| Abstract: | The system uses the HT46F49E single chip microcomputer of Holtek company as control unit, using the keyboard matrix and LED array as input and output devices, which introduces a way that uses single-chip input values or internal value after operation to carry out the results and output the corresponding LED on the keyboard light show, and transforms a voice form into corresponding digital. The system can be used for four operations and viewing and enrolling in calendar, time, week. It has the advantages of novel structure, novel, simple structure, avoiding LED display screen defects of traditional display parameter especially suitable for the blind, elderly people. |
