A simple and lightweight C++ project for writing text to an SSD1306 OLED screen using Raspberry Pi Zero 2 W. The project is designed for headless SSH development and directly communicates with the OLED screen over I2C.

• Text rendering on 128x64 SSD1306 OLED display
• Framebuffer-based character drawing using custom 5x7 font
• Basic graphics primitives (horizontal lines, pixel control)
• Built with g++ and standard Makefile
• SSH-based deployment and execution (no GUI required)

• Raspberry Pi Zero 2 W (or any Pi with I2C)
• SSD1306 OLED screen (128x64, I2C interface)
• C++17 compiler (e.g., g++)
• Wiring:

| OLED Pin | Raspberry Pi Pin |
