|
* 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!
