Design of electronic clock with speech broadcast
Abstract: The design of speech tick electronic clock,base on chip microcomputer AT89S52, is composed by the following functional modules: keyboard displaying ,sound phonating.，temperature gathering ,LCD display.The microcomputer get time data from time chip DS1302,then data processing and the output is displayed on a Chinese character LCD 12864,and process time get across the keystroke. According to the basic requirements of the subject ,our system stresses on the realization of time displaying and sound timing, througth the speech chip ISD4004 record the sound, the microcomputer get the time data and take out the data from the speech chip, sound timing.Furthermore ,we also extend the primary function ,adding new functions ,such as the single chip peripheral ports ,temperature gathering , sound timing and so on..
Key words: sound timing ; chip microcomputer ；Chinese character LCD；time chip
