基于51单片机控制的语音报时万年历

基于51单片机控制的语音报时万年历

-----20/11/2013 SDU(WH)

一．实验要求

运用单片机及相关外设实现以下功能：

1）万年历及时钟显示

2）时间日期可调

3）可对时间进行整点报时和随机报时

二．方案分析

根据实验要求，选用STC公司的8051系列，STC12C5A16S2增强型51单片机。此单片机功能强大，具有片内EEPROM、1T分频系数、片内ADC转换器等较为实用功能，故选用此款。

实验中，对日期和时间进行显示，显示的字符数较多，故选用12864LCD屏幕。该屏幕操作较为便捷，外围电路相对简单，实用性较强。

为了实现要求中的时间日期可调，故按键是不可缺少的，所以使用了较多的按键。一方面，单片机的I/O口较为充足；另一方面，按键较多，选择的余地较大，方便编程控制。

实验中，并未要求对时间和日期进行保存和掉电续运行，所以并未添加EEPROM和DS12C887-RTC芯片。实际上，对万年历来说，这是较为重要的，但为了方便实现和编程的简单，此处并未添加，而是使用单片机的定时器控制时间，精度有差别。且上电默认时间为2014-01-01 09:00:00 之后需要手动调整为正确时间。

要求中的语音报时功能，这里选用ISD1760芯片的模块来帮助实现。此模块通过软件模拟SPI协议控制。先将所需要的声音片段录入芯片的EEPROM区域，之后读出各段声音的地址段，然后在程序中定义出相应地址予以控制播放哪一声音片段。
