Creating custom Expansion Board and Header for the MCUXpresso Pins Tool

Posted on by

The MCUXpresso Pins Tool is part of the NXP configuration suite which makes pin assignments, configuration and muxing easy. What I have somehow missed from one of the latest updates and releases is that it allows me now to add my own custom headers definition. Not only the tool is now aware of the ‘standard’ Arduino headers, but I can add my own headers too. This can be useful for providers of breakout boards or any kind of board which can be added to a MCU board. In my case it is very useful for projects where we design our own (breadboard-friendly) board or a custom board with an expansion board: we can design a board header and use it in other projects.

MCUXpresso IDE 11.5.0

I’m now in the middle of the university fall semester exam season with writing exams and grading student work, and the same time the new semester courses need to be prepared. With the global silicon and board shortage, this will be again a challenge to equip all the labs with the needed infrastructure. The good thing is that there is no shortage on software and tools side of the infrastructure: NXP released last week their new flagship Eclipse based IDE: the MCUXpresso IDE 11.5.0. Time to check it out for the upcoming lectures and classes….

Spoiler Alert: It has a new view for FreeRTOS lovers, plus new features for energy/power measurements!

Adding RGBW Wings and Enclosure to a Debug Probe

I’m using debug probes on a daily base. They have to be functional, and I value functionality over aesthetics. For cost reasons many debug probe vendors either only provide a bare PCB without enclosure, or the enclosure is made of simple plastic enclosure.

That’s OK. But when I received my NXP MCU-Link Pro debug probe, I wanted to add an enclosure for it: Not only to add protection,but to have it look cool too :-).

Upgrade to a new NXP MCUXpresso SDK

Posted on by

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.

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.

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.

MetaClockClock Build Instructions

Posted on by

If you are not aware (yet?): it looks like the COVID pandemic caused a global silicon and microcontroller shortage with lead times >50 weeks in some cases. The microcontroller I have used for the MetaClockClock build (see “New MetaClockClock V3 finished with 60 Clocks” and “MetaClockClock V4 for the Year 2021“) is affected by this too, but I had luck and still enough microcontrollers to build a few more boards.

So I still have enough for building a new variant with it (not finished yet). While everyone else is waiting for the devices to arrive, here are more details and instructions for your own build.
