Arduino AY-3-8910 Shield Design

Having build my AY-3-8910 Experimenter PCB I thought a slightly simpler format board would be useful, so I've put together an Uno shield-format PCB that can support one or two AY-3-8910 chips.

Arduino and AY-3-8910 – Part 5

My next bit of messing around with Arduno and AY-3-8910 takes my AY-3-8910 Experimenter PCB Design and adds some simple MIDI reception to create a 12-channel AY-3-8910 tone module. Part 1 - Getting started and looking at playing YM files. Part 2 - Adding basic MIDI control. Part 3 - Basic experiments with direct digital synthesis. Part 4 - … Continue reading Arduino and AY-3-8910 – Part 5 →

Z80 and AY-3-8910

Finally starting to look at the Arduino and AY-3-8910 was triggered by a couple of things recently. First getting an RC2014 and playing with AY-3-8910 based sound on that. But also, having visiting RetroFest in Swindon this year, talking to Dean Belfield about the methods he used to develop for the ZX Spectrum and how … Continue reading Z80 and AY-3-8910 →

Arduino and AY-3-8910 – Part 4

After Part 3 I started to go back and add MIDI, and changed the waveform on the touch of a button, and then started to wonder if I could add envelopes and so on. And then it occurred to me, I didn't really need to re-implement my own synthesis library, I could probably write a custom … Continue reading Arduino and AY-3-8910 – Part 4 →

Arduino and AY-3-8910 – Part 3

I suggested in Part 2 that it might be possible to do some simple modulation of the amplitude of the AY-3-8910 channels rather than drive frequencies directly. This is taking a look at the possibilities of some kind of lo-fi direct digital synthesis using that as a basis. Part 1 - Getting started and looking at … Continue reading Arduino and AY-3-8910 – Part 3 →

Arduino and AY-3-8910 – Part 2

Following on from my initial experiments in Arduino and AY-3-8910 this post looks at the sound generation capabilities in a little more detail and adds some basic MIDI control. Part 1 - Getting started and looking at playing YM files. Part 2 - Adding basic MIDI control. Part 3 - Basic experiments with direct digital synthesis. Part 4 … Continue reading Arduino and AY-3-8910 – Part 2 →

Arduino and AY-3-8910

I've had some AY-3-8910 programmable sound generators for a while and planned to do something with them, but they've sat in the "to think about" box for a while. But recently getting hold of the WhyEm sound card for the RC2014 has re-awakened my interest. This is some "first looks" experiments with the AY-3-8910 and … Continue reading Arduino and AY-3-8910 →
