Confused about GPIO

Hi all,

I recently got a Raspberry pi and am loving it so far. The only problem I have encountered is GPIO. If I understand correctly, I need to download something to use them in python. I have tried everything that i could find without success:

$ sudo python

>>> import RPi.GPIO as GPIO

(which came up with something about the file not existing)

and

$ wget http://pypi.python.org/packages/source/R/RPi.GPIO/RPi.GPIO-0.1.0.tar.gz

(which said that the website wasn't available or something)

I have tried updating/upgrading the software with

$ sudo apt-get update

(which I think came up with some errors)

and

$ sudo apt-get upgrade

(seemed to work)

What should I do? Am I doing something wrong? I "inherited" the Raspberry pi, so i don't know when it was bought and it came with a preinstalled sd card so i'm not 100% sure what it is running but I think raspbian.

Many Thanks,

Kelan

Kelan,

Are you still needing some help with your Pi?

There's a great deal of information about RasPi GPIOs at the RasPi Hardware Wiki: http://elinux.org/RPi_Low-level_peripherals

It should be accurate for a RasPi Model A/B and has some updates for A+/B+. I don't think it's been updated for RasPi 2 -- I think the only change from B+ is that the peripheral registers are at 0x3F000000 instead of 0x20000000.

Thanks for all your comments, I tried:
sudo apt-get update
sudo apt-get install python-dev
sudo apt-get install python-rpi.gpio
in the LXTerminal without much success

(I'm not sure how good the pictures will turn out)
Any other suggestions?

I am thinking of getting a new SD and starting from scratch...

You don't really need a new SD card.. You can format the one you have and start fresh.

sudo apt-get update
sudo apt-get install python-dev
sudo apt-get install python-rpi.gpio

That should install the packages for you
