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
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.
