学习情境1 多功能音乐播放器的设计
江西环境工程职业学院机械与电子学院
一、 引言

二、 设计任务与设计原理
1、 设计任务
（1）可播放多首音乐，且通过按键来选择播放的音乐
（2）选择音乐时，音乐名称在LCD上显示
（3）音乐播放种类跨度要大一些，播放声音要清晰
2、 设计原理

三、 硬件电路设计

四、 软件设计
1、 流程图设计

2、 完整程序代码
整个KEIL工程文件有4个.C文件和1个头文件组成，具体代码如下：
（1）PlayMusic.c
#include <REG52.H>
#include "SoundPlay.h"
#include<math.h>
#define uchar unsigned char
#define uint unsigned int
sbit WAI_INT0=P3^2; // 复位
//水平与垂直偏移
uchar H_Offset=0; //
uchar V_page_Offset=0;
extern uchar Key_Num;
extern uchar code Name_Of_Song[];
extern uchar KeyScan(); // 矩阵键盘扫描子程序
extern void LCD12864_Initialization();
extern void Display_Word(uchar P2,uchar L2,uchar *M) reentrant;
extern void Display_char(uchar P1,uchar L1,uchar *M) reentrant;
void delay(uint K); //延时子程序
void key_process();// 矩阵键盘按键处理子程序
void Delay1ms(uint count)
{
unsigned int i,j;
for(i=0;i<count;i++)
for(j=0;j<120;j++);
}
