The original schematics I provided for the Arduino + AY-3-8910 was a bit crude for the audio output, it works, but it’s easy to get the audio saturate. I will propose you an update on this, taken from an actual schematic, the one used on the Oric 1/Atmos Continue reading Update on AY-3-8910 schematic

Another AY entry :)
Hello everyone 🙂
After my previous post on Arduino an AY-3-3910 / YM2149 a lots of people complain that I didn’t deliver the code for the playing with a YM/AY chip with an Arduino, WITHOUT using any external hardware especially not a quartz 🙂
I know that lots of people complain the first time that I didn’t deliver the code for the playing with a YM/AY chip with an Arduino, WITHOUT using any external hardware especially not a quartz 🙂
I told at the time that I won’t deliver until I made a YM player.
Well I didn’t do a YM player. Sorry to tell that.
Playing with Arduino and YM2149
Today, I played with my Arduino to connect a Yamaha YM2149 ( know too as AY-3-8910. After some times I finally got it to work !
And contrary to all other works I saw, I didn’t use an external Quartz, the 2Mhz clock I used is generated by the AVR chip.
