I have one of these http://www.buydisplay.com/default/color-oled-display-module.html color 128x128 oled displays. The adafruit site the demo uses a micro SD card to store the bmp image. If there is enough room on the micro to store a color image instead of using sd card then a BMP to array converter would be great. LCDassistant http://en.radzio.dxp.pl/bitmap_converter/ works great for the smaller mono displays that I use.

128*128 pixel with 2 bytes per pixel will be 32K bytes. This is exactly the flash rom size of the Arduino Uno. It might fit on the Mega, but accessing the bitmap could be difficult. Arduino Due should work.

How did you connect the display? This ZIF connector is very small... Additionally you need all these extra components (caps, resistors, etc). Did you face any problems connecting this display? The pure OLED from buydisplay.com has  a good price. Together with a PCB for the Arduino, price is 5 times higher.

BuyDisplay is where I grabbed my glass. Then I made my own pcb with all the parts they suggest. On the next rev I'll add an sd card. Schematic attached.

Thanks,

Very cool. Thanks for sharing the schematic.
