In many sources I have ‘inactive’ code: source code which is disabled by some macros or defines. Eclipse is great to ‘gray’ out the inactive parts using its Indexer, but they still need screen real estate:

Don’t get me wrong. I love a good slow-smoked and true BBQ pulled pork shoulder just as probably everyone else out there. And I love the babysitting (aka beer drinking 🙂 ) while the shoulder gets that incredible taste inside the smoker. But my workload for this weekend is insane high with all the university exam and grading work. My family loves that pulled pork too, and I knew upfront that I would not have the time to check and handle the smoking process for 12-18 hours (see “Easter Weekend Apple Juice Brined Pulled Pork Smoked on Beech Wood“). So I decided to prepare pulled pork the ‘easy’ way: Using a Sous Vide cooker and then use a normal oven to finish it. So it was an experiment, and the result is interesting:

I like to have as many lines of source code visible on my notebook or desktop monitor. And I think I have found a good balance between font size and readability.
On the other side: I’m getting older and my eyes are not getting any better. At the same time I noticed that students start using these ‘high-resolution-retina-displays’. They are great, but result in tiny default system fonts, so I have a hard time to read the source code on their machines.
Another challenge I noticed are the high-resolution projectors in class rooms or conferences. They are not well suited to show source code or text files because of the tiny fonts. Starting with Eclipse Neon there is an awesome feature which I can use to dynamically increase and decrease the font size which solves that problem:

The GNU tools include powerful utilities to collect coverage information. With coverage I know which lines of my code have been executed, which is a very useful test metric. The GNU coverage tools are commonly used for Linux applications. But to my surprise not much for embedded application development, mostly because it requires a few extra steps to have it available? Why not using free and powerful tools for improving software quality? This article explains how to install the GNU gcov tools into the Eclipse IDE.

In “Cycle Counting on ARM Cortex-M with DWT” I have used the ARM DWT register to count the executed cycles. With the MCUXpresso IDE comes with a very useful feature: it can capture the ARM SWO (Single Wire Output) trace data. One special kind of trace data is the ‘cycle counter’ information which is sent through SWO.

The spring university semester is coming to an end, and the Infotronic course closed with a Sumo robot challenge. Great challenge, new technologies, innovative approaches and funny designs 🙂

If I open a new workspace in Eclipse, it shows me the default ‘Welcome’ view:

During Embedded World 2017 in Nürnberg I was lucky to get a handful LPC800-DIP boards. To get all students who were lucky to get one, here is a tutorial to make that very exciting ‘blinky’ application on that board:

Eclipse for C/C++ (CDT) offers two different ways to get out of a debug session: Terminate and Disconnect:
Terminate and Disconnect
The terminate and disconnect behaviour is not standardized, and varies between Eclipse distributions and debug connection. This article is about how things are handled in MCUXpresso IDE, and how I can influence the behaviour.
I’m using Eclipse based IDE’s to develop and debug my embedded applications. This works great, as Eclipse has all the necessary tools to edit, build and debug it. But when it comes just to download/flash a binary to the board, then things are pretty much specific to the tools used. With the advent of the new MCUXpresso IDE, here is how that Eclipse IDE can be used for this.
