Applications of Microprocessors in Measurement

The course is a substitute for:

Applications of Microprocessors in Measurement (E38MIP)
Programming of Single Chip Microcomputers and Microcontrollers (X38MIP)

Lecturer:

Tutor:

Supervisor:

Department of Measurement

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.

Requirements:

Students should feel comfortable programming and using computers. A basic

knowledge of logic design and circuit theory is assumed. Additional

circuit-level and architecture-level knowledge would be useful but is not

essential.
