This is how I wired the Arduino up with the shift registers and the EEPROM chip. It looks very confusing but most of that is just the data and address buses, which follow a very logical pin mapping. I ...

These two sketches read/write type 2532 4k and 2516 2k UV-erasable EPROMs. It was developed to troubleshoot/replace ROMs in an old arcade machine.

Every time one of us flashes an Arduino’s internal memory, a nagging thought in the backs of our minds reminds us that, although everything in life is impermanent, nonvolatile re-writable memory is ...

Last week I spent most of my leisure time studying nonvolatile memory chips. The result was a better understanding of Arduino’s EEPROM. This might look like novice work, but I hope my thoughts will ...

Joe is a graduate in Computer Science from the University of Lincoln, UK. He's a professional software developer, and when he's not flying drones or writing music, he can often be found taking photos ...

Most video game manufacturers aren’t too keen on homebrew games, or people trying to get more utility out of a video game system than it was designed to have. While some effort is made to keep people ...

This is a useful addition to my previous article “Arduino EEPROM”. The article is still available. I have provided a link here for convenience https://www.edn.com ...

In this video I'm showing you the basics of using the Arduino EEPROM and showing you a trick that you can utilize to have a default set of values saved in the Arduino EEPROM on the first run of your ...
