FreeRTOS includes a nice feature to give me information about how much time every task is spending running on the system:
FreeRTOS Runtime Information
This tutorial explains that FreeRTOS Runtime Statistics feature and how it can be turned on and used.
Switzerland has many lakes, the “4-Lake Hike” in the Jochpass region is probably one of the most beautiful hikes in the central part of Switzerland: beautiful flora, stunning mountain and lake views in the mighty Mt. Titlis area.

NXP has just released the 10.2.1 update of their flagship Eclipse based IDE. While the number increase from 10.2.0 to 10.2.1 indicates a minor release, there are a several things which make me move over to that new release.

My usual workflow is: edit – build – debug and repeat. And this for the same project again and again. So here are a few tips how to make these iterations faster with Eclipse. One thing is to use the F11 shortcut to debug the last launched/debugged application:

The McuOnEclipse GitHub repository hosts many Processor Expert projects and is very popular (cloned more than 1000 times, thank you!). Processor Expert is a powerful framework which generates driver and configuration code, simplifying application development for a wide range of microcontroller and families. But Processor Expert won’t be developed further by NXP and is not part of MCUXpresso IDE. While it is possible to install Processor Expert into MCUXpresso IDE 10.2, how can these projects used ini an IDE *without* Processor Expert? This article describes how to port an existing Processor Expert project into the NXP MCUXpresso IDE.

It is summer time in Switzerland, and the best time of the year to hike in the Alps and mountains. This time I’ll share with you our journey around the Glattalpsee (Lake Glattalp). Expect stunning views of Swiss mountains, flora, fauna and curious critters:

It is never too early to start thinking about Halloween projects :-).

When I ordered originally the MIMXRT1050-EVK from Mouser, it was without the LCD display (see “MCUXpresso IDE V10.1.0 with i.MX RT1052 Crossover Processor“. I ordered the LCD for the board soon after writing that article, but I was too busy with the university lectures and exams to get a hand on it. Finally I have spent a few hours at night and I proudly can say: the display is working 🙂
How can I open a project folder location in the system explorer?
Starting with Eclipse Oxygen, the project properties have a button for this in the Resource settings:

By default, the NXP S32K144EVB and microcontroller is using a 5V supply voltage and logic levels which is great for noisy environment or any 5V devices. Many of my displays and sensors use 3.3V logic levels, so I would have to use a level shifter from 5V to 3.3V. There is another way: to change the board for 3.3V logic levels so I can use directly things like a SSD1306 display.

In “Tutorial: FreeRTOS 10.0.1 with NXP S32 Design Studio 2018.R1” I showed how to use a custom FreeRTOS with the S32 Design Studio (ARM). The OSIF (OS Interface) provides an operating system and services abstraction for the application which is used by other S32K SDK components:
