Course detail

Microprocessor Technics for Drives

FEKT-BPC-MTPAcad. year: 2024/2025

Students are introduced to the applications of microcomputer technology in the measurement and control of electric drives. Basic knowledge of digital technology and a basic level of English are assumed. Students will expand their knowledge of digital circuits and their applications. They work independently with development systems for STM32 series microcomputers and program them in C.

Department of Power Electrical and Electronic Engineering (UVEE)

Entry knowledge

A student enrolling in the course should be able to:     - explain the principles of logic circuits and the representation of a logic state using voltage levels     - design algorithms and implement simple programs in any programming language     - have a command of the English language at the level required to study microprocessor manuals and help for the programming tools used       Work in the laboratory is contingent upon a valid "person of instruction" qualification, which students must obtain prior to beginning instruction. Information on this qualification is given in the Dean's Guideline on Student Familiarity with Safety Regulations.

Rules for evaluation and completion of the course

Active participation in laboratory exercises, independent projects and an exam are assessed. The final exam is in the form of a test. The definition of supervised teaching and the method of its implementation are defined in the annually updated decree of the course guarantor. Laboratory teaching is compulsory. 

Aims

Students are introduced to the basics of digital control using single-chip microcomputers and the basics of programming in C. A written examination verifies that the graduate of the course is able to: - Explain the principles of microprocessors at the level required for assembly programming and explain the related concepts: register, memory, program, CPU, program counter, linker, compiler, debugger, interrupt, interrupt handler, interrupt vector, interrupt flag, peripherals, stack, stack pointer, status register, conditional jump, - Explain the principles of peripherals for controlling electric drives with transistor inverters (GPIO, PWM, ADC, Timer, SPI, SCI) - apply the C language in single-chip microprocessor programs Students will learn in laboratory exercises and the ability is verified through assessed individual projects: - use development tools to create and debug microprocessor applications, - implement C language programs for real-time control, - set up and use microprocessor peripherals to measure analogue signals, measure the frequency of pulse signals, generate PWM.
