From C to C++: Converting Eclipse C Projects
Creating a new project with Eclipse for a microcontroller these days is fairly easy, and I have the choice if I want to start the project with C or C++:
Choice of C and C++ for a new project
Still the embedded microcontroller world is dominated by C and not C++. So while it is easy to start with a C++ project, most vendor provided example or tutorial project are C projects. So how can I transform such project to C++?
How to use Eclipse CDT Environment Variables in C/C++ Code
When using a logging framework it is useful to use the current file name or line number. The ANSI C/C++ standard defines the __LINE__ and __FILE_ preprocessor macros for this.
But what about the project name, if it is a release or debug build, the microcontroller used or other things like the operating system which was used to build the binary?
Target Chip Name
This (and even more) can be easily provided by Eclipse to the C/C++ application being built with CDT.
How to get Data off an Embedded System: FatFS with USB MSD Host and FreeRTOS Direct Task Notification
This is a follow-up article of my earlier project presented in “FatFS, MinIni, Shell and FreeRTOS for the NXP K22FN512“. I wanted to extend it with a USB MSD (memory stick) device: The USB storage device gets automatically mounted, and depending on a configuration (.ini) file on the memory device I can perform various actions, for example automatically copy data from the SD card to the USB device. For example the system logs data, and to get the data I insert the memory stick, it copies the data on it and automatically unmounts it, and I can remove the memory stick.

Disabling NMI (Non Maskable Interrupt) Pin
The NMI is a special interrupt on ARM Cortex-M architecture: as the name indicates, it cannot be ‘masked’ by the usual ‘disable interrupts’ flags (PRIMASK, BASEPRI), similar to the Reset signal.

Dealing with the reset signal is kind of obvious, and most designs and boards have it routed to a reset button or similar. The NMI is less obvious if you don’t pay attention to it: most ARM-Cortex implementations and boards have the NMI signal routed to a pin and are ‘hiding’ it in the schematics behind a normal GPIO pin or port: if you don’t pay attention to the NMI functionality, the board might not work as intended.
Behind the Canvas: Making of “60 Billion Lights”
As promised I’m going to share more details about the “60 Billion Lights” project. It is about a project to build a piece of electronics behind a 100×50 cm canvas to show animations or to display information like temperature, humidity, weather, time or just any arbitrary text.
