micropython-oled

MicroPython OLED is a collection of drivers for monochrome OLED displays, designed specifically for MicroPython environments. It provides a lightweight, performance-focused alternative to existing drivers, prioritizing memory conservation and speed for resource-constrained embedded systems.

Key Features

• Memory Efficiency — Each driver is a self-contained file using only the built-in framebuf module, avoiding inheritance and multiple imports to minimize memory usage.
• Performance Optimized — Calls MicroPython built-in functions directly and reuses pre-allocated buffers to maximize speed.
• Display Control — Includes convenience functions for flipping, mirroring, reversing colors, hardware scrolling, contrast adjustment, and power switching.
• Frame Buffer Access — Drawing functions are available via the fb attribute on the frame buffer object, following MicroPython's standard patterns.
• Multiple Protocols — Supports both I2C and SPI interfaces for compatible displays like SH1106.

Philosophy

The project prioritizes minimal memory footprint and raw performance over convenience abstractions, accepting code repetition between drivers as a trade-off for efficiency in constrained embedded environments.
