Multi-functional Demo Module for Microprocessor Development Systems for Educational Purposes

An approach applying development boards based on various microcontrollers with minimum peripherals is provided in the paper. They are intended for teaching Microprocessor Circuits and Systems. To extend their functions and facilitate students, a universal (multifunctional) demo module has been designed, that contains frequently used peripheral blocks - input/output devices, like buttons, LCD, LEDs, rotary encoder; motor drivers, etc.
