4、E12864，温度元件为DS18B20，还有一个声音播放器SOUNDER。对于LCD和DS18B20 要进行初始化。将本次设计分成5个模块分别进行设计，分成：温度模块 、LCD显示模块、时间模块、声音模块、调节模块。分模块设计好了以后，再综合起来设计主程序main()，实现所需要求。（2）分模块设计：1.LCD显示模块设计：该模块包括的函数为LCD_inti()/LCD 的初始化、 checkbusy()/检查LCD是否忙碌、 writecode() /写命令、 writedata() /写数据、 hanzi()/显示汉字、 zifu()/显示数字或字符。2.温度模块设计：该模块的函数为int

5、i()/DS18B20的初始化、 readchar()/读一个字节、writechar()/写入一个字节、readtemp()/读取温度 、worktemp()/温度计算。3.时间模块设计：本次是采用T0中断的工作方式1获取时间的。其函数为void timer() interrupt 1 /T0中断函数 、workhour()/时间计算。4.声音模块设计：该模块比较简单，其函数为void s_fmq()/蜂鸣器叫 、nling()/判断是否闹铃。5.调节模块设计：该模块要实现5个模式的调节和转变。模式0：正常工作状态； 模式1：修改时间；模式2：选择一个需要改变的闹铃；模式3：修改选定的闹铃的
