/AY-3-3910-Player

This project is to make real hardware AY-3-3910 player using the real part and is Arduino based, and should use the minimum of hardware component.

Primary LanguageC

  0. You just DO WHAT THE FUCK YOU WANT TO.
  1. If you like this software you can send me a (virtual) postals
     card. Details bellow:

Now the formal things are done.

This small project is to provide a simple and easy way to play YM
files on a computer using the less possible component.

It is currently only using a resistor, a AY-3-3910 (but any version
is fine for playing music), a femal audio jack connector to let you
ear the nice sound, an Arduino, a buch of wire, and nothing more.

Most project I saw before was using a quartz to provide a clock to
the AY, but this is just useless and expensive when you have a µC
with timers :)

As the Arduino does not have enought memory to store the YM file,
it is stream from the PC trought the USB virtual serial port.

You can find a Fritzing schematic in the file 
project-ay-3-3910-breadboard.png

This project may evolve in a fully autonomous Arduino capable of
playing YM/MYM file without the need of a PC. I may use the
Gameduino2 for its display and SD connector.

*********************************************************************

I've included a simple MYM file with this project: Thrust.mym
It's the Title music of the game Thrust on the Atari ST, music
composed by Rob Hubbard.

To convert ym to mym I recommend the ym2mym tool that come with the
OSDK (Oric SDK) that can be found here: http://osdk.defence-force.org

Enjoy!
