SSD1306 OLED Display via I2C
|
||||
======
|
||||
|
||||
Features
|
||||
--------
|
||||
|
||||
Some features supported by the firmware:
|
||||
|
||||
|
||||
* I2C connection between the two halves is required as the OLED display will use this connection as well. Note this
|
||||
requires pull-up resistors on the data and clock lines.
|
||||
* OLED display will connect from either side
|
||||
|
||||
|
||||
Wiring
|
||||
------
|
||||
|

|
||||

|
