Garbage/Lines on Side of OLED Expansion
-
Is there something wrong with my OLED Expansion. The right side of the OLED display shows lit up pixels/lines even after clearing or initializing the screen... Thanks in advance for any help!
-
@Joshua-Rhykerd Hmm, that's interesting. I've never seen something like this before. What happens when you try to display things around those pixels? And do they respond to the inverse function?
-
It seems to mess up the display. "Test Test" on the left are shown one right above the other. "Test Test Test" on the right should be displayed the same way, but they are being broken up as a result of those already lit up pixels.
-
Also the lit up pixels/lines are still there on the inverse.
-
@Joshua-Rhykerd I had a similar issue with my OLED display. I found that I could completely clear my screen if I enabled scrolling so that the inverted pixels were somewhere in the middle of the screen, then I cleared the screen.
Hope this helps.
-
@Samuel-Ellicott You are the man! That worked exactly as explained and all the garbage pixels/lines have been cleared. Thanks!
-
@Joshua-Rhykerd While for the life of me I can't find it now, but I seem to remember that recently @Lazar-Demin posted something about updates to the OLED libraries associated with this. Do you have the latest release installed on your Omega?
-
@Kit-Bishop I do have the latest release installed on my Omega. Thanks for your input.
-
@Joshua-Rhykerd All good - just trying to think of things that might cause the problem - sorry I couldn't be of more help
-
I thought this problem was resolved in thanks to @Samuel-Ellicott's suggested solution, but it seems that it was only a temporary fix. When powered off and back on again the dots/lines seem to reappear?
-
@Joshua-Rhykerd It's probably not an issue with the hardware. We are working on our end to identify the issue in the driver.
-
Yeah, it's probably not the hardware. When my Omega arrived and there was still no driver for the OLED my display didn't have these lines.
After the upgrade that introduced the driver I noticed this on my display as well. If I load a 128x64 image the "garbage" is cleared.
-
Yeah, definitely not hardware. This issue showed up with the latest firmware release where @Lazar-Demin was working on some other issues with the OLED (discussed here).
-
yep, it's a driver issue. I'll be looking into it tonight!
-
@Scott-Smith, @fader, @Joshua-Rhykerd: please pickup b246 and try it out again, I think I've fixed the nagging issues but I appreciate your help in testing.
Run
oupgrade -l -fon the command line to grab b246.
Or you can try grabbing the latestoled-exppackage from the Onion package repo:opkg update opkg --force-reinstall install libonionoledexp oled-expI've done testing on my end but let me know if there are any issues on your end!
-
@Lazar-Demin Looks good on my end. Thanks for the fix!
-
works perfectly ... thanks !!!
