Garvuino

The Garvuino is a PCB board for creating music, sounds and chiptunes, either through programming, soundtracker or live recording (midi).

It works with an Arduino Nano and an Atmega8 chip.

Manual

You can find the full manual here.

Features

  • AY-3-8910 emulator (using an atmega8 chip): it can replay Sinclair ZX Spectrum, Atari ST, Amstrad square wave chiptunes from the sd card.
  • Sid emulator: play some C64 musics, or use it as a midi synth with a fat sound.
  • 1-bit music: play beeper music.
  • Mozzi synth: fun FM sounds and many other effects, driven by MIDI or some captors.

SID emulator

Beeper

Atmega8 setup

Please refer to the manual and this folder for more info about setting up the atmega8 chip.

PCB

Please refer to this folder for the fritzing sources and gerber files.

Breadboard

It can also work without the PCB. Just use a breadboard and a few wires!

Please refer to this folder for the fritzing sources and pdf version.

Arduino sketches

You can find some tunes for using with the AVR-AY setup in here. The arduino sketch can read the RSF files from the SD (it can't read the YM or AY files directly). You can convert to RSF with the AVR-AY Player.
