Arduino/ESP8266 SSD1322 Library

For Newhaven NHD-3.12-25664UCY2 OLED Display

The Adafruit GFX introduces graphics primitives (points, lines, circles, etc.). This library add support for the Newhaven NHD-3.12-25664UCY2 256x64x16 Yellow OLED Display. The driver supports 4-wire SPI mode.

!! Do not use a version of the Adadfruit GFX library newer then v1.5.3 !!

This repository was forked from ESP8266_SSD1322 that in turn was based on Adafruit SSD1306.

Introducing support for Arduino 101

Changes compared to ESP8266_SSD1322:

• Add support for the Arduino 101 (native 3.3 Volt, base on Intel Curie)
• Along the way, I did some minor touch ups:
  • add support for !RESET connected to hardware reset instead of GPIO pin (saves me 1 pin)
  • remove unused variables (rowTerminated, offScreen, color)
  • suppress compiler warning strict-aliasing when accessing fonts
  • remove unused pointer value access e.g. string++ instead of string++
  • add test for flash_address unassigned
  • add headers to files indicating support for SSD1322.

Wiring

OLED	Arduino 101
#1 (Vss)	GND
#2 (Vdd)	3V3 (up to 271 mA, use external power supply to Arduino 101)
#4 (D/!C)	D9
#7 (SCLK)	D13 (hardware SPI SCLK)
#8 (SDIN)	D11 (hardware SPI MOSI)
#16 (!RESET)	!RESET
#17 (!CS)	D10
#5,#6,#10-14,#19,#20	GND
#3, #9, #15, #18	not connected

Tested and passed on Arduino 101. I like this display, and being able to use the Adafruit GFX primitives is even better!
