oled-exp -i write "hello"

But I can't get the stock ticker to work. I get the following error:

root@Omega-****:~/oled-stock-ticker# python main.py
Traceback (most recent call last):
File "main.py", line 4, in <module>
import oledDriver
File "/root/oled-stock-ticker/oledDriver.py", line 1, in <module>
from OmegaExpansion import oledExp
ImportError: cannot import name oledExp

I can't find any information on this error. I've tried installing the drivers and it did not help.

OK I was able to fix this problem by updating:

opkg upgrade libonioni2c pyOnionI2C
opkg install python-light pyOledExp

But now there is a new error

Initializing display
Traceback (most recent call last):

File "/usr/lib/python2.7/json/decoder.py", line 382, in raw_decode
raise ValueError("No JSON object could be decoded")
ValueError: No JSON object could be decoded

I have not edited the json yet, so it should be formatted correctly.
I'm still learning how to use python, so some of this is confusing to me.

What should I try next to fix this error?

I'm a bit nervous about botching it up.

If this fails is there anyway to just erase everything on the onion and start over?

Thank you

Really stuck at this point.

Stock Ticker is another example of "It worked at previously!" @Lazar-Demin

I made the newsfeed work instead and will adapt that into to train time display for my husband.

Good to know I wasn't just messing up.
