If you're going to do I2C just get an LCD display. This OLED can be driven at 150fps by simple devices like an ardunio which is where it really shines - super crisp, high contrast, smoove as buttah graphics for realtime readouts etc. OLED over SPI is really visually impressive stuff and effectively 0 latency. Using the SSD1306 for static displays over I2C is almost a crime.
