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.
A beautiful trail high above the timber line, spectacular views over the Saas Valley in Switzerland, this is the “Almageller Höhenweg”. The Saas Valley is located in the Canton Wallis in Switzerland, on the border to Italy.
Part of the hike is not for faint-hearted, but very spectacular.
Continue readingThis 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.
Continue readingThis 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.
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.
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.
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.
Continue readingG-Code (or RS-274) is a widely used protocol for CNC machines. I have added vinyl cutting capabilities to the Shapeoko desktop CNC recently (see DIY Vinyl Cutting Drag Knife for Desktop CNC), however cutting vinyl with a drag knife is whole different story compared cutting materials like wood or aluminum. As with many other things, it is about handling all corner cases properly.
Among the many wonderful things that nature can provide, I love to watch damselflies flying above the water. It is pretty hard to catch one of these insects, but today I was lucky to capture one of these shiny predators:
Damselflies are similar to Dragonflies, but smaller and have slimmer bodies.
Happy flying 🙂
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:
