This is an example for our Monochrome OLEDs based on SSD1306 drivers
|
|
|
|
Pick one up today in the adafruit shop!
|
|
------> http://www.adafruit.com/category/63_98
|
|
|
|
This example is for a 128x32 pixel display using I2C to communicate
|
|
3 pins are required to interface (two I2C and one reset).
