Character only library for OLED display

[fat16lib]

I wrote a character only library for the Monochrome 128x32 OLED graphic display. It should also work on the 128x64 display but I have not tested it since I don't have this display.

This library is not buffered so it uses about 500 bytes less RAM than the Adafruit graphic library.

This neat tiny display can used in place of a standard LCD in projects that are short of RAM by using this library.

The file is SSD1306ASCII20120229.zip at http://code.google.com/p/beta-lib/downloads/list.

Here is the readme file:

SSD1306ASCII is an unbuffered character only library for an Adafruit 1306
OLED display. The SSD1306ASCII library only requires a few bytes of RAM.

SSD1306ASCII implements a small part of the LiquidCrystal API. Implemented
functions include clear(), home(), print(), setCursor(), and write().

It has only been tested with the "Monochrome 128x32 OLED graphic display".

To use this library, copy the SSD1306ASCII folder to your libraries folder.

Edit SSD1306ASCII.h and select your display type. The default is:

// #define SSD1306_128_64
#define SSD1306_128_32

Select the font that will be used by defining FONT_TYPE. The default is:

#define FONT_TYPE 1

This is an 96 character version of the Adafruit glcdfont.

See SSD1306fonts.pdf for a rough representation of other choices.

Try the ssd1306HelloWorld example first.

The ssd1306ShowFont example displays all characters in the font.

The ssd1306FontMap example was used to generate SSD1306fonts.pdf.

Thank you! Since my little project doesn't require graphics, only text I easily replaced the Adafruit library with this one and not only did it give me a little more RAM, it reduced the program code itself about 2k as well.
This is great for those that don't require fancy graphic capabilities and only use text.

... It should also work on the 128x64 display but I have not tested it since I don't have this display ...

I did some quick testing with my 128x64 display. Both HelloWorld and ShowFont examples work with the bigger display.

Fantastic. Much easier to use than the sample librarary. Thank you for sharing it with us.
Question: is there a character for Omega? Ω
