Hi and welcome to the forum.
To check the version of RPi.GPIO use this quick check python script:

Code: Select all

import RPi.GPIO as GPIO
print GPIO.VERSION

It should return version 0.5.11 :

Code: Select all

pi@raspberrypi ~ $ sudo python test2.py
0.5.11
pi@raspberrypi ~ $

If not run the following :

Code: Select all

sudo apt-get update
sudo apt-get dist-upgrade

That should get your system up to date. Then try your RPi.GPIO out again,

Thank you Texy.
I have the right version but the LED don't blink again.
Any ideas?

Please show us the wiring connections, and the program.

In the wiringPi example you are using gpio 18 (pin 12).

In the RPi.GPIO example you are using pin 18 (gpio 24).

Thank you joan.
Which number for the LED have i to use in my python script for GPIO 18?
bmou1999

There's more than one numbering system for the pins.

You can either use "board" numbering which is simply the physical pin number, so pin 18 is right hand side nine rows down. Or your can use "Broadcom" or "BCM" numbering which uses the names of the pins on the System on a Chip (SoC) they don't have a straight mapping to the physical pins.

Take a look at http://pi.gadgetoid.com/pinout which, hopefully, clears up your confusion.

Try running the
gpio readall
command which gives a picture of the pins and their current settings.

RPi.GPIO.setmode(RPi.GPIO.BOARD)
RPi.GPIO.setmode(RPi.GPIO.BCM)

Allows you to pick alternative numbering schemes.

Code: Select all

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BOARD)
GPIO.setmode(GPIO.BCM)

Choose ONE scheme and always use that in your code.

..it goes on for 1 second, then goes off. You need to add 1 second delay after the off, otherwise it will be on all the time, well to the naked eye anyway.
