In “Spilling the Beans: Endless Loops” several ways of creating and using endless loops were discussed. In this ‘bean’ it is about how to exit or break a loop.

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.
MCUXpresso IDE 11.4.0
University exam grading are all done now and results are in the system, and it is already time to prepare for the fall semester. I always try to use the latest and greatest tools in my courses, and the NXP MCUXpresso IDE 11.4.0 just came out. So time to have a look and explore the changes and features.
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.
Round MetaClockClock
It has been a while since my last MetaClockClock, and with the continued shortage of electronics on the market I had no chance to order new parts. But I still had some remaining parts, and with the modular design of the ’round’ clocks I was able to build up another one, but this time with even less than the usual minimum of 24 clocks:
So if you are up to build a MetaClockClock with less clocks, this might be the way for you.

A desktop CNC is a great addition to any 3D printer or laser cutter. I consider them ‘the trinity’ for any maker garage. While a desktop CNC is great for wood and some metals like aluminum or brass, it would be great to extend the infrastructure with something more: vinyl cutting. And with this the idea to have cool sticker on my laptop lid:
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…
