SSD1306

Readme
 
This is a C language project that demonstrates the Inter-Integrated Circuit interface (I2C). This project interfaces the SSD1306 OLED display. The OLED is available on Amazon.com, see https://www.amazon.com/s?k=SSD1306.

 
The following figure shows the interface to the MSPM0.

The next figure shows the orientation of the pixels on the display.

The last figure shows the orientation of the strings on the display.


 
Derived from Texas Instrument code
