Adafruit Monochrome 1.3" 128x64 OLED


Can anyone help with a problem i’ve got with the above display

I have this display connected to a pi3 running raspbian stretch

I have soldered the 2 jumpers noted on the rear to enable i2c
The display shows as 0x3d with 1. sudo i2cdetect -y 1

I edited the python code accordingly and
having followed the examples below I am only seeing random pixels shown

Has anyone seen a similar issue and if so how did you overcome it?


hi,i dont have this adafruit product ,but i do have there captive touch hat, and it was treat to get working … there is a lot to do in that link and if its not all done and in correct order i think it can cause issues with the display working properly


Making a typo and not noticing you did it will mess you up too. Been there done that.
I’d start over with a clean new Raspbian Image, then run through the tutorial one more time, paying close attention to what you see on screen

And double check your wiring / jumper wire hookup.


Thanks everyone for the hints and tips. The final cause was tracked down to a dry joint on the rst pin

Anyone else experiencing random pixels in future, I would say the unit has not been successfully initialised. The reset operation is key to its operation
