Course detail

Microprocessor Control

FSI-RTEAcad. year: 2020/2021

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.
