-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
-------
-
-
-Work in progress...
-
-
-OLED Configuration
--------------------------------
