MCUXpresso IDE: Adding the Eclipse Marketplace Client

Posted on by
24

One great thing with Eclipse compared to proprietary IDEs are the thousands of available plugins. Yes, not every plugin is probably on the ‘must have’ list (I have listed some in a series starting with “5 Best Eclipse Plugins: #1 (Eclox with Doxygen, Graphviz and Mscgen)“).

The ‘traditional’ approach to install Eclipse plugins is using the menu Help > Install New Software. Using that approach, I have to use or enter an Eclipse update site. An easier way is to use the Eclipse Marketplace plugin which allows me to search and browse for plugins and simplifies installation of it. But as this one does not come installed by default with MCUXpresso. But it is my preferred way to browse and install plugins into Eclipse:

MCUXpresso IDE: S-Record, Intel Hex and Binary Files

This is another article about the NXP MCUXpresso IDE (see “MCUXPresso IDE: Unified Eclipse IDE for NXPs ARM Cortex-M Microcontrollers“), this time it is about Post-build steps. Post-build steps are custom actions which can be executed after the build (or link phase), and are typically used to generate S-Record, Binary or Intel Hex files (see “S-Record, Intel Hex and Binary Files“).

MCUXpresso IDE: Unified Eclipse IDE for NXPs ARM Cortex-M Microcontrollers

There are many mergers going on in the industry, and one of the largest one was in 2016 the integration of Freescale Semiconductor with NXP Semiconductors, with both providing Eclipse based IDE’s to their customer base. Consequently, the company merger triggered a merger of the IDE’s, and last week NXP has released the result: the MCUXpresso IDE.

Tutorial: Using Eclipse with NXP MCUXpresso SDK v2 and Processor Expert

Posted on by

To me, software and tools are by far more important than the microcontroller. Because the silicon is a ‘one time kind of thing’, where the software has to be maintained and working over a longer time. And at least my software usually needs to be ported to a new device, so portability and available software and tools are critical to me.

The combination of MCUXpresso SDK (formerly Kinetis SDK) and Processor Expert is unfortunately not supported by NXP. But I have found a way to get them work together in a nice way, and this article is about making that combination possible :-).

Embedded World Nürnberg 2017 Impressions: MCUXpresso, Hexiwear, NTAG, LPC800-DIP and Alan Hawse

This year I managed to attend the Embedded World in Nürnberg/Germany after missing the 2016 show. And 2017 has been a blast! With more than 1000 exhibitors and >30’000 visitors it was huge! There were too many exciting things, so I just pick a few: NXP demonstrated the new MCUXpresso Software and Tools with a new Eclipse Neon based IDE, lots of IoT and Hexiwear, the tiny LPC800-DIP board, and I have met Alan Hawse in person!

Better FreeRTOS Debugging in Eclipse

Posted on by

With debugging FreeRTOS applications in Eclipse, it is a big to have views available showing all the threads, queues, timers and heap memory allocation. One of the best Eclipse plugins are the one NXP provides for FreeRTOS: they are free of charge and give me pretty much everything I need. However, if you are not that familiar with FreeRTOS itself, here are a few tips to get more out of the plugins.

Zephyr: Thoughts and First Steps on the ARM Cortex-M4F with gcc, gdb and Eclipse

Posted on by

The concept of Linux (Open Source, broad developer base and broad usage) is a success story. While there is a lot of diversity (and freedom) in the Linux world, Linux is Linux and again Linux :-). And the world has (mostly) standardized on Linux and its variants on the high embedded system side.

On the other side, the ‘middle and lower end’ Embedded world is fragmented and in many aspects proprietary. So it was no surprise to me when the Linux Foundation announced the ‘Zephyr’ project back in February 2016:

“The Linux Foundation Announces Project to Build Real-Time Operating System for Internet of Things Devices. Open source Zephyr™ Project aims to deliver an RTOS; opens call for developers to help advance project for the smallest footprint IoT devices.“

Ζεφυρος (Zephyros) is the Greek good of spring and the west wind. Obviously this inspired the logo for the Zephyr project:
