High Performance Decoupled Buses for IoT Displays

Herein, I present a method of achieving high performance bus I/O for IoT display drivers such that the display driver code is independent of the bus it operates on, whether it's I2C, SPI, 8-bit parallel, or some future variant. This way, you can write one SSD1306 driver to handle both the I2C and SPI variants of that display. Similarly, you can create one ILI9341 driver and run it in SPI or parallel.
