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 🙂
In my earlier post “Tutorial: Web Server with the ESP8266 WiFi Module” I used the ESP8266 WiFi module to run a local web server. This is a cool way to control devices inside my network. But to use that web page from the internet, I would need to open up my router which I don’t want to do for obvious reasons. Why not going the other way: host the web page in the internet, and have my board communicating with that internet page? This is exactly what this hype around IoT (Internet of Things) is all about :-).

Over the last weeks, several contributions, extensions and fixes have been added to the McuOnEclipse components, so a new release is available on SourceForge.

Travel is a hassle these days: airline on strike in Europe, long security lines at the airport, bumpy flight and long transfer to the hotel which is so tiny that the taxi driver missed it twice! Anyway, at least this time the reservation of the room *did* work. Arrived completely tired and with notebook batteries drained and empty. Unpacked the power adapter, ready to charge it up. Only to realize that the notebook power supply cable does not match the travel adapter plug! :-(:
Travel Power Adapter Mismatch
So I have packed the 3-pin notebook power supply instead my usual travel 2-pin one 😦
It has been a while since my first post about the ESP8266 (see “Cheap and Simple WiFi with ESP8266 for the FRDM Board“). The ESP8266 is a new inexpensive ($4.50) WiFi module which makes it easy to connect to the network or internet. Finally this week-end I have found the time to write up a tutorial:

In CodeWarrior there was a very useful feature in the CodeWarrior Projects view: with a context menu I can open that folder/file in Windows Explorer:

However, this feature is missing in Eclipse, so how to add this functionality?
