Bit by the bug, a few days later

So, I got #BitByTheBug. I posted something quick on Twitter and G+, and once again, thanks element14 for your support! Before actually showing this to anyone, the best thing would be to test it myself, and see what all the fuss is about. It looks cute, it looks well designed, and the website is pretty… Read More »

A gift from element14

Yesterday, I received a parcel. I was thrilled when I was it was from element14, so I opened it up to take a peek. They must have known that I moved into a new house a few weeks ago, and my new office is looking bare. Here’s what I got: Two stickers, a dancing man… Read More »

A few days with the SiFive HiFive1

A few days ago, I managed to sort out some shipping issues, and I finally got my hands on a SiFive HiFive1 board. This is something new, open source hardware, thanks to RISC-V. No, really. The MCU is open source, just go and grab the RTL files from their GitHub. Anyway, I’ve been playing around… Read More »


I’ve been teaching students of all ages, from 8 years old to adults, and one of the most common things I’ve heard is about bouncing. Sooner or later, we are faced with this rather simple problem, so what causes it, and what can we do? Let’s start off with a simple schematic. Press the button,… Read More »

STM32 Nucleo-F411RE

The Embedded World The world is getting smaller and smaller, and more and more connected. Computers used to take up an entire room and be reserved to an elite few. Now, nearly everyone has that much computing power in their pocket, and it hasn’t stopped yet. Microcontrollers are becoming smaller, yet more powerful. In a… Read More »

Time for a change!

After a few years of using Joomla, I’ve decided that it is time to change, and to use WordPress. While I do like Joomla, it is becoming increasingly difficult to configure the site the way I want it, which is a problem. I spent about 15 minutes yesterday trying to get an article to have… Read More »


My parcel has just arrived. To say that I am excited would be an understatement; I’ve been waiting for this, to the point where I was almost unhappy about enjoying a public holiday, because the transporter wouldn’t come. Even worse, my contact at NVIDIA sent me an email letting me know that the parcel was… Read More »

STM32F429I Discovery

The ST Microelectronics Discovery series are designed to show off the capabilities of the STM32 series. They come with numerous peripherals, and large amounts of I/O lines. The philosophy is to show the user what the device is capable of immediately, without the need to add any peripherals. The device that I am testing is… Read More »

ARM mbed Ethernet Starter Kit

Embedded systems are all about being lightweight, and only including what is really needed. This is sometimes the case for evaluation boards, but other times, evaluation boards come with multiple peripherals. This board is different, it comes with a large array of sensors and peripherals, almost as much as can fit on the board itself,… Read More »

emtrion SBC-SAMA5D36

I may be a microcontroller guy myself, but there are times where you need the power of a microprocessor. Having an operating system handle the memory, peripherals and events just saves time, and some applications really do need the power a microprocessor provides. Atmel’s SAMA5D3 family has some impressive devices. Based on ARM’s A5 architecture,… Read More »
