I recently purchased a 1.3" 128x64 OLED SSD1306 : http://www.adafruit.com/products/938
I am controlling it with an Arduino Nano (AT328 version).
I loaded up the libraries and the example code, compiled, uploaded, and it starts right up! But there seems to be an issue with my display. The top half of the display (I think rows 32-63?) alternate working and not working. I have checked the library code myself, and I've even white-filled the screen, and sure enough every other row is black, and I cannot get the pixels in those rows to light at all. I have tried the different Common-mode pin configuration, and nothing seems to work. The bottom half of the display seems to work flawlessly. The top half only every other row works. My soldering job seems pretty good and I was experiencing this issue before I began soldering when I just had it in a header for testing. The effect is always present, even on the splash screen, which breaks up the top half of the Adafruit Industries logo. Do I have a bad unit or am I missing something? Thanks ahead of time.
P.S.: I can send pictures when I am home again (at work now).
P.P.S.: I made sure it is actually using the settings for the 128x64 variant.
