Uisng multiple phidget interfacekit in single python program

im trying to use multiple interfacekit pidget in a single python program here my coding but der the single phidget oly getting attache. and working.

#Basic imports
from ctypes import *
import sys
import random
#Phidget specific imports
from Phidgets.PhidgetException import PhidgetErrorCodes, PhidgetException
from Phidgets.Events.Events import AttachEventArgs, DetachEventArgs, ErrorEventArgs, InputChangeEventArgs, OutputChangeEventArgs, SensorChangeEventArgs
from Phidgets.Devices.InterfaceKit import InterfaceKit
from time import sleep
#Create an interfacekit object
try:
interfaceKit = InterfaceKit()
except RuntimeError as e:
print("Runtime Exception: %s" % e.details)
print("Exiting....")
exit(1)
def inferfaceKitAttached(e):
attached = e.device
print("InterfaceKit %i Attached!" % (attached.getSerialNum()))

def interfaceKitDetached(e):
detached = e.device
print("InterfaceKit %i Detached!" % (detached.getSerialNum()))

def interfaceKitError(e):
try:
source = e.device
print("InterfaceKit %i: Phidget Error %i: %s" % (source.getSerialNum(), e.eCode, e.description))
except PhidgetException as e:
print("Phidget Exception %i: %s" % (e.code, e.details))

#def interfaceKitInputChanged(e):
# source = e.device
# print("InterfaceKit %i: Input %i: %s" % (source.getSerialNum(), e.index, e.state))

#def interfaceKitOutputChanged(e):
# source = e.device
# print("InterfaceKit %i: Output %i: %s" % (source.getSerialNum(), e.index, e.state))

#Main Program Code
try:
interfaceKit.setOnAttachHandler(inferfaceKitAttached)
interfaceKit.setOnDetachHandler(interfaceKitDetached)
interfaceKit.setOnErrorhandler(interfaceKitError)
# interfaceKit.setOnInputChangeHandler(interfaceKitInputChanged)
#interfaceKit.setOnOutputChangeHandler(interfaceKitOutputChanged)
# interfaceKit.setOnSensorChangeHandler(interfaceKitSensorChanged)
except PhidgetException as e:
print("Phidget Exception %i: %s" % (e.code, e.details))
print("Exiting....")
exit(1)
print("Opening phidget object....")

try:
#interfaceKit.openPhidget(277983)
interfaceKit.openPhidget()
#interfaceKit.openPhidget(273506)
except PhidgetException as e:
print("Phidget Exception %i: %s" % (e.code, e.details))
print("Exiting....")
exit(1)

print("Waiting for attach....")

try:
interfaceKit.waitForAttach(10000)
except PhidgetException as e:
print("Phidget Exception %i: %s" % (e.code, e.details))
try:
interfaceKit.closePhidget()
except PhidgetException as e:
print("Phidget Exception %i: %s" % (e.code, e.details))
print("Exiting....")
exit(1)
print("Exiting....")
exit(1)
else:
interfaceKit.setOutputState(0,1);
interfaceKit.setOutputState(1,1);
interfaceKit.closePhidget()

Lesson learned!

phidgets are some sort of usb hardware.

You're more likely to get a reasonable answer if you ask your question at the phidgets web site, if they support customers.

Also, You've made me realize a new great reason to avoid

from module import *

It's about impossible to read your program because I need to know the entire name spaces of these modules. I certainly hope to remember this lesson and never ever again even consider import * .

You might have intended this python program?

Code:

#http://www.phidgets.com/


#Basic imports
from ctypes import *
import sys
import random
#Phidget specific imports
from Phidgets.PhidgetException import PhidgetErrorCodes, PhidgetException
from Phidgets.Events.Events import AttachEventArgs, DetachEventArgs, ErrorEventArgs, InputChangeEventArgs, OutputChangeEventArgs, SensorChangeEventArgs
from Phidgets.Devices.InterfaceKit import InterfaceKit
from time import sleep
#Create an interfacekit object
try:
    interfaceKit = InterfaceKit()
except RuntimeError as e:
    print("Runtime Exception: %s" % e.details)
    print("Exiting....")
    exit(1)

def inferfaceKitAttached(e):
    attached = e.device
    print("InterfaceKit %i Attached!" % (attached.getSerialNum()))

def interfaceKitDetached(e):
    detached = e.device
    print("InterfaceKit %i Detached!" % (detached.getSerialNum()))

def interfaceKitError(e):
    try:
        source = e.device
        print("InterfaceKit %i: Phidget Error %i: %s" % (source.getSerialNum(), e.eCode, e.description))
    except PhidgetException as e:
        print("Phidget Exception %i: %s" % (e.code, e.details))

#def interfaceKitInputChanged(e):
# source = e.device
# print("InterfaceKit %i: Input %i: %s" % (source.getSerialNum(), e.index, e.state))

#def interfaceKitOutputChanged(e):
# source = e.device
# print("InterfaceKit %i: Output %i: %s" % (source.getSerialNum(), e.index, e.state))

#Main Program Code
try:
    interfaceKit.setOnAttachHandler(inferfaceKitAttached)
    interfaceKit.setOnDetachHandler(interfaceKitDetached)
    interfaceKit.setOnErrorhandler(interfaceKitError)
    # interfaceKit.setOnInputChangeHandler(interfaceKitInputChanged)
    #interfaceKit.setOnOutputChangeHandler(interfaceKitOutputChanged)
    # interfaceKit.setOnSensorChangeHandler(interfaceKitSensorChanged)
except PhidgetException as e:
    print("Phidget Exception %i: %s" % (e.code, e.details))
    print("Exiting....")
    exit(1)

print("Opening phidget object....")

try:
    #interfaceKit.openPhidget(277983) 
    interfaceKit.openPhidget() 
    #interfaceKit.openPhidget(273506)
except PhidgetException as e:
    print("Phidget Exception %i: %s" % (e.code, e.details))
    print("Exiting....")
    exit(1)

print("Waiting for attach....")

try:
    interfaceKit.waitForAttach(10000)
except PhidgetException as e:
    print("Phidget Exception %i: %s" % (e.code, e.details))
    try:
        interfaceKit.closePhidget()
    except PhidgetException as e:
        print("Phidget Exception %i: %s" % (e.code, e.details))
        print("Exiting....")
        exit(1)
    print("Exiting....")
    exit(1)
else:
    interfaceKit.setOutputState(0,1); 
    interfaceKit.setOutputState(1,1);
    interfaceKit.closePhidget()
