Raspberry Pi Forums

I am trying to set up my Raspberry Pi camera module on my raspberry pi (c) 2011.12. I am first of all trying to get my pi to display me a preview of the camera image using python 3. I am following the tutorial on this page: https://www.raspberrypi.org/learning/ge ... worksheet/ And the code I am using is:
When I run it the shell gives me this error: I have tried running 'sudo raspi-config' and enabling the camera as well as enabling it in the the preferences menu, I rebooted the pi and tried it all again but it still gave me the same error!
Any help on this would be great!

That link is only applicable to Pi Zero, although the OP doesn't say exactly which board revision he has ( (c) 2011.12 implies an early board - my PiZero1.3 certainly has (c)2015 on it).

Try "vcgencmd get_camera". If supported is not 1 then you haven't enabled the camera. If detected isn't 1 then the GPU can't talk to the camera, so check and double check all connections.
I'd also recommend trying to use raspistill or raspivid for basic tests instead of your own otherwise untested Python app.

Where abouts would I enter this line of code in my python program? I am a bit of an amateur

You don't put that line in your Python program.

You type it in at the command line (LX Terminal) prompt, and then copy/paste the output into you next reply.

I have tried typing 'vcgencmd get_camera' and it gave me this:

supported=1 detected=2

I also have gone back and rechecked all the connections and rebooted the pi! Will have a look at raspistill and raspivid as well though...........

I was able to get my camera to work with raspistill then when I tried the following Python code (similar to yours)
-----------------------
from picamera import PiCamera
from time import sleep

camera = PiCamera()

camera.start_preview()
sleep(10)
camera.stop_preview()
-------------------------
I get a very similar traceback error to yours( see below) , did you resolve your camera problem? I have tried the debugging steps listed above and none work. THx
-----------------------------------

Something is very wrong if it has detected more than are supported. At a guess you've got a very old firmware revision. Try downloading the latest Raspbian image and trying again.

I have recently just reset my raspberry pi last wednesday and installed the latest edition on Raspbian OS!

"vcgencmd version" then to confirm.

I'm not aware of a way for detected to be greater than supported, so you've certainly found a quirky one.
