Course detail

Microprocessor Control

FSI-RTEAcad. year: 2019/2020

Students are acquainted with applications of microcomputer technology in process measurement and control. They will be familiar with the functioning of ARM processors and some peripherals, as well as some algorithms used especially for control of electric drives. Exercise uses relatively easy-to-use development kits and software tools with which listeners work independently and program in C language.

Learning outcomes of the course unit

Practical application of digital technology and single chip microcontrollers in the control of mechatronic processes, programming in C language, independent work with laboratory development system. Orientation in modern microprocessor systems and basics discrete control methods.

Planned learning activities and teaching methods

The subject is taught in the form of lectures, which have the character of interpretation of basic principles and theory of given discipline. The course is complemented by laboratory exercises that are focused on a specific application.

Assesment methods and criteria linked to learning outcomes

In the exercises during the semester, you can get a certain amount of points for activity and two individual tasks. A non-zero evaluation of both tasks is necessary for granting the credit. The final exam is written and may include a microcontroller program development.

Language of instruction

Czech

Work placements

Aims

Acquisition of the theoretical and practical fundamentals of digital technology and microcomputers, introduction to management algorithms.

Specification of controlled education, way of implementation and compensation for absences

Mandatory participation in laboratory exercises (2 absences acceptable). Processing of tasks, possibility of replacement according to individual agreement with the teacher.
