An ESP32-based VGA computer with BASIC, graphics & sound #ESP32
Stefan Lenz has built a home computer with VGA, sound and optional network support based on an ESP32 microcontroller. The Lilygo TTGO VGA ESP32 development board is key, combining an ESP32 microcontroller with VGA and PS2 connectors in a compact unit.
This tutorial is about building a 80s style home computer with BASIC interpreter on the basis of FabGL and the ESP32 microcontroller family. The system supports sound, graphics, and networking. Input device is a PS2 keyboard.
The microcontroller hardware is a board produced by TTGO with the VGA, PS2, and audio sockets already installed. It was originally designed for retro computing and running emulators of 70s and 80s operating systems. The project here showcases a BASIC interpreter that has been newly developed.
