This is a library for GP1287AI/BI VFD displays. These displays use SPI to communicate, 3 to 4 pins are required to interface. These displays have 256x50 pixel area and require significant RAM size to store screen buffer, will not work on ATmega328/32u4 boards. Written by Vitaly Baranov based on Adafruit SSD1306 library.

Preferred installation method is to use the Arduino IDE Library Manager. To download the source from Github instead, click "Clone or download" above, then "Download ZIP." After uncompressing, rename the resulting folder Adafruit_SSD1306. Check that the Adafruit_SSD1306 folder contains Adafruit_SSD1306.cpp and Adafruit_SSD1306.h.
You will also have to install the Adafruit GFX library which provides graphics primitves such as lines, circles, text, etc. This also can be found in the Arduino Library Manager, or you can get the source from https://github.com/adafruit/Adafruit-GFX-Library
