Almost 3 years ago I developed and published ZEPPP, my Arduino-based, “Zero-External-Parts” PIC Programmer, and wrote about it here on my blog. From time to time I hear from people using it, and, sometimes I would also get questions about whether specific PIC devices are supported. Now, ZEPPP is pretty limited in scope, as it […]
So in my first adventure with the STONE displays I wrote a simple Arduino library to communicate with them, and ported the firmware-side of the included example to my library to make sure it was working properly. However, writing that library was not the end goal. I wrote it to make it to get familiar […]
HMI?! HMI stands for Human Machine Interface, which is a fancy way of describing an element that enables the interaction between a human and a machine. In this case, we will be talking about HMI displays. In particular HMI displays manufactured by a company called STONE. What makes their screens different to regular touchscreens? Well, […]
One of the things I’ve been interested in for the last year or so, is developing for the Atari family of 8-bit computers. I haven’t done a lot yet, but I’ve been slowly getting software, docs, and hardware to start writing code with all the tools I could possibly need. I had already built a […]
A couple of months ago I was asked if I could prepare a sort of workshop on one of my favorite topics: ASM Programming for PIC microcontrollers, which I of course accepted on the spot. Now, I wanted to include a couple of “hands-on” lab sessions in this workshop, and because of this, I needed […]
As a break from my regular activities I decided to spend a week designing and building something with parts and components I’ve purchased over the years but never had the chance to use in a project. This is the result: A sort of portable gaming device powered by a really old AVR microprocessor. I’ll try […]
