## What it is
A fast display graphics library for ESP32, ESP8266, and ATSAMD51 supporting SPI, I2C, and parallel-connected LCD/OLED/EPD panels. It offers AdafruitGFX/TFT_eSPI-compatible APIs with DMA transfers, sprite rotation/scaling, multi-display support, and composite video output on ESP32.

## Use cases
- draw graphics on a TFT LCD with ESP32
- render sprites with fast rotation and scaling on microcontrollers
- drive multiple displays simultaneously from an ESP32
- output NTSC or PAL composite video from ESP32
- port a TFT_eSPI or AdafruitGFX project to a faster library
- display UI on M5Stack or Wio Terminal devices
- use DMA transfers to draw while running other code

## When to choose
- building Arduino or ESP-IDF projects with ESP32/ESP8266/SAMD51 displays
- you need high-performance drawing with DMA and sprite support
- targeting M5Stack, TTGO, ODROID-GO, or Wio Terminal hardware
- you want AdafruitGFX/TFT_eSPI API compatibility with better speed

## When to avoid
- targeting non-ESP32/SAMD51 microcontrollers like AVR or STM32
- developing desktop or mobile graphics applications
- you need a full GUI framework with widgets rather than a drawing library

## Facets
