def on():
    try:
        proxy.normal()
        GPIO.output(GPIO_PIN, GPIO.HIGH)
        proxy.stat_ok()
    except Exception as e:
        print e
        GPIO.cleanup()
        notify(e)
def off():
    try:
        proxy.normal()
        GPIO.output(GPIO_PIN, GPIO.LOW)
        proxy.stat_ok()
    except Exception as e:
        print e
        GPIO.cleanup()
        notify(e)
def blink():
    try:
        proxy.normal()
        while true:
         GPIO.output(GPIO_PIN, GPIO.HIGH)
         sleep(run)
         GPIO.output(GPIO_PIN, GPIO.LOW)
    except Exception as e:
        print e
        GPIO.cleanup()
        notify(e)
try:
 server = SimpleXMLRPCServer(("localhost", 8001), allow_none=True)
 print "Control Listening on port 8001..."
 proxy.control_on() 
 server.register_function(on) 
 server.register_function(off) 
 server.register_function(blink) 
 server.serve_forever()
except Exception as error:
    print error
    proxy.control_off()

main.py

import xmlrpclib 
control = xmlrpclib.ServerProxy("http://localhost:8001/")
while True:
    cont = raw_input("Please select (O)n, (B)link, or O(F)F :")  
    if cont == "O":
     control.on() # LED ON
    elif cont == "F":
     control.off() # LED OFF
    elif cont == "B":
     control.blink() # LED BLINK
    else:
     print "please try again"

从另一个脚本中断一个while循环
