MCUXpresso IDE V11.3.0 for 2021

I’m in the middle of the university exam season: means writing exams and do grading. The same time the new semester is approaching too and I need to prepare the new course material. For the classes using NXP parts I’m using the Eclipse based MCUXpresso IDE, and I just received the announcement that a new version V11.3.0 is available: time to check out what is new.

Eclipse Indexer Debug Tips

Eclipse includes a background parser called ‘Indexer’ which is used to assist the developer with various kind of information, for example jumping to a variable declaration or definition. Basically it is a parser running in the background collecting information about the sources and building up that ‘index’ data base.

3D Printed Mounting Bridge for Feller Smart Light Control for Philips Hue

The company Feller sells a wall mountable ‘Smart Light Control’: this provides 4 push buttons compatible with the Philips Hue system (on, off, dimming, etc). Unlike many other remote controls and buttons it is a great design and available in different colors. Feller does have a ‘classic’ wall switch series too, so this one is perfect to replace or augment an existing installation and make it ‘smart’.

MetaClockClock V4 for the Year 2021

I had a few of PCBs left over from the V3 MetaClockClock, and originally I planned to finish a build with them by the end of 2020. But as always: things took a bit longer than expected, so I finally finished it today on the first day of the year 2021.

The build uses the same hardware as in the previous V3, but instead of an ‘artistic’ canvas background I decided for a more natural and wood design:

Eclipse CODAN (Static Code Analysis) for C/C++

The Eclipse CODAN (Code Analysis) plugin is part of CDT and is a powerful static analysis tool finding all kind of possible bugs and issues. Still to my surprise not many C/C++ developers take advantage of it maybe because they are not aware that it exists?

In this article I show a few tips how to effectively use it, especially with the NXP MCUXpresso SDK.

New MetaClockClock V3 finished with 60 Clocks

The holiday break at the end of the year is always a good time to finish projects started during the year. This one is about my ‘MetaClockClock’ Version 3.

OpenOCD with MCU-Link

The NXP MCU-Link is a powerful $10 debug probe for ARM Cortex-M devices and works with the NXP LinkServer for debugging. The LinkServer does not an implement a gdb server, so it limits its usage e.g. for scripting or command line debugging. But as MCU-Link is also a CMSIS-DAP compatible debug probe, I can use it with OpenOCD which is open source and implements a GDB server. This article shows how I can use it with the MCU-Link.

Just before the Snow

It has been snowing down to the lower areas in Switzerland the past days: Winter finally arrived in my area. So I consider last weekend the ‘weekend before winter’, at least in a meteorological sense. And because it was a wonderful ‘inversion’ situation with fog below and sunny sky above, it is a good time to share a few impressions.

Standalone and Command Line Programmer with MCUXpresso

The MCU-Link is a $10 CMSIS-DAP capable debug probe which works out-of-the box with the MCUXpresso Eclipse based IDE. This is great for development, but how can I programming with the push of a button or a script? The answer is no: there is an easy way to use the debug probe outside Eclipse from a shell script, and you can use that MCU-Link probe to do the job. This is especially useful as with the example below where I have to program 60 boards this week-end :-).

Configure hidden and internal Shortcuts in Eclipse

A very useful feature in Eclipse is Ctrl+Shift+L which lists all the available shortcuts:

Pressing Ctrl+Shift-L again will open up a dialog where I can configure them. But what if the shortcut or action is not listed there?
