MicroPython_PCD8544

This project provides a MicroPython driver for controlling Nokia 5110 PCD8544 LCD displays on ESP8266 microcontrollers. It enables developers to display text and graphics on these low-cost, low-power displays commonly used in embedded projects and IoT devices.

Key Features

• Text Display — Print characters and strings with automatic cursor advancement and screen wrapping.
• Graphics Support — Draw pixels, lines, rectangles, triangles, and circles (filled or outlined) via an included graphics library.
• Memory-Efficient Font Handling — Uses a compact 5x7 font file loaded on-demand to conserve RAM.
• Buffer Management — Separate display buffer operations (clear, update) for efficient screen control.
• Pin Configuration — Flexible pin assignment for hardware compatibility.

Philosophy

The driver prioritizes minimal memory usage and straightforward integration, making it suitable for resource-constrained MicroPython environments on ESP8266.
