Latest changes include preliminary support for the STM32F4 microcontrollers, and the stm32f4discovery board.

What if you have a graphic display without an embedded controller, and you want to drive it with an ARM microcontroller? Turns out that if a DMA is available, the task is not so impossible as it first seems.

Ok, here’s the new library for Miosix: Mxgui. As the name suggests, it’a a GUI library for microcontrollers, designed to work with the Miosix kernel.
Source code is here, while documentation here.
What can it be used for? 3D rendering on a …

When I first published this article about using serial port with C++ I didn’t expect it to become one of the main reasons people visit my website. Over time, thanks to many comments, bug reports and suggestion, the serial port classes have been modified significantly, to the point that releasing them in a .tar.gz file [...]

Some time ago I saw on Hack a Day this post about Le Dominoux, an electronic based version of dominoes. At first it didn’t seem much fun, but watching the video I quickly changed my opinion. In the end, the author also measures the power consumption of the device when the led is not lit, [...]

Even more rant this time. To go on programming microcontrollers as I’ve always done I have to disable two programs, gpsd and modem-manager (see my previous post) because hardware manufacturers fail. The first one, gpsd is done. To fix the second one without killing/removing NetworkManager I have to contact ModemManager developers. To do so I [...]

This title is probably not what you’d expect. Usually people complain for the opposite reason: they buy some hardware, connect it to Linux and it does nothing, so they have to spend time in forums to see what can be done even if manufacturers don’t officially support Linux. In my case, it’s the plug and [...]

This blog post is about png++, one of my favourite C++ libraries. It’s a wrapper of libpng in C++ that allows to handle PNG images so easily that you’ll never want to use bare libpng again. All you need to start is to add these two lines in you source files: #include “png++/png.hpp” using namespace [...]

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 [...]
