Hideki Kozima / OLEDaccel

This library provides an OLED (SSD1332, 96x64xRGB) interface that best utilizes SSD1332's graphic accelerator (especially for drawing lines and rectangles). Though it still has some limitations --- it does not support 'clipping', odd numbers for circle/ellipse diameter, and so on, it runs quite fast. Enjoy the speed.
