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.
This repository was forked from ESP8266_SSD1322 that in turn was based on Adafruit SSD1306.
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 ofstring++ - add test for
flash_addressunassigned - add headers to files indicating support for SSD1322.
| 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!
