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.

Spilling the Beans: volatile Qualifier

It is interesting to see that some aspects (mostly unintended) can stimulate lots of good and fruitful discussions. So this happened with “Spilling the Beans: Endless Loops” (recommended to read 🙂 where using (or not using) volatile for inline assembly created thoughts which warrant an article on that subject.

The volatile qualifier in C/C++ is misunderstood by many programmers, or wrongly used.

Spilling the Beans: Endless Loops

The university lectures are kind of ‘back to normal’: with the COVID certificates mandatory, many former limitations (social distance, masks, …) have been relaxed. So this means there are now many more questions and discussions with students.

One of the thing I realized is that I am doing things in a certain way, and I don’t need to think about it, because I have used certain techniques for a long time. So I had several discussions last week with students which I would characterize as “aus dem Nähkästchen plaudern”. No real ‘secrets’, but just things which might be a something new to think about. Well, I think this is worth a potential new blog article series if this continues, so here we go with a first one: how to write ‘endless’ loops in C?

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:

MIMXRT1064-EVK running ThreadX
MIMXRT1064-EVK

While this tutorial uses this specific board, things are pretty generic and should be applicable for any other board or MCU.
