RPi.GPIO in a module #49

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 

What steps will reproduce the problem?

1. I try to create a module "myinit_GPI"
   and then import the module -  import mymodule
   In this simple module

   def myinit_GPI():
       GPIO.setmode(GPIO.BCM)
       GPIO.setwarnings(False)

       GPIO.setup(2, GPIO.OUT)
       GPIO.setup(3, GPIO.OUT)

       GPIO.output(2,1)
       GPIO.output(2,0)
       return

2.  From the main prog I like to init ... 

3.  #!/usr/bin/python
    import RPi.GPIO as GPIO
    import mymodule    

    mymodule.myinit_GPI()

4.  I revieved an error

    mymodule.myinit_GPI()
    AttributeError: 'module' object has no attribute 'myinit_GPI'

    QUE !?!?!?

I use PYTHON - v2.7.3 And Raspian 2013-07-26-wheezy-raspbian.zip
I'm a beginner of Raspian and also a Python beginner ...

Best Regards  Peffag

More Info :  If I put all code in the same main program it work fine !!!
             The problem is only if I use import of mymodule.myinit_GPI()
             If I add som mymodule.simple() it works fine.
             "simple()
             "print "Hi"
             "return

This is not an issue with RPi.GPIO.  It is an issue with your code.

To fix your problem, add the line:
import RPi.GPIO as GPIO
at the beginning of mymodule.py

You need to import every dependency of a module at the top of a module, just 
like you would in your main program.
