单片机课程设计报告模板Word格式.docx

1、执行部件电路：包括喇叭、状态指示灯。二、方案论证及选择1、电子琴部分由于市场上有许多的电子琴，从而想用单片机来实现电子琴的功能和音乐盒，通过7个按键代替市场上电子琴的按键，最后一个按键用来播放音乐。音乐是由不同的频率所产生的声音，通过控制时间来给喇叭送电平，从而使喇叭发出不同的响声，在通过查找歌曲的音符，做成一个音符表。通过按按键在由程序控制表的取的次序从而让喇叭发播放音乐。通过滑动变阻器控制喇叭声音大小。2、测温部分 测温部分是基于DS18B20温度传感器的探测，然后实时传输给数码显示器。并且设有温度报警系统。当外界温度高于50或者低于-20时状态指示灯亮，蜂鸣器发出警报。3、计数部分 RR

2、0加一，RR1减一，RR2加十，RR减十.第三部分 电路设计与参数选择一、 单片机最小系统电路设计和元件的选择第四部分 软件设计部分一、#include hardware.hintrins.h#define uchar unsigned char#define uint unsigned int uchar TempTH0,TempTL0,bian;/临时的Th0和Tl0 ，修改定时器中断时间用的变量uchar YinFu,JiePai,shu,shu1,TimeSec=10;static uchar temp;uchar code TabMusic7340;bit Flag,ZF;/0:电子
