语音芯片在电子日历中的应用

摘要

电子日历的设计,主要是利用单片机的串行口实现时间、星期、公历日期和农历日期的显示,还可根据需要通过键盘对时间及公历日期进行设定.为了完善系统,也对利用语音芯片实现报时的功能进行了研究,主要研究了与单片机控制系统的接口电路和外围电路,以及其录放音原理等.%Electronic calendar is based on microcontroller as the core,primary function is to use microcontroller serial interface calendar date,time,Lunar calendars and weeks,could also needed by the keyboard right calendar date and time settings.In order to perfect the system,but also the use of voice chip timekeeping function were studied.And the interface circuit and peripheral circuit of the control system are designed,the recording and playing principles studied.
