SP0256A-AL2 Sings the Twelve Days of Christmas

Partly prompted by a programming challenge by Futzle on Mastodon, I thought it might be interesting to try to get my Arduino and SP0256A-AL2 to sing the Twelve Days of Christmas. https://makertube.net/w/diBkzrhkh3tekAPBhGzrVj Warning!

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 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 SP0256A-AL2 – Part 2

After getting the Arduino and SP0256A-AL2 working I wondered if I could repeat the trick from the Arduino and AY-3-8910 and have the Arduino generate the required clock signal for the SP0256A-AL2. This post starts to look at that question. Part 1 - Basic introduction and getting started Part 2 - Arduino programmable clock Part 3 - … Continue reading Arduino and SP0256A-AL2 – Part 2 →

Arduino and SP0256A-AL2

Having had a bit of a play with the SP0256A-AL2 Speech Synthesis chip, this post looks at how to drive it directly from an Arduino. 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 … Continue reading Arduino and SP0256A-AL2 →

SP0256A-AL2 Speech Synthesis

I had one of those moments recently when reading an article online sent me into a bit of a major tangent. The article in question was talking about the SP0256-AL2 speech synthesizer chip. And if you heard a computer talking in the 1980s, then chances are it was probably this chip doing all the hard … Continue reading SP0256A-AL2 Speech Synthesis →
