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 […]
It took me a really long time to do this second part of my Pi-based Logic Analyzer project, mostly because of two things; the first one being that at one point (after I had pretty much all the case design, extra hardware and software tweaking done for my RPi1) I decided to switch to a Raspberry Pi […]
I got the chance to play with an Intel Edison board a couple of months ago, and I just got my own board today, so I spent a bit of my afternoon settings things up, and playing with it. One thing I noticed, is that most tutorials and guides for the Edison were written for the version of the […]
If you are using your Arduino’s PRNG (Pseudo-Random Number Generator) for anything more serious than flashing random lights for your Christmas decorations, there’s a chance you might run into some unexpected issues, as the random() function in Arduino seems to be somewhat broken. Why? Let me explain. Background Most basic random number generators in programming libraries and platforms are based on what is called […]
For a few months now (and after successfully using a cheap USB analyzer with my Pocket C.H.I.P) I’ve wanted to make a sort of standalone Logic Analyzer / mini linux machine that I could have on my bench. I originally wanted to use one of my C.H.I.P boards, but I soon stumbled upon a bit of a difficulty: It’s […]
A recent discussion on the Pocket C.H.I.P forums made me dig up memories of my time with DJGPP (a wonderful DOS port of GCC), and its quite functional text-based IDE; RHIDE. I thought that it would be great to have RHIDE running on my Pocket CHIP for doing simple C/C++ development on the go, as […]
So a time ago I purchased a cheap USB Logic Analyzer from eBay that works great with a PC, and it’s been really helpful to debug several projects to date. It uses the Logic software from Saleae as hinted by the label on it, although I am not sure if the device is supposed to be a cheap knockoff […]
