It’s the 20th anniversary of the Retro Challenge<\/a>, and also the 10th anniversary of the RC2014<\/a> Z80 computer.

So to celebrate, I’m planning on taking part this year, and undertaking a project with my own RC2014 computer. The idea is to complete a project using a retro computer in a month. The RC2014 itself was an entry in 2014.

As I will only have a month to try to complete a project, I’m looking for something achievable.

My plan at the moment is to look at adding rotary encoders to my RC2014, and to be able to read them using Z80 machine code. A rotary encoder is\u00a0a sensor that measures the rotational position and speed of an object by converting the motion into an electrical signal. An example would be the scroll wheel on a computer mouse.

I have ordered a couple of rotary encoders ahead of the start date so they should be here in time for the start of the project. I have used a rotary encoder on an Arduino a few years ago, but that had a library to simplify the process. This time I will have to write from scratch, and it will give me a good opportunity to write some real Z80 assembly.

I will also need to design a circuit board, and for this I plan to use EasyEDA. This is an area I really need to learn more about, so the challenge gives me a good excuse to get stuck in with it. I will need to start on this early as ordering a PCB can take a few weeks to arrive, so I won’t have time for multiple revisions if I make a mistake.

Let’s see if I can produce something by the end of the project!<\/p>\n","protected":false},"excerpt":{"rendered":"
