Topic: Is this I2C OLED broken? (Read 92 times) previous topic - next topic

Hi there,
   
            I recently bought a small i2c OLED display and after a little tinkering I managed to
get it displaying. For some reason though what ever I try to display on it, it doesn't change
only a few pixels on the left hand side seem to move. It seems to me this display is full of
dead pixels and I should return it, but I though I best double check first.

I've attached my wiring diagram(note this is not the model of pled I have) and a picture of
the screen below, I couldn't seem to find a data sheet anywhere. I'm using the GOFi2cOLED
library to interact with it.

Thanks to anyone who can confirm my fears.

You should look for a confirmation by another library (maybe u8glib, which should work out of the box with your setup).
Note that this OLED might contain two different (incompatible) controllers: SSD1306 or SH1106. More difficult: These OLEDS are often sold as SSD1306, although they contain the SH1106 controller.

Edit: I had a look at the GOFi2cOLED library. It got derived from the Adafruit lib for the SSD1306. So maybe you should try u8glib with the SH1106 constructor. I assume this is a SH1106 display.
