OLED display not working
-
Hi,
I received my Omega 2+ this week. Upgraded the firmware and installed the console. All looking good.
But no matter what I try, I can't get the OLED display to work. I've tried it both from the console and from the command line. All commands seem to be accepted without error, but the display always remains dark. Nothing is ever displayed.
Can anybody suggest anything else I can try?
Many thanks.

Can you please post a link to the tutorial/manual you used to get so far?

I used this tutorial for connection:
https://docs.onion.io/omega2-docs/oled-expansion.html
... and this tutorial for operation:
https://docs.onion.io/omega2-docs/using-oled-expansion.html#using-oled-expansion
For example, this command:
oled-exp -i write "Hello world"
...has no discernable effect on the display.

@Chris-Allen You might want to install the packages in case they didn't install properly.
Type opkg list | grep oled
and then install any packages that it might need such as the driver. You might also want to initialize it with oled-exp -i then try writing to it.
-
This error might be because of the C-Library ... as i did read it changed from onion1 to onion2. Look after a pure python tutorial to use the OLED Display anyway for the moment.
You could check out the wiki.onion.io by avoiding using the c-library.

did you power the display on?
-
It works fine for me from the command line, no need to install any libraries.
I did run oupgrade when I first powered up the Omega2 though, maybe that is what it needs?
The display has a power down mode, this should switch it on:
oled-exp power onIt worked fine for me without that though.

I've tried both command line and web based but Oled is not displaying anything.
I have an Omega2+ with Firmware 0.1.10 b160
I have tried the following but with no success ...
oled-exp -i
oled-exp power on
oled-exp write "hello"
Also, 'opkg list | grep oled' shows that Oled driver is installed.
