Detailed Description

Driver for SSD1306, SSD1315, and SSH1106 OLED displays.

Bit-bangs I2C via the ATtiny85 USI peripheral. No Wire library needed – saves about 1 KB of flash compared to TinyWireM. Works on any AVR with USI by redefining the pin macros.

Originally by Neven Boyanov (Tinusaur). I2C rewrite based on TinyI2C by David Johnson-Davies. Maintained by Tejashwi Kalp Taru.

Version: 1.0.0
