DANKE

Guten Abend,

ich habe probleme python example_enumerate.py fuer "Industrial Digital In 4" an meinem Raspberry Pi(Raspbian) ich habe den daemon und den viewer genau so installiert wie beschrieben und es läuft beides.

auch "alle"nötingen python packete hinzugefügt ( example_enumerate.py läuft ja)

jedoch kann ich nichts auslesen ...

# Read out values as bitmask

    value = idi4.get_value()

example_enumerate.py zeigt alles richtig an

pi@raspitest2 ~/TF/examples $ python example_enumerate.py

-------------------------------------------------

in "example_simple.py" habe ich die UID

UID = "mWp" # Change to your UID

eingeragen:

-------------------------------------------------

pi@raspitest2 ~/TF $ cat example_simple.py

#!/usr/bin/env python

# -*- coding: utf-8 -*-

HOST = "localhost"

PORT = 4223

UID = "mWp" # Change to your UID

import time

from tinkerforge.ip_connection import IPConnection

from tinkerforge.bricklet_industrial_digital_in_4 import IndustrialDigitalIn4

if __name__ == "__main__":

    ipcon = IPConnection() # Create IP connection

    idi4 = IndustrialDigitalIn4(UID, ipcon) # Create device object

    ipcon.connect(HOST, PORT) # Connect to brickd

    # Don't use device before ipcon is connected

    # Read out values as bitmask

    value = idi4.get_value()

    print('Value: ' + str(bin(value)))

    raw_input('Press key to exit\n') # Use input() in Python 3

    ipcon.disconnect()

das ist die fehler meldung ...
