A derived version of the BSD licensed Adafrut GFX library for the SSD1306 controller for an OLED 128x32 or 128x64 display using SPI or I2C.

Last commit 11 Nov 2014 by Neal Horman

This is an SPI or I2C driver, font, and graphics drawing library as initially provided by Adafruit which has been modified for use in the mbed envionment.
