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。3 电路硬件设计实际效果图4 程序代码部分Main.h#ifndef _MAIN_H#define _MAIN_H#include reg52.h#include INTRINS.H#include math.h#include string.h#include key.h#include led.h#include 12864.h#include main.h#include isd1700.h#include sound.hextern unsigned int count;extern unsigned int key_time8;extern unsigned char key_new;extern unsigned char key_old;extern unsigned char stop_flag;extern unsigned char key_follow8;extern unsigned int key_num8;sbit BEEP=P37;sbit ISD_SS=P07;sbit ISD_MISO=P04;sbit ISD_MOSI=P05;sbit ISD_SCLK=P06;extern unsigned char date_show;extern unsigned char time_show;extern unsigned char sec;extern unsigned char min;extern unsigned char hour;extern unsigned char day;extern unsigned char month;extern unsigned char year_f;extern unsigned char year_l;extern unsigned char leap_year_flag;extern unsigned char update_flag;extern unsigned char adjust_flag;extern unsigned char key;unsigned char report();#endifMain.c#include main.hunsigned int count=0;unsigned int key_num8=0;unsigned char key_new=0;unsigned char key_old=0;unsigned char stop_flag=0;unsigned char key_follow8=0;unsigned char sec=1;unsigned char min=0;unsigned char hour=9;unsigned char day=1;unsigned char month=1;unsigned char year_f=20;unsigned char year_l=14;unsigned char leap_year_flag=0;unsigned char date_show=2014-01-01;unsigned char time_show=09:00:00;unsigned char update_flag=1;unsigned char key=0;unsigned char adjust_flag=0;unsigned char adjust_pos=0;unsigned char report_flag=0;void main()unsigned char i;P2=0XFF;BEEP=0;init();initinal();
