## Library
C library is aimed for driving [SSD1306 0.96" OLED display](#demonstration) 128x64 through TWI's Atmega328p.
C library is aimed for driving [0.96" OLED display with SSD1306 driver](#demonstration) 128x64 through TWI's Atmega328p.
### Versions
- 1.0 - basic functions.
- 2.0 - change whole logic -> rebuild to cacheMemLcd array. It means that every request is stored in cache array and then is depicted on the display by function [SSD1306_UpdateScreen (uint8_t)](#ssd1306_updatescreen). Added new function -> [SSD1306_DrawLine (uint8_t, uint8_t, uint8_t, uint8_t)](#ssd1306_drawline).
- 1.0 - basic functions. The first publication.
- 2.0 - more changes:
- rebuild to cacheMemLcd array. It means that every request is stored in cache array and then is depicted on the display by function [SSD1306_UpdateScreen (uint8_t)](#ssd1306_updatescreen).
- Added new function -> [SSD1306_DrawLine (uint8_t, uint8_t, uint8_t, uint8_t)](#ssd1306_drawline). Possible depicted any line (horizontal, vertical, with slope).
- Possible to use for more than 1 display (not tested, cause displays that I have avialable had the same addresses).
