Synopsis:

Basic methods of application of microprocessor and single-chip microcontroller in the design of microprocessor controlled measurement instrument are presented in this course. The operation of microprocessors, memories, input/outputs and other hardware blocks and their interfacing is explained. The laboratory exercises are oriented on the individual design and experimental realisation of simple instruments controlled by microprocessor 8051.
