ok so i removed both the oled display and the usb expansion. Then did a factory reset. reinstalled the usb expansion, and keyed in the scripts. shut down the onion, and reinstalled the oled display. rebooted and ran the scripts.
I got the correct display on the oled.

I think I read somewhere that there is a bug in the oled control library that is slated for a future firmware update with the error 'write" I got the error, but the script works. Thanks for the help

I have considered flashing the whole thing and starting from scratch to get a clean install. Perhaps there is something there that is wonky and just needs to be reinstalled?

in the /usr/lib/python2.7 directory I have a json directory installed, then a urllib.py file
How do I check which version these are? I opened the urllib.py file and there is not version information included. Are they correct since they are installed in the python2.7 directory? I did not specifically install these.

package python (2.7.9-5) installed in root is up to date.
root@Omega-2044:/# opkg list-installed | grep -i python

I installed the full version of python. I wonder if it is looking for those modules in some other directory? they appear to be installed, but still get the errors.

As an update, I am using the sample on the wiki page Oled Expansion. Here is the code:

#!/usr/bin/env python
import urllib
import json
myfile = open('/usr/bin/ticker.txt', 'r')
rg=myfile.read()
site="http://www.google.com/finance/info?q="+rg
jfile=urllib.urlopen(site)
jsfile=jfile.read()

jsfile=jsfile.replace("\n","")
jsfile=jsfile.replace("/","")
jsfile=jsfile.replace("]","")
jsfile=jsfile.replace("[","")
a=json.loads(jsfile)
ticker=a['t']
price=a['l_fix']
info=ticker+":"+price
print info

So the errors I get when attempting to run this are Import: not found
This is for both the lines calling for urllib and json to be imported into the environment. This fails I am guessing because I do not had urllib or json either installed, or in the correct location for the command to find them. Any help?

I am trying to learn using the sample stock ticker project on the wiki page. I have the oled expansion correctly installed, I can use the console and write to the oled. However when I try to run the stock_script.py I get an error on the import of urllib in line 4 and error on import of json on line 5
import: not found

I am attempting to understand where these would be imported from so I can make certain that I have the correct modules installed. I did expand the storage to the usb storage and installed the full python environment.
Any help would be appreciated

I am able to ssh into the Omega, so that solves my initial problem. thanks

I have a US 105 USB keyboard and was using the terminal editor from the Onion Console. The '-' '_' key does not work there.
I will attempt to connect using ssh and see what happens. Thanks

Need a little help here. When I use the terminal editor in Onion console, I cannot type an underscore " _ ".
How can I map that character to the Omega?
