Here at The Hackshed, we have several “retro” computers. A few of the machines we own are Atari STs. While looking at a couple of them the other day, I found one has a key missing (it was like that when we got it) and another had a faulty floppy drive. There was only one…
Something we’ve been working towards is building a homebrew CPU from scratch in CPLD. If you’ve seen any of our “Getting Started with CPLDs” guide, you might have noticed that we’re working towards completing the ALU before we can start adding proper CPU features to it. This article is less about the CPLD side of…
In this guide, we’re going to build up from the previous guide and add a button to our LED. Hopefully by now you’ve had a play with the Quartus II software and had a look through some of the logic elements in the library so I wont be explaining everything in minute detail. You should…
Before we get stuck in to the build, we need to take a look at resistor values. An LED will suck as much current from the CPLD chip as it can but what if your CPLD can only supply so much? The most likely result will be a dead pin on the chip. We don’t…
Ok so you’ve got your Quartus II software installed and you’re ready to start programming. I should note at this point that I will only be covering the schematic entry method of programming your CPLD. I will not be covering Verilog or VHDL in this guide. Let’s start by running Quartus II and taking a…
Here at the Hackshed, we’ve recently purchased a CPLD board based around the Altera Max II EPM240 chip. The board we ordered is a cheap LC Tech product from Ali Express. On reflection, perhaps we should have ordered a better board from a well known company as our board came with no documentation of any…
This one is for the Spotify people. We’ve created a small project that makes use of the Arduino and LCD Keypad shield to create a Spotify remote control. This will show the current playing song as well as adding Play/Pause, Prev and Next functionality to it. Check out the quick YouTube video at the bottom…
We’ve had the Intel Galileo for around three weeks now and tested a number of projects on it’s platform. This article will be a quick review and some instructions to get you up and running with your Intel Galileo! There are more and more distributors now stocking the Galileo; we got ours from RS Components…
Whilst browsing Kickstarter we came across these MicroView Ardunio’s which is an Arduino with a built-in OLED Display; as well as providing downloadable libraries for quickly displaying text, sprites, graphs and gauges on the OLED. The Microview has already reached it’s pledge goal with 27 days remaining (at the time of writing this post) We…
One of the best features about the Intel Galileo is that it has an mPCIe expansion port for adding various cards to it. One of the cards you can add is for connecting to your wireless network. The steps below should get you up and running with connecting your Intel Galileo up to your network…
