Finally, winter with lots of snow arrived in Switzerland. Getting up at 5am this morning to free up my front yard from the 25 cm snow which came down overnight, so I can drive my wife to work. She does not like driving in snow conditions, but it is fun for me :-). But lots of snow, I thought I could use a little helper bot:

This post is overdue, as it is about the McuOnEclipse components which have been released already a few days ago. The highlights are (beside smaller updates and bug fixes):

The FRDM-K22F is one of the latest members of the Freedom board families: 512 KByte Flash, 128 KB RAM and the usual Freedom board components on it. Unfortunately, Freescale decided not to populate the micro-SD card connector on the board, so from this perspective the FRDM-K64F is more value for the money. But the board has USB, so this makes it still interesting. And this is what this post is about: Adding USB to the FRDM-K22F board in a few minutes…

The great thing with open source tools like Eclipse and GNU (gcc, gdb) is that there is a wealth of excellent tools: one thing I had in mind to explore for a while is how to generate code coverage of my embedded application. Yes, GNU and Eclipse comes with code profiling and code coverage tools, all for free! The only downside seems to be that these tools seems to be rarely used for embedded targets. Maybe that knowledge is not widely available? So here is my attempt to change this :-).
Or: How cool is it to see in Eclipse how many times a line in my sources has been executed?

And best of all, it does not stop here….

As I have received multiple questions about that Darth Vader Santa Claus/Christmas robot in the Mini-Sumo competition last week, here are the details in case you want to build your own :-)…

In Eclipse and CDT, I need to tell the compiler where it has to search for the header files. The normal way is to go to the compiler settings (menu Project > Properties > C/C++ Build > Settings) and then add the include paths, one by one, using the ‘+’ icon:
Adding Include Path (shown using the GNU ARM Eclipse plugin)
But for many include paths, this is a time-consuming process. But there is another way.
Here are the videos and results of the Mini-Sumo competition held on 19-Dec-2014 in Horw, Switzerland:
See “Infotronic WS2014 Sumo Robots are Ready!” for all the robot portraits.

The Sumo robots are ready to battle today!
The team at the Autonomous Systems Lab under Roland Siegwart has produced the 2014 Robotics Christmas video, enjoy!
Happy Christmasing 🙂
