Header files in C/C++ are defining the interface between different modules. In this article I share some tips and tricks how create such interface files.

Visual Studio Code for C/C++ with ARM Cortex-M: Part 10 – Assembly Stepping
The Microsoft Visual Studio Code is a great IDE, but does not (yet?) implement features for true embedded usage. Or things are there to some level, but hard to use. One of these things is how to step in the assembly code. This article shows how to do this.
Custom C/C++ Headers with Eclipse
One of the great things in Eclipse is that it can be customized down to the bits. The downside (pun intended) is that it might not be obvious how to do this. So here is how you can create your own custom file header when creating a new C/C++ file in Eclipse:
New “MCU-Link Pro”: Debug Probe with Energy Measurement
After the release of the NXP MCU-Link debug probe, there have been hints in the Eclipse based MCUXpresso IDE that there must be another one coming. And indeed: another and more powerful debug probe is now available: the MCU-Link Pro. It is not only a debug probe but a power/energy measurement tool too, including an extra LPC804 mikrocontroller which can be used for all kind of things, like automation or scripting.
Visual Studio Code for C/C++ with ARM Cortex-M: Part 9 – RTT
For me the Cortex-Debug Visual Studio extension by marus25 is the standard way to use VSC for embedded development. Another ‘standard’ piece I’m using in many of my projects is the SEGGER RTT.
Tutorial: GNU gcov Coverage with the NXP i.MX RT1064
This tutorial shows how to use and collect coverage data using the GNU gcov tool. As board and hardaware I’m using the NXP i.MX RT1064 EVK:
While this tutorial uses this specific board, things are pretty generic and should be applicable for any other board or MCU.

This is a new article in my series about using Microsoft Visual Studio Code: After installation, project setup, building, debugging, setting up a kit, IntelliSense and FreeRTOS. This one is about setting up and using the xPack Extension to build cross-platform-multi-tool project with a project manager.
Standalone SWO
SWO (Single Wire Output) in ARM cores is probably one of the most under-used features. Which is surprising, because SWO can be very useful. In a nut shell: SWO is a single wire output pin/signal channel which can provide lots of different data, like PC sampling for coverage information, interrupt tracing data or ‘uart-like’ text packets.
Position-Independent Code with GCC for ARM Cortex-M
Welcome to ‘Alice in Wonderland‘! For a university research project using an ARM Cortex-M33 we are evaluating position-independent code as way to load applications or part of it with a bootloader. It sounds simple: just add -fPIC to the compiler settings and you are done.
Unfortunately, it is not that simple. That option opened up a ‘rabbit hole’ with lots of wonderful, powerful and strange things. Something you might not have been aware of what could be possible with the tools you have at hand today. Leading to the central question: how is position-independent code going to work with an embedded application on an ARM Cortex-M?
Let’s find out! Let’s start a journey through the wonderland…
