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 with Multiple Displays – Part 3

Whilst messing around a little more with my Arduino with Multiple Displays – Part 2, I've optimised the code a little and found out a bit more about these displays! In this part, I'm actually using a PCB that can hold four displays, powered by a Waveshare Zero device. More on that here: Waveshare Zero Multi … Continue reading Arduino with Multiple Displays – 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 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 MIDI Atari Paddles

Finally, I get to the point where I can do something vaguely musical with my Atari 2600 Controller Shield PCB. This turns it into a simple MIDI CC controller using the Atari paddles. https://makertube.net/w/dgK7y73KfC1SWc5z2wsJ6x Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not responsible for any damage to … Continue reading Arduino MIDI Atari Paddles →

Atari 2600 Controller Shield PCB Revisited

As previously mentioned in my Atari 2600 Controller Shield PCB Build Guide the PCB doesn't work so well with paddle controllers due to the way they are wired up. This is an update to the PCB to allow the paddles to be used in a very similar way to the original Atari 2600. Warning! I strongly … Continue reading Atari 2600 Controller Shield PCB Revisited →

Atari 2600 Controller Shield PCB Build Guide

Here are the build notes for my Atari 2600 Controller Shield PCB Design. Recall from my design notes that this version doesn't deal with paddles very well Here is an updated version that supports paddles better, but at the expense of requiring more complex code to read them: Atari 2600 Controller Shield PCB Revisited. Warning! I strongly … Continue reading Atari 2600 Controller Shield PCB Build Guide →
