Plugging in PiOLED causes major problems in Pi Zero W

Post by bronsoon »

So I'm trying to use a PiOLED to show stats for my PiHole setup on my Pi Zero W. I've followed this
https://learn.adafruit.com/adafruit-pio ... y-pi/usage
and this
https://learn.adafruit.com/adafruits-ra ... guring-i2c
guide so far. But after I run "sudo raspi-config" and enable I2C support, then reboot, I run into a major problem when I plug in my PiOLED. As soon as I plug it in (using the 6 leftmost pins) any command returns the error "-bash: /usr/bin/sudo: Input/output error". I can exit the SSH session (I'm still connected) but I can't reconnect via SSH until I manually restart the Pi by unplugging it and plugging it back in. When the Pi reboots and I can reconnect, it acts normally, but the command "sudo i2cdetect -y 1" shows that no I2C addresses are used despite the PiOLED being plugged in.

Any help would be appreciated. Thanks!

Post a photo showing your hardware and connections please. 800x600 images usually work best.

Hi, sorry for the long delay. Here's my setup. As simple as it gets, really.

I don't see anything out of the ordinary there.

Do you happen to have another RasPi you can use to test the PiOLED?

No, I don't have another Pi but I do have an Arduino Uno. I don't know when I'd have the time to wire it up for I2C though

I just took a closer look at the photo above, and saw what might be a problem in the upper-right corner of the OLED:

Check to see if the glass has broken or chipped there. The transparent conductive traces that run to the OLEDs go around that corner, so a break there will kill the whole display.
