An Arduino v1.0+ library for Newhaven OLED displays, such as the NHD‐0420DZW series.
This is an edit to Elco Jacobs OLED library (here), which would not compile under v1.0+ of the Arduino IDE (Tested on v1.0.5).
This library is for the 4-bit parallel interface. See the datasheet for wiring diagrams.
To use, just copy the OLEDFourBit folder into arduino-1.x.x/libraries. Initialization and available functions are identical to the default Arduino LiquisCrystal library. An example sketch is included.
