Besides all techniques created until today, every software developed can have bugs. Computer software nowadays can be easily updated to a new versions to fix all those bugs and it doesn’t take anything more than a few mouse clicks. Embedded software ou bare bone firmware can have bugs too, but update to new versions is not always that simple as in computers software.
Hi,
Today is a small how to install OpenCV + QT5 in linux Ubuntu. For those who doesn’t know what is OpenCV, you can check here. Briefly OpenCV is a library for real time image processing created by Intel. It’s free for use under BSD license. Continue reading Installing OpenCV 2.4.9 + QT5 in Ubuntu
Hello!
Today I’ll explain a little bit about unit tests, test driven development (TDD) and how to set up an environment to be able to use TDD concepts in Microchip microcontrollers. Continue reading Test Driven Development – Unity + Microchip
Hello there!
This post is about ordered dithering in Octave. What’s is dithering? You can find a very good explanation here in wikipedia. But briefly, the idea of dithering is to create the illusion of color depth in images with (in our case) only two color quantization. This technique is used in printers, scanners, etc. We print small dots black and leave white spaces and our eyes will do the rest of the job. For those who doesn’t know, our eyes has a low pass filter as frequency response.
Hello there!
Here a simple “how to” to install packages on Octave.
Hello there,
This post is a little different of I’m using to write, but yet very useful for us engineers! It’s about how to compile octave to be able to load 16 or 32 bits colour images. First of all, what’s Octave? Continue reading Compile Octave 4 using 16/32 bits colour – Ubuntu
Hello there!
In this post I’ll show how to set up your IDE to debug the STM32F0 discovery board using open source tools. Continue reading STM32F0 discovery + GCC + Eclipse + OpenOCD + Ubuntu – Part I

Hello people,
As I said, I’m studying FPGA/VHDL and for that I have a spartan 3E demo board from Digilent. It’s a very nice demo board and it has everything that it takes to program the FPGA (no need of special cable). Continue reading Spartan 3E demo board
I'm an electronics engineer with 10+ years of experience in embedded system, hardware and firmware development for several 8/16/32 bits microcontrollers like 8051, Microchip, MSP430, Freescale, ARM, etc. I'm a passionate in electronics and embedded systems, but not a nerds! =P
