基于STM32开发板的播放器设计

生产实习报告 基于STM32的播放器设计1 概述（1）使用STM32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。二总体设计框图蜂鸣器液晶显示MCU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。3、 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ARM板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OLED上面。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4 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。5 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。6 关健程序代码 主程序的菜单显示模块：重力感应实现上下曲的代码:时间显示模块的部分代码：七 相关问题：1 重力感应实现的基本原理：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 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 时的输出为 V ，且在1g 加速度作用下的输出为V ，则有： 0 V =V / g sin 1g +V 即： = arcsin(V 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。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.hacc_3d mems;extern u8 DisplayBuff20;int LI35_out(void);extern void beep(void);extern void time_test(void);unsigned char hanzi32=/*- 文字: 欢 -*/*- 宋体12;
