OLED Confusion
« on: January 14, 2011, 09:03:46 PM »
Hey guys, quick question about and article I saw of HaD. The article has a video that shows and arduino controlling a color lcd display, and I was wondering how what handles all the graphics processing. Surely not the arduino.

Heres the article:

And video:

SPI has a bad rap of being slow when it comes to displays. With a bit of fiddling it is possible to get 500k pixels per second from a Arduino Duemilanove which is more than enough perf for these small screens: >30fps on 128x128.

Apparently it is. Best check out the source code.

Apparently they come in touch screen:

uOLED-32028-P1T running MIDIZAMP

From what I can understand there's a graphics processing chip on the screen. Found these for those that are interested:
