This project, consisting mainly of a graphic library and a simple hardware project based on the ESP32 SOC, implements a VGA output that can be connected to any monitor and two PS / 2 inputs to connect mouse and keyboard.
The FabGL library makes it easy to:
- draw graphic primitives (lines, circles, images, etc.) to be displayed on the VGA monitor
- check and accept input from a PS / 2 mouse
- check and accept input from a PS / 2 keyboard
- emulate an ANSI / VT terminal (with 80x25 or 132x25 characters and with different fonts)
- the VGA output allows different resolutions and up to 64 colors
- double buffering at low resolutions
- unlimited number of sprites (with collision detection)
- user interface with windows (windows, buttons, edit box, combobox, etc ...)

The library is written in C ++ is Open Source, and is already present in the Arduino IDE libraries
