## What it is
FabGL is a C++ graphics and input library for the ESP32, providing display drivers for VGA, PAL/NTSC composite video, and I2C/SPI LCDs, plus PS/2 keyboard and mouse support. It also bundles an audio engine, a widget-based GUI, a game/emulation engine, and an ANSI/VT terminal emulator.

## Use cases
- render graphics on a VGA monitor from an ESP32
- build retro games or emulators on ESP32
- connect a PS/2 keyboard and mouse to ESP32 projects
- create a GUI with windows and widgets on small displays
- implement a VT100/ANSI terminal on ESP32 hardware
- generate multi-channel sound with DAC or sigma-delta output
- drive SSD1306, ST7789, or ILI9341 displays from ESP32

## When to choose
- you are building display, input, sound, or retro-computing projects on ESP32
- you need VGA or composite video output with sprites and double buffering
- you want an all-in-one library with GUI, terminal, audio, and game engine support

## When to avoid
- you are not targeting the ESP32 platform
- you need the latest ESP-IDF versions, which leave insufficient free memory for FabGL
- you require a permissive commercial-friendly license without contacting the author (GPL v3)
