    Web-based Overview

    When operating and debugging multiple instances at once, I like to have all information in one place – next to each other. Therefore, we implemented a web application that displays the current quaduinos status and internal database information. On the right hand, you can see the webcam image that shows the build and 4 LEDs. […]

    Technical Principle

    The Quaduino quadruplex system consists of four individual computing lanes that synchronize and and exchange data. Single Computing Lane Each computing lane consists of an Arduino Mega2560: The software is flashed on each single lane and in principle each computing lane can perform its own services. To allow redundant execution of functions, the lanes have […]

  • Quaduino: What is that?

    The Quaduino is a combination of four Arduino micro-controllers that form a so-called quadruplex system. It originates from the lecture „Systementwurf“ held at University of Stuttgart / Institute of Aircraft Systems by Prof. Reichel. Within this lecture, he presents how to design safety-critical aircraft systems and shows one implementation of a quadruplex avionics system. The […]
