After having imported the repository with the SDK, it is now time to create a first project.

VS Code: MCUXpresso SDK Repository
In a previous article I have installed the MCUXpresso extension and used the MCUXpresso Installer to install the necessary development tools.
In this article I’m going to import the SDK.
Laser-cut MCU-Link Pro Enclosure for the Masses
With “Adding RGBW Wings and Enclosure to a Debug Probe” I have a really shiny enclosure for the MCU-Link Pro Enclosure.
But I did not had enough time to replicate this for a full set of classroom hardware. The original card boxes from NXP showed already after one semester severe wear, so I have to setup something more robust: a box to store all the cables, and an enclosure to protect the PCB, for 40 units.
3D printing would take to much time, so I ended up with buying storage boxes and creating an laser-cut acrylic (PMMA) enclosure for the debug probe itself:
Assigning Nicknames to Debug Probes
Dealing with and debugging distributed systems, I end up with multiple debug probes and target boards on my desk. When starting a debugging session, it can be hard to identify a debug probe by its serial number. What I do in such a situation: put a color stick on the debug probe and have it assigned a nickname.
That nickname then shows up during the debug connection, and I’m sure I connect to the right probe and board that way.

VS Code is managing its extensions (see VS Code: MCUXpresso Extension). But to make it usable for embedded development, you need more tools: compiler, linker, debugger, libraries, build system, debug probe support, …
For the experts, this is not a big deal: you know where to get them, and you install them, as shown with another tutorial. But for a class full of students or newcomers to VS Code, this can be a a time consuming and daunting task.
To make the installation easier, NXP has released a ‘dependency checker and installer’ along with their VS Code extension, which makes the setup much easier and simpler.
VS Code: MCUXpresso Extension
In essence, VS Code is only a text editor, although with very nice features. An editor which can be enhanced with so called extensions. With the right set of extensions, VS Code can be specialized for web development, or even LaTeX documenting. Or as in the case of this article series, for embedded development.
MCUXpresso IDE 11.8.0
Don’t worry: despite all the things going on with VS Code, Eclipse is here to stay probably for many more years. The Eclipse foundation is pumping out releases, and so does NXP with their latest MCUXpresso IDE 11.8.0. Lets have a look…
RS-485 with NXP LPC55S69
I’m using the RS-485 field bus in many of my projects: it is very reliable and robust, and easy to implement. And with ModBus there is standardized protocol used in building automation or industrial control applications. For example I’m using the protocol to communicate between battery systems and an EV Charger.
In this article I show you with an example, how the NXP LPC55S69 can be used with RS-485.
Continue readingUsing Legacy Devices with LinkServer
The Freescale K20DX128 MCU was one of the first ARM Cortex-M devices of that company (now NXP) back in 2012, and the FRDM-K20D50M board was the first ‘FRDM‘ board of a long and successful series of boards, starting back in 2013. I still have the K20 present in many of my designs. The challenge with ‘early’ or ‘legacy’ devices is that after a while, they are ‘not recommended’ any more, and it is hard to get support for them. So for example in newer tooling and software from NXP, there is no support for the K20.
So if you still have the K20 around, and need some newer tooling, then I have good news for you: It is possible to add that good-old-Kinetis to the list of supported LinkServer devices, so you are not stuck and can use newer debugging solutions for the K20.
Continue readingData Converter for MCUXpresso Energy Measurement Data
The combination of the NXP MCUXpresso IDE with the NXP MCU-Link Pro debug probe implements a nifty power and energy measurement tool (see New “MCU-Link Pro”: Debug Probe with Energy Measurement). The eclipse based IDE provides a dedicated view to inspect the data collected. It can export and import data, but it is in a binary format. In this article I present a way to export and then convert the data into .csv or any other format for processing or visualizing it in different ways.
Using an open source command line tool, the binary data gets converted into a csv format, which then can be consumed by many tools, e.g. gnuplot.
