Descrizione dell'insegnamento

Il programma dell'insegnamento è provvisorio e potrebbe subire delle modifiche

Knowledge in analog and digital electronic, C++ programming.

Overview

This course embraces themes of sensing and transduction, signal acquisition, design of analog/digital circuital blocks, analysis of embedded systems and an overview on rapid prototyping solutions for advanced electronic design. These are vital subjects for any system which extracts signals from the real world and processes the information digitally. The course comprises information on signals, sensor and transducer principles, related applications, embedded electronic design for signal acquisition and finally design and testing, by using a specific software, of an electronic acquisition board managed by a microcontroller. Also the course aims to provide an overview on the hardware and software platform related to Arduino prototyping board. By initially addressing the basic concepts related to Arduino board and IDE programming, the course introduces the Arduino hardware, its interfacing with sensors, components and accessories in order to give an overview on rapid prototyping solutions for Arduino-based electronic design. Furthermore, the principles of ATMEGA micro-controllers programming are addressed with the aim to read correctly signals provided by the interfaced sensors and to drive load such as motors / actuators. Finally, the realization and testing of realized prototypes during course are performed. In addition a comparison of features and performance between Arduino prototyping board and the Raspberry PI 3 platform,  is carried out, in order to be able to choose the most suitable architecture for a specific application, as function of the development board / microcontroller characteristics.
