After a lot of time spent coding, here’s the new release of Miosix, my OS kernel for microcontrollers. New features include: Porting for ST’s Cortex M3 microcontrollers Preliminary implementation of the POSIX thread API (pthreads) Improved statistics on memory usage and debugging messages Bug fixes and other enhancements If you’re interested, download the new release [...]

This summer I finally found some time to fix my power supply. It’s a rather old but relieable unit, and I have no intention of replacing it. Basically, it still works except for the voltage meter on the front panel. Over time, the pointer developed an offset of around 1V, which is visible in this [...]

Because of an issue with the hosting service, my website (together with other websites on the same provider) has been unavailable for three days. Now the problem is fixed and I’m back online.

Ever thought that you can make a torch using a glue stick?
Ever thought that you can hack an inductor into a transformer?
Here is the final result of a rather old project I’ve done in 2005, but never published until now.

Update Jun 22, 2011 : Fixed a bug for compiling under visual studio 2010. This is intended to be a small add-on to the article I’ve posted on my website which explains how to use boost’s asio library to interface with serial ports from C++ code. This blog post focuses on a topic not covered [...]

Over time, I find myself more and more interested in CMake. That’s because I write many little programs, and those that use makefiles routinely break as I switch OS. The last one was a program that depended on libpng. When I tried to compile it on Mac OS X, it failed to find the library. [...]

It took some time but finally someone put on the web images of what’s inside the Fonera 2.0N. Here are the links: Printed circuit top Printed circuit bottom Now some details: In the top picture you can clearly see the new Ralink chip and the FLASH memory, which has a parallel interface (the previous Foneras [...]

I posted a new article on my website.
It talks about a performance optimized and high level way of handling STM32 GPIOs using Template Metaprogramming.

It’s not the first time I talk about CMake in this blog, for the introduction read here. Now it’s time to explore the CMake syntax further. The first CMakeLists.txt looked like this: cmake_minimum_required(VERSION 2.6) project(HELLO) set(HELLO_SRCS main.cpp foo.cpp) add_executable(hello ${HELLO_SRCS}) As already explained, it successfully creates an executable called “hello” using the main.cpp and foo.cpp [...]
