PiOLED Not Displaying

by jljozsa on Fri Mar 23, 2018 12:42 pm

Hello - first let me apologize if I am posting in the wrong place; I'm very new to forums.

I purchased a PiOLED on 3/15/2018 (order # 1709982-9456734411) and I cannot get the display to work.

I built a Pi-Hole and I've been following this guide (https://learn.adafruit.com/adafruits-ra ... guring-i2c) to get i2c configured, When I get to the step to enter 'sudo i2cdetect -y 1', it isn't detecting my PiOLED.

I've tried soldering/re-soldering the GPIO header, I've tried a Hammer Header Male Solderless Raspberry Pi Connector, I've tried on 3 different Pi Zeros - all getting the same result. When testing, I was able to get a 3.5 inch PiTFT display to work.

Is there something I'm missing, or is it possible that I received a dud display?

Thanks!

Sounds like you've got various GPIO header styles - solder, hammer, etc. The PiOLED works on none of them (correct?). How about the PiTFT - did it work on all 3 Pi's? If it did, pick the one you think has the best GPIO headers installed. If not, then let's use the one where it did work.

Post a photo of the Pi Zero you're trying to use showing the GPIO header installation (so I can check either the soldering or how well the hammer header worked). Also post a photo showing how you are trying to use the PiOLED.

Ok - here is the pi and the solder job. This is the 4th motherboard I've tried it on; my soldering isn't great but it does the trick for everything else.

Sorry for delayed response. I should've asked for clarification on this:
When I get to the step to enter 'sudo i2cdetect -y 1', it isn't detecting my PiOLED.

Can you post the actual output you get from running that command.

Yep. That's nothing. Let's replace it. Send an email to support@adafruit.com with a link to this thread and they can help get you a new Pi OLED.

I'm still a little concerned about the soldering in the photo you posted. But you say a 3.5 inch PiTFT display worked and you tried various Pi Zero's so it could be the display. Please report back if the replacement works.

Success!! Plugged the new PiOLED in, booted it back up, ran sudo i2cdetect -y 1 and voila:
