OLED SPI weird behaviour

Hi,

I wired this OLED SPI display https://www.banggood.com/0_96-Inch-White-IIC-I2C-OLED-Display-Module-12864-LED-For-Arduino-p-932606.html to my Arduino Duemilanove (original).

I’m using the U8g2 library and there’s a weird behaviour because There’s a column of pixels always on and another column instead is missing. Please look at the photo.

What do you think? It could be a hardware issue? I did a mess when I soldered the pins, so it wouldn’t be a surprise if I ruined it.

I also tried to rotate the display and the column is still there so I don't think this is a software issue.

I think it should be reasonably obvious that rotating the display - being a software function - does not in any way indicate it is not a software problem, which it most likely is. :astonished:

It just might help had you provided a photo - but you did not. You provided a web page instead. Let me see ...
