# SSD1306xLED demo

Runs through the basic features of [ssd1306xled](https://github.com/tejashwikalptaru/ssd1306xled) on an ATtiny85 with a 128x64 I2C OLED.

## What it does
- Fades the screen through a few fill patterns
- Prints text using the built-in 6x8 font
- Draws two full-screen bitmaps from PROGMEM arrays

The whole thing loops, so you can watch it cycle without touching anything.

## Wiring

  | OLED | ATtiny85 |
  |------|----------|
  | VCC  | VCC (pin 8) |
  | GND  | GND (pin 4) |
  | SCL  | PB2 (pin 7) |
  | SDA  | PB0 (pin 5) |
  
Default I2C address is 0x3C. If your module uses 0x3D, define `SSD1306_SA` before including the header.

## Library
