(完整版)基于STM32开发板的播放器设计

1、生产实习报告基于STM32勺播放器设计- 概述(1)使用STM3编写代码送至蜂鸣器中，实现简易的播放器功能(2)通过使用时钟芯片，可以显示出当前的时间日期(3)可以通过重力感应完成上下一曲。(4)开机时有开机动画。(5)完成完整的电路设计原理图及软件源代码。二总体设计框图液晶显示MCU蜂鸣器小组分工：总体设计：由组长郑健师完成。时间模块：张春蕾、张宁、张道永。重力感应模块：宗瑞、张正阳、金以俊、司良振。开机动画模块：王丹阳、张金凤、宋加伟。三、关键模块设计1、重力模块设计：在播放音乐时，可以通过改变ARM5的重心来进行歌曲的前一首和后一首的 切换.实现方法：在每次播放音符的时候检测是否有重力偏

2、转的大幅度改变，如果有，则停止播放当前歌曲，进去上下曲的播放。此外软件还设有重力感应锁定模块，只需要将开关 1打上就可以实现2、时间显示：这个模块主要是通过例程实验代码实现的。具体的就是读取时钟芯片的数据，然后显示在OLEDt面。3、开机显示：读取汉字“欢迎光临”程序没执行一次，改变显示的位置，从而实现了文字 在动的效果四.测试结果通过我们这两个星期的努力，我们的任务基本实现了，我们通过蜂鸣器来实现播放，通过重力感应来完成下一曲上一曲的播放和功能选择，还有就是开机动画也完成了预期的效果。五.总结我们经过了两个星期的共同合作，我们从一点也不懂，到对基板有了比较理性的认识，再到完成了基本的设计，实

3、现了基本的功能，团队协作精神也得 到了提高。我们从中收获了很多。六.关健程序代码主程序的菜单显示模块：while (1J打显前受的违乐桌单8rrtf Dhta (Hy_Kflic 0 ,6,16+1,3,11;KritcDota (Hyjnuaic 1 ,17+6,334rlr 3,1);WriteData (My_ni3ic 2 f 34-hfi, 504rlr Sf 11;Wri t eEata Hyjmimic 3 L 51+6+仇 Id L);品示时同菜至wmeDatnHhiKan叫血 16地 1 冉 1):feiteDatafshljian 1 f 17+6,33+4,1 1);Sr

7、本原理：重力传感器是将运动或重力转换为电信号的传感器，主要用于倾斜角、惯性力、 冲击及震动等参数的测量。在测量平台倾斜角时，将重力传感器垂直放置于在所测平 台上，重力传感器的敏感轴应与倾斜平台的轴向一致，在水平状态下应与水平面平行。其中a为平台沿某一方向的倾斜角。重力传感器的质量块由于受到重力加速度g在倾斜方向上的分量g : g = g sin 的作用产生偏移，使重力传感器的输出电 压发生变化。若重力传感器在水平状态下的输出为 0 V，倾角为a时的输出为a V ,且在1g加速度作用下的输出为 V ,则有：0 V =V / g Xsin a x 1g +V a 即：a = arcsin(V a

8、- V0 ) /V 利用上式可以方便求得平面某一方向上的倾斜角。如果将两个重力传感器正交放置在平台中心，则平台在x方向上倾斜角x %和平台在y方向上倾斜角y %为:x arcsinV( x V) /V,arcsin(V V ) /V y y根据这两个方向上的倾斜角可以确定出平台的横向倾角和纵向倾角。图1角度传感器2时间模块是如何实现: 实现原理图八关健程序代码主程序 main： #include include.h#include uart.h#include stm32f10x_spi.h#include OLED.h#include MEMS.h#include #include TWI.
