* @file Adafruit_GrayOLED.h |
|
* |
|
* This is part of for Adafruit's GFX library, supplying generic support |
|
* for grayscale OLED displays: http://www.adafruit.com/category/63_98 |
|
* |
|
* These displays use I2C or SPI to communicate. I2C requires 2 pins |
|
* (SCL+SDA) and optionally a RESET pin. SPI requires 4 pins (MOSI, SCK, |
|
* select, data/command) and optionally a reset pin. Hardware SPI or |
|
* 'bitbang' software SPI are both supported. |
|
* |
|
* Adafruit invests time and resources providing this open source code, |
|
* please support Adafruit and open-source hardware by purchasing |
|
* products from Adafruit! |
