基于51单片机控制的语音报时万年历课程设计1

1、基于51单片机控制的语音报时万年历-20/11/2013 sdu(wh)1 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2 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

2、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
