## What it is
The official Arduino library for M5Stack Core (Basic/Gray) ESP32 development kits, providing access to the LCD, buttons, speaker, power management, and IMU via a unified M5 class. It is now deprecated in favor of the M5GFX and M5Unified libraries.

## Use cases
- draw graphics and render images on an M5Stack LCD from Arduino
- read button presses on an M5Stack Core device
- play tones through the M5Stack speaker
- read battery level and control power on M5Stack
- read accelerometer data from M5Stack Basic or Gray
- program ESP32-based M5Stack hardware with Arduino

## When to choose
- maintaining legacy Arduino sketches written for the original M5Stack library
- targeting older M5Stack Basic or Gray hardware with existing example code

## When to avoid
- starting a new M5Stack project - use M5Unified and M5GFX instead
- working with newer M5Stack devices like M5Stick or Core2
- needing ongoing support or new features

## Facets
- artifact type: library
- maturity: maintenance
- function: graphics, audio-processing, sdk
- domain: embedded-systems, iot, hardware, developer-tools
- platform: embedded, cpp, c
- tags: arduino, esp32, m5stack, deprecated, display-driver, hardware-library
