## What it is
Arduino_GFX is an Arduino graphics library supporting various color displays (LCD, OLED) over multiple data bus interfaces such as SPI, parallel, and RGB. It is a rewrite inspired by Adafruit_GFX, LovyanGFX, TFT_eSPI, and Ucglib, with simple declaration APIs and U8g2/UTF8 font support.

## Use cases
- drive a tft lcd from esp32 with arduino
- draw text and graphics on an oled display
- render utf8 unicode text on arduino display
- support multiple display bus interfaces like spi and parallel
- get started quickly with supported dev devices like lilygo t-deck
- port adafruit_gfx style code to more displays

## When to choose
- you need broad display and data bus support in one arduino library
- you want simple, Adafruit_GFX-like APIs with modern display support
- you need UTF8/U8g2 font rendering on small MCUs

## When to avoid
- you are not on an Arduino-compatible embedded platform
- you need GPU-accelerated or high-level UI framework features beyond basic graphics
- your display is unsupported and you cannot write a custom driver

## Facets
- artifact type: library
- maturity: active
- function: graphics, ui-components, embedded
- domain: embedded-systems, hardware, graphics
- platform: embedded, iot, cpp
- tags: arduino, tft, lcd, oled, spi, esp32, display-driver, gfx-library
