Arduino and SP0256A-AL2 – Part 6

Finally I'm doing something arguably slightly musical with my SP0256A-AL2! Playing it over MIDI. Part 1 - Basic introduction and getting started Part 2 - Arduino programmable clock Part 3 - Using a Raspberry Pi Pico as a programmable clock Part 4 - Using a HC4046 PLL as the clock Part 5 - Using an I2C SI5351 programmable clock … Continue reading Arduino and SP0256A-AL2 – Part 6 →

Arduino SP0256A-AL2 Shield PCB Build Guide

Arduino SP0256A-AL2 Shield Design

Having spent quite a bit of time with an Arduino hooked up to an SP0256A-AL2 on a solderless breadboard, and now that I've got some ideas for how I want to sort out the clock, I thought it time to create a PCB to save the unreliable wiring getting in the way! Arduino SP0256A-AL2 Shield … Continue reading Arduino SP0256A-AL2 Shield Design →

Arduino and SP0256A-AL2 – Part 5

This looks at another of the options from Part 4 - the I2C programmable Si5351 clock source. Part 1 - Basic introduction and getting started Part 2 - Arduino programmable clock Part 3 - Using a Raspberry Pi Pico as a programmable clock Part 4 - Using a HC4046 PLL as the clock Part 5 - Using an I2C SI5351 … Continue reading Arduino and SP0256A-AL2 – Part 5 →

Arduino and SP0256A-AL2 – Part 4

Having now tried both an Arduino and Raspberry Pi Pico as programmable clocks for the SP0256A-AL2, this post starts to look at some alternative solutions, starting with a HC4046 phase-locked loop, voltage-controlled oscillator clock. Part 1 - Basic introduction and getting started Part 2 - Arduino programmable clock Part 3 - Using a Raspberry Pi Pico as … Continue reading Arduino and SP0256A-AL2 – Part 4 →

Arduino and SP0256A-AL2 – Part 3

Following on from using an Arduino as a variable clock in Arduino and SP0256A-AL2 – Part 2, I have some ideas for a few options, but this post looks in detail at using a Raspberry Pi Pico as the clock source. Spoilers: it kind of works, but isn't quite the answer I need yet... Part 1 … Continue reading Arduino and SP0256A-AL2 – Part 3 →

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 →

AY-3-8910 Experimenter PCB Design

Following on from my Arduino and AY-3-8910 experiments, one thing I wanted to do was to try to hook up several AY-3-8910 devices and see if I could stack up the polyphony a little. But that is a lot easier without jumper wires, hence this PCB to support some more experiments with an Arduino Nano. … Continue reading AY-3-8910 Experimenter PCB Design →
