Subject type: Mandatory

Coordinator: Julián Horrillo Tello

Trimester: Third term

Credits: 4

Subject framed in the subject of Industrial Informatics. The course aims to train students in systems design embedded industrial based on 32-bit microcontrollers, and with the support of a real-time operating system (RTOS). Given the characteristics of the industrial environment, real-time reactive systems are studied and designed, implementing mainly control functions, and the appropriate communication systems for the connection of all the elements involved. The basic knowledge on the main elements of the computer systems of the industrial plant is given, emphasizing some key aspects related to thesmartfactory.

This subject has methodological and digital resources to make possible its continuity in non-contact mode in the case of being necessary for reasons related to the Covid-19. In this way, the achievement of the same knowledge and skills that are specified in this teaching plan will be ensured.

The Tecnocampus will make available to teachers and students the digital tools needed to carry out the course, as well as guides and recommendations that facilitate adaptation to the non-contact mode.

At the end of the course the student must be able to:

• LO1: Implement hardware using discrete (SSI, MSI), programmable (PLD) digital components. microprocessors, microcontrollers and DSP (CE28).
• LO2: Design algorithms and write code in high and low level languages ​​(CE28).
• LO5: Integrate applications with various automated systems (CE28).
• LO6: Manage real-time operating systems (RTO) (CE28).
• LO7: Use the scientific-technical terminology of digital electronic components in English (CE28).
• LO8: Prepare technical project reports, evaluate alternatives and justify their analyzes and design criteria (CE28).

The subject alternates weeks with 2 hours and 4 hours of face-to-face classes in the classroom (large group), where the theoretical contents will be developed and practical exercises and problems will be solved, in addition to 2 fortnightly hours dedicated to laboratory practices. and case studies (small group), where the practical part of the first two activities of the subject is worked, and it is deepened in the resolution of exercises and problems. Attendance at all sessions, both theoretical and practical, is mandatory.

The laboratory sessions (small group) are of compulsory attendance (necessary condition to concur to the evaluation of the corresponding activity), and will develop gathering the students in groups of 2 to 6 people. Each activity needs a previous preparation that will be realized, a part in the face-to-face classes in the classroom, and another one will have to realize the students in the time of independent learning. These activities, however, will be temporarily extended beyond laboratory hours, and students will need to complete them during the autonomous learning time.

Whenever deemed appropriate, totally optional activities will be made available to students to help them prepare and prepare for the compulsory ones.

Given the situation caused by the pandemic of COVID-19, the teaching of the subject is done in a hybrid mode: the theory is virtualized and will be done through the use of the ZOOM platform; laboratory practices are maintained in a face-to-face format. The synchronization of teaching has been maintained at all times, while programming the theory sessions in the time slots assigned to the subject.

Thus, weeks have been alternated with 2 hours and 4 hours of class with the whole group through sessions with ZOOM. In these sessions the theoretical contents of the subject have been worked and exercises and problems of a practical nature have been solved.

The 2 fortnightly hours of laboratory practices, taught in person, have been maintained. These sessions work on aspects related to the practical activities of the subject, which consist of the development of software applications for the Cortex M4 MCU, and also work on the topic of computer hardware design. embedded. Work teams of between 2 and 6 people have been maintained, depending on the activity to be carried out.

Attendance at ZOOM sessions, on theory content, and on face-to-face practice sessions is mandatory.

For each activity, teachers will report on the particular rules and conditions that govern them. This information will be communicated in the physical classroom and / or published in the virtual classroom.

One-on-one activities presuppose the student's commitment to carry them out individually. All activities in which the student does not fulfill this commitment regardless of their role (origin or destination) will be considered suspended.

Likewise, the activities to be carried out in groups presuppose the commitment on the part of the students who make it up to carry them out within the group. All activities in which the group has not respected this commitment regardless of its role (origin or destination) will be considered suspended. The responsibility for the results of the work lies with the group, and not with the individuals who make it up. In any case, teachers can, based on the information they have, customize the grade for each member of the group.

Any undelivered activity will be considered scored with zero points. Failure to attend a laboratory session automatically excludes from the evaluation of the corresponding activity, being considered scored with zero points.

It is optional for teachers to accept or not deliveries outside the deadlines indicated. In the event that these late deliveries are accepted, it is up to the teacher to decide whether to apply a penalty and the amount thereof.

The final grade is the weighted sum of the grades of the activities

Activity 1: 10%

Activity 2: 20%

Activity 3: 3%

Activity 4: 3%

Activity 5: 4%

Activity 6: 30%

Activity 7: 30%

Attendance at the theoretical and laboratory sessions and the delivery of the corresponding reports of activities 1 and 2 is a necessary condition for the evaluation of the subject. The algorithm for calculating the grade is only applied if the weighted average grade of Activities 3 and 4 is greater than or equal to 3. Otherwise the subject is suspended.

The resit exam only gives the option to pass the subject with a grade of 5, except in the case where the weighted average grade of the first 2 activities is equal to or greater than 8. In this case the final grade will correspond to the weighted average mark of all the activities of the subject (the resit exam corresponds to activities 3 and 4, and its mark must be greater than or equal to 3).

For activities 1 and 2, if the result of their evaluation is not satisfactory, or the teachers consider it opportune, they will be able to summon the members of a group to carry out an individualized evaluation test.
