Σύνοψη

The objective of this project is to develop an interface which will allow one way communication between a Personal Computer Keyboard and a microcontroller which uses a Z-80 microprocessor.
The first step of the work was to create a program for the existing MPF-1P microcontroller which allowed the recognission of signals sent by a personal computer keyboard to the microprocessor. This process facilitated the programming of the Z-80 microprocessor to establish the communication with the keyboard.
The Liquid Crystal Display connected to the Z-80 microprocessor provides solid confirmation that the transmitted from the keyboard information is received correctly by the microprocessor.
The whole process of the work revealed the following conclusions:
(a) It is quite important to recognize all information concerning the transmitter and receiver in order to create a communication interface.
(b) The confirmation that the receiver received the transmitted information without errors is an
important issue when a communication link has to be established.
(c) The stage of developing the hardware revealed the difficulties of materializing the theory of
electronics.
