This is a library for our Monochrome OLEDs based on SSD1306 drivers

|
|
|
These displays use SPI to communicate, 4 or 5 pins are required to
|
|
interface

I change the adafruit SSD1306 to SH1106
|
|
|
|
SH1106 driver similar to SSD1306 so, just change the display() method.
|
|
|
|
However, SH1106 driver don't provide several functions such as scroll commands.
