Course detail

Microprocessor Technics for Drives

FEKT-BKC-MTPAcad. year: 2023/2024

The course familiarizes students with applications of microprocessors used for measurements and process control. They are expected to have basic knowledge of digital circuits and elementary level of English. The students will widen their knowledge of digital circuits and their use. They will work individually with development systems for the Freescale DSP56F800E microprocessors, develop programs in the C language and uses measurement instrumentation for microprocessor circuits analysis. The course is focused on applications of the one-chip microcontrollers, measurement of electric and nonelectric quantities and digital control.
