To celebrate the end of that sunny weekend, we smoked tuna and salmon with a simple soy-based brine:

Adding GNU Coverage Tools to Eclipse
The GNU tools include powerful utilities to collect coverage information. With coverage I know which lines of my code have been executed, which is a very useful test metric. The GNU coverage tools are commonly used for Linux applications. But to my surprise not much for embedded application development, mostly because it requires a few extra steps to have it available? Why not using free and powerful tools for improving software quality? This article explains how to install the GNU gcov tools into the Eclipse IDE.

Enzian

The Enzian belongs to the gentian family (Gentianaceae). This one shows the Clusius-Enzian which can be found up to 2800 m in limestone areas. The deep blue makes it a special flower. It is protected by law, but can be found in many places in the Alps.

Using Python to Store Data from many BLE Devices
BLE (Bluetooth Low Energy) sensor devices like the Hexiwear are great, but they cannot store a large amount of data. For a research project I have to collect data from many BLE devices for later processing. What I’m using is a Python script running on the Raspberry Pi which collects the data and stores it on a file:

DIY USB HID Joystick Device and Game Controller
For many projects it would be cool to build a custom USB Joystick device, either as custom game controller for Windows or any USB host which can be used with a USB Joystick. Instead buying one, why not build my version? All what I need is a USB capable board, some kind of input (potentiometer, push buttons) and some software, and I have my USB Joystick:

ARM SWO Performance Counters
In “Cycle Counting on ARM Cortex-M with DWT” I have used the ARM DWT register to count the executed cycles. With the MCUXpresso IDE comes with a very useful feature: it can capture the ARM SWO (Single Wire Output) trace data. One special kind of trace data is the ‘cycle counter’ information which is sent through SWO.

2017 Spring Semester Sumo Challenge

The spring university semester is coming to an end, and the Infotronic course closed with a Sumo robot challenge. Great challenge, new technologies, innovative approaches and funny designs 🙂

How Trees grow on Trees

I have been busy with too many things, so I apologize: no techy blog post this weekend. But what I can share is a unique wonder of nature encountered during a bike trip today at the end of the Klöntalsee:

3D Printed Sumo ToF Blade
ToF (Time-of-Flight, see “Tutorial: STMicroelectronics VL6180X Time-of-Flight LIDAR Sensor“) sensors are fun: they measure the time the light takes to travel to an object and back again. That way they can measure the distance to object with a millimeter accuracy. An ideal sensor for a battle robot: 🙂

Customizing Welcome View and Splash Screen in Eclipse Neon
If I open a new workspace in Eclipse, it shows me the default ‘Welcome’ view:
