Ogni modulo equivale a 3 crediti ECTS. È possibile scegliere un totale di 10 moduli/30 ECTS nelle seguenti categorie:
- 12-15 crediti ECTS in moduli tecnico-scientifici (TSM)
I moduli TSM trasmettono competenze tecniche specifiche del profilo e si integrano ai moduli di approfondimento decentralizzati.
- 9-12 crediti ECTS in basi teoriche ampliate (FTP)
I moduli FTP trattano principalmente basi teoriche come la matematica, la fisica, la teoria dell’informazione, la chimica ecc. I moduli ampliano la competenza scientifica dello studente e contribuiscono a creare un importante sinergia tra i concetti astratti e l’applicazione fondamentale per l’innovazione
- 6-9 crediti ECTS in moduli di contesto (CM)
I moduli CM trasmettono competenze supplementari in settori quali gestione delle tecnologie, economia aziendale, comunicazione, gestione dei progetti, diritto dei brevetti, diritto contrattuale ecc.

An embedded system is a specialized computer system with embedded hardware. There exists a wide variety of embedded systems, but in general such systems are processing systems capable of sensing physical inputs from their environment and of communicating the results. Usually embedded systems are designed to perform repeating tasks, either periodically or spontaneously, for low cost, low power, and optimal performance.
In this module, we investigate how microcontroller-based embedded systems can be developed, by emphasizing on the following advantages:
- Provide flexibility with a software-based approach, with the right partition of the system into hardware and software components.
- Provide extensibility of the system.
- Provide easier error detection and debugging capabilities.
- Provide portability with the use of an embedded operating system and allow the programmer to abstract the hardware details of each platform.
- Knowledge of the C programming langage and of an object-oriented language.
- Good knowledge of computer and microprocessor architecture.
- Basic understanding of operating system concepts (scheduling, process/thread).
- Basic concurrent programming
Obiettivi di apprendimento
The students will learn the most important features of a modern RTOS by implementing their own scenario on an IoT development platform that offers a wide range of sensing, processing and communication capabilities. Starting from a basic super loop/bare metal implementation, the students will rapidly reach the limitations of this implementation. These limitations will be studied and improved solutions using scheduling, threading and synchronization will be put in place by the students for the development of a robust, portable and easily maintainable software. In addition, the students will also:
- Implement methods for analyzing the CPU and memory usage of the system.
- Develop methods for automated testing including unit tests and integration tests, toward CI/CD of embedded systems.
At the end of the module, the students will be able to:
- Develop a multi-tasking application on a microcontroller-based embedded system, using a RTOS
- Use the debugging capabilities and build the test environment for an embedded application.
- Understand the memory organization and usage of their application.
- Develop a framework for updating embedded applications, including a bootloader application.
