Flip-Dot Clock using Used Bus Parts

I always have been fascinated by electromechanical stuff like these Flip-Dot Displays.

Placing Code in Sections with managed GNU Linker Scripts

Managed linker scripts are great on one side: the simplify the otherwise complex GNU linker script handling. On the other side it requires knowledge how to tweak them in case ‘non-standard’ behavior is needed.

SWO with ARM Cortex-M33

One major concern of embedded system development is performance. Microcontroller have more MHz than in the past, but embedded applications are all about timing and real-time aspects.

The challenge is: how to get data off the target in realtime? SWO can help with this….

Upgrade to a new NXP MCUXpresso SDK

As time flies by, my projects are evolving. My lab projects get used over multiple semesters, and the MCUXpresso projects by default use the SDK version used at that time.

This is great because I do want to have control over what SDK is used. But from time to time it makes sense to upgrade a project to a newer version. In this post I’ll show how an existing project can be upgraded to use a new SDK.

Attach with the Debugger to a Running Target

Sometime I’m pretty sure I wrote about a topic I can find or refer to, and I was pretty sure I did write about ‘attaching to a running target’ using MCUXpresso IDE in an article, but Google does not find it? The only rational outcome is that I can blame Google and I have to come up with a potential duplicate ;-).

Anyway: attaching to a running target is such an essential life saver it deserves a dedicated article.

Play a Sound at the End of the Build with Eclipse

Using Post-Build feature in Eclipse is a great way to augment a build with all kind of actions. What if the build takes a long time and you want to get notified? One way is to play a sound at the end of the build process.

Enhancing Binary Utilities in MCUXpresso IDE

The NXP MCUXpresso IDE has a nice context menu for executing different actions on a binary in the Eclipse Project Explorer View:

Binary Utilities

What it makes it even nicer: I can configure and use it to do anything I like. For example I can convert files and copy it in one action.

Using Linux Shell Commands on Windows with MCUXpresso Pre-/Post-Build Steps

In “Touch & Build: Auto-Update of Firmware Date and Time” I’m using commands as ‘touch’ in a pre-build script with the NXP Eclipse based MCUXpresso IDE. That ‘touch’ command is not a Windows shell command, but common on Linux: it updates the time/date of a file.

As a Windows user you might wonder what is about this ‘Linux compatible shell’?

Touch & Build: Auto-Update of Firmware Date and Time

It is very valuable to have a date and time information in the binary. That way for example using a shell I can check the version of the firmware running on a device, or it can be printed on a console or UART as needed.
