Σύνοψη

This project deals with the design of a system which stores words in his memory and it playbacks them, taken measurements in who many dB we hear them. All these actions are shown on LCD display to the users, who can choose the next action from a keyboard.
The whole system is designed by the aid of a Computer Aided Design (CAD) program. First was designed the recorder circuit and then the μP system with its peripherals (keyboard, alphanumeric display, etc.). The reason that we make first the recorder circuit is for the
complexity ofit and the problem that we have to control it.
Software was written for the operation of the system as required and stored in system's EPROM. An 8051 assembler was used along with an 8051 disassembler, an EPROM
programmer.
The operation of the whole system was tested using Logic Analyzer (disassembler) and
oscilloscope.
The system was fully operating as was designed.
