The Subsidiary Formative Activity we propose will provide the students with an overall knowledge of embedded systems.
This course willl give basic and advanced notions about software development and hardware design for real-time systems, sensors networks and IoT. Throughout this course different embedded architectures will be introduced along with the most common operating systems employed in this sector. Furthermore, the principal sensors and actuators interfaces will be studied after a revision of C and system programming.
The class will consist of both theoretical and laboratory lectures.
A final project will be assigned to each student, who will be asked to put into practice what he/she learnt during the course.

In collaboration with WSense (http://www.wsense.it) and with the support/help of the Prof. Chiara Petrioli and ST Microelectronics (http://www.st.com).

Syllabus (Under Construction):

1. What is the IoT
2. Wireless Communication (802.15.4/Zigbee, WiFi, Bluetooth, SigFox, LoRa)
3. C in a nutshel
4. Hardware Platforms: Arduino, ST Microelectronics NUCLEO boards, ALEXA
5. HW communication: SPI, I2C, RS232, GPIO & Sensors
6. Energy Power Management
7. FreeRTOS
8. Web Communication & Cloud platforms for the IoT
9. Real Life Examples: Safe Art, Internet of Underwater Things and other projects

You can download the STM32F4 HAL guide from: http://www.st.com/content/ccc/resource/technical/document/user_manual/2f/71/ba/b8/75/54/47/cf/DM00105879.pdf/files/DM00105879.pdf/jcr:content/translations/en.DM00105879.pdf

Final Exam:

Final project + Class presentation.

Deadlines:

By the 23th April you have to submit your group details and the hardware you need.

By the 7th May you have to choose your final project.

By the 4th June you have to upload your project on GitHub. The presentation will be on the 11th June.

Another session can be scheduled.

Hardware available:

3x Bluetooth Low Energy (X-NUCLEO-IDB05A1, Arduino UNO R3 Connector)

1x Uart to Bluetooth

2x Uart to Serial

The verbalization responsible - prof. Anna Labella - will open a Infostud exam. Students have to present the final project. Once evaluated by the teacher, the grade will be communicated to prof. Labella, who shall record the exam result.
