OLED Dispaly Issues

Hi,

I have a i2C OLED that I cannot seem to display even an example sketch on correctly.
Attached is the image that is displayed. I have tried various examples and I keep getting the same strange type of display with most of the lower section pixelated with an image of sorts at the top.

I have attached the code I am using.

Any assistance would be great.

Hi,

Please read the first post in any forum entitled how to use this forum.
http://forum.arduino.cc/index.php/topic,148850.0.html then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.

Thanks.. Tom.. :slight_smile:

Hi.
I have down loaded your code and it works for me.
However your picture shows your OLED screen physically skewed on the breakout board.
I would guess your screen is damaged.

I think Tom nailed it spotting physical damage.

what size pull-up resistors you using in theI2C pins ?

Most probably you're just using wrong library for that display. Try using SH1106 instead of SSD1306. I struggled with that same problem a fair bit before i realized my screen wasn't what it was advertised to be..

I don’t use any pullups, just playing with two I2C displays, still perfect without pullups.
I’m using two different clones of the 128x64, I can measure 10K pullups in one and 15K on the other.

That does not work for a code that is over 9000 characters.

I know, but how many noob codes are that big, it needs mentioned in the help text?
