FabGL makes an ESP32 an entire usable computer #ESP32 #Emulation #VintageComputing

FabGL is mainly a Graphics Library for ESP32. It implements several display drivers (for direct VGA output and for I2C and SPI LCD drivers). FabGL can also get input from a PS/2 Keyboard and a Mouse. ULP core handles PS/2 ports communications, leaving main CPU cores free to perform other tasks.

FabGL also implements an Audio Engine, a Graphical User Interface (GUI), a Game Engine and an ANSI/VT Terminal.

This library works with ESP32 revision 1 and up. See a list of prefab boards.

VGA output requires a digital to analog converter (DAC): it can be done by three 270 Ohm resistors to have 8 colors, or by 6 resistors to have 64 colors.

There are a number of emulators written to use FabGL including one for an IBM PC, CP/M, Altair 8080 and more.
