About a year ago, on December 7th 2015, Freescale and NXP have announced the completion of their merger. Now it is Qualcomm which wants to acquire NXP? It looks like these mergers are happening faster and faster. The reality is that merging products take more time than anticipated, and nearly one year later I can see the outcome of what comes out of the marriage between Freescale and NXP or between Kinetis and LPC: NXP has announced the MCUXpresso software and tools for Kinetis and LPC microcontroller:
The year is coming to an end, the Holiday season is approaching. In case you are looking for a nice present: I have completed my version of a sand clock: a clock writing the time into sand:
If you are interested to build your own version, I have documented the different steps with tips and tricks…
The good thing with failure is: it is an opportunity to learn :-).
So here is a case: For a STEM roadshow (see “MINTomat: World’s Most Complicated Bubble Gum Automata?“), we have produced in a rush an autonomous robot with a shiny printed 3D cover:
How to fascinate kids for technology? Show them that engineering is fun :-). At the Lucerne University of Applied Sciences and Arts we have created the ‘MINTomat’: a robotics system for STEM activities rewarding interaction with bubble gums:
Yes, pretty over engineered compared to a normal bubble gum automata, but that’s part of the fun :-).
This post is a bit off-topic. No, this is not one of my deep technical tutorials. It is not about all the muddy bits in hardware, and it is not about shiny and great tools. This post is about you all: WordPress counted 15’000 comments for McuOnEclipse!
Happy Commenting 🙂
PS: special thanks to Kevin P. and Jim T.: this blog would not exist without you!
It seems to me that not many developers use hardware trace? ARM indicates that maybe only <5% of developers are using trace. Too bad! Why are all the ARM Cortex microcontroller vendors putting a powerful hardware (and complicated!) trace engine into their devices, if only few developers are using it? Seems like a waste of silicon and an unnecessary price adder? Well, hardware trace can be a life saver: Because only with hardware trace the most complicated bugs and problems can be solved. And maybe because only the best are using it ;-).
‘Inversion‘ is an interesting meteorology phenomena: normally the air temperature gets colder the higher you get up in the mountains. With the inversion situation it is the other way round: cold air in the lower areas building a sea of fog, and warmer air and sunshine up above. Perfect for a hike, so sharing pictures from last weekend.
The first one is from the Haggenegg in Canton Schwyz, with the view to the South:
With the GNU compiler and linker I can place variables into custom sections (see “Defining Variables at Absolute Addresses with gcc“). This article is about how to get the section start and end address so I can for example access that range in my code. Or in general ways: how to use symbols defined in the linker script accessible in the C source code.
