Wireless Time-Triggered Communication using a Firefly Clock Synchronization Approach

In South-East Asia, huge swarms of fireflies synchronously emit light flashes to attract mating partners. The underlying principle can be used to implement a robust and scalable distributed synchronization approach in wireless sensor networks. In this work we implement the … Continue reading

Reading thousand sensors in the blink of an eye

A cyber-physical system is formed by a network of interacting sensors and actuators. With the availability of small inexpensive sensor elements, such a network may contain thousands of interacting sensors. This makes such systems a little bit similar to biological … Continue reading

Efficiently detecting a frequency using a Goertzel filter

The Goertzel algorithm detects a specific, predetermined frequency in a signal. This can be used to analyze a sound source for the presence of a particular tone. The algorithm is simpler than an FFT and therefore a candidate for small … Continue reading

An Orchestra of Bits and Bytes: Time-Triggered Advanced Driver Assistance Systems

Multi-sensor object tracking is an important feature for advanced driver assistance systems in future automobiles. Most state-of-the-art systems cannot guarantee deterministic processing of the sensor values due to unsynchronized sensing and processing units. To overcome this shortcoming we propose a … Continue reading

An alternative UART that does not need special quartz frequencies

A UART (Universal Asynchronous Receiver/Transmitter) is a component that transmits chunks of data (typically character size, i.e. 7 or 8 bits) onto a serial communication line. Almost every microcontroller features at least one UART component, that can be configured to … Continue reading
