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.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
