# SSD1306 0.96" OLED display

## SSD1306 Description
Detailed information are described in [Datasheet SSD1306](https://cdn-shop.adafruit.com/datasheets/SSD1306.pdf).

## Library
C library is aimed for driving [SSD1306 0.96" OLED display](#demonstration) 128x64 through TWI's Atmega16.

### Usage
Prior defined for MCU Atmega16. Need to be carefull with TWI ports definition.

| SDA | PC1 | PC4 |

### Tested
Library was tested and proved on a **_SSD1306 0.96″ OLED Dispay_** with **_Atmega16_**.

## Init OLED Sequence
Init sequence OLED display was defined according to page 64 (next to last page) of [Datasheet SSD1306](https://cdn-shop.adafruit.com/datasheets/SSD1306.pdf).
