Detailed Description

SSD1306 OLED driver implementation.

I2C is bit-banged through the ATtiny85 USI peripheral rather than using the Wire library. This saves about 1 KB of flash. The implementation is based on TinyI2C by David Johnson-Davies.

Display data goes straight to the SSD1306 over I2C – there is no local framebuffer. This keeps RAM usage near zero but means every draw call is an I2C transaction, and the display cannot be read back (no read-modify-write).
