image2oled

image2oled is a simple tool to change images into byte arrays (or your array back into an image) for use with Arduino and (monochrome) displays such as OLEDs. It was originally made to work with the Adafruit OLED library. An example sketch for Arduino and this library can be found here.

More info (and credits) can be found in the Github repository. This is also where you can report any issues you might come across.

This version, image2oled, simplifies the process for the 128x64 OLED for uploading to the arduino and storing the bitmap in a seperate header file.
