Threading Megapi Python

#1

Hello I wanted two functions parallel with threading run however functioned the night since already in Megapi a threading runs.
How can I run multiple functions in parallel?

Megapi import
from megapi import *
import time, os, random


from threading import Thread



global stopp_turn
global time_stopp


def onRead(v):
    global Ultraschall;
    Ultraschall = v;
    #print "distance:"+str(Ultraschall)+" cm";
    

   # So lange stopp = 0 arbeitet dieser Thread in der
   # Endlosschleife.
def control():
    global stopp_control
    global time_stopp
    stopp_control = 0
    turn_degree = 0
    bot = MegaPi()
    bot.start()
    sleep(1);
    while stopp_control == 0: 
            sleep(1);
            bot.encoderMotorRun(1,100);
            bot.encoderMotorRun(2,100);
            sleep(1);
            bot.encoderMotorRun(1,0);
            bot.encoderMotorRun(2,0);
            if time_stopp < time.time():
                stopp_control = 1
                print "Programm Ende";
            

def sensoren():
    global stopp_control
    global time_stopp
    stopp_control = 0
    bot = MegaPi()
    bot.start()
    sleep(1);
    while stopp_control == 0:
        bot.ultrasonicSensorRead(7,onRead);
        print "Thread Sensor Run";
        sleep(1);
        
        
    
laufzeit=input("Bitte die Zeit in Minuten eingeben die das Roboter-Auto fahren soll: ")    
time_stopp = laufzeit*60 + time.time()

t_control = Thread(target=control)
t_sensoren = Thread(target=sensoren)

t_control.start()
t_sensoren.start()

Can someone take a sample post how I can let the robot drive with Python over an ultrasonic sensor?
I just can not get it running

What is the error you are getting?

@roboterpi - Hi, were you able to use the Ultrasonic Sensor with Python and Raspberry Pi ?
Thanks again.
