STM32 WM8960驱动代码

《c++项目开发全程实录》一书中图书管理系统开发的讲解录像和相应源代码 (something about a book C++ project development: a memoir . books management system management system development and application of video and the interpretation of the source code )

电机驱动，嵌入式应用，很好的资料，我也刚找到。和大家分享(Motor drive, embedded applications, very good information, I have just found. And the U.S. share)

说明：  修改系统寄存器 在UEFI的环境下，，，，，，(Modify System Register)

LED一秒闪烁，蜂鸣器三秒短鸣，六秒长鸣

矩阵按键程序，用的是C。本人还是学生，做得不好请大家多多指教(Matrix button procedure is used in C. I am still a student, doing a lot of bad advice please)

: 针对实际振动位移难以获取的问题, 利用振动位移与加速度信号之间的关系, 先对采样后的加速度信 号采用时域数值积分,得到含有趋势项的速度信号及位移信号,再采用拟合多项式极值的方法, 消除积分过程 中产生的趋势项,从而得到更为精确的速度和位移信号. 算例表明, 利用拟合多项式极值消除趋势项的方法, 得到的位移时程曲线拟合精度高(: In pract ical engineering , the collection of displacement data is mo re dif ficult than that of the acceleratio n data in the time-domain .Displacement sig nals w as g ot f rom acceleration s ignals using aumerical integrat ion , wi th the t rend o f erro r.
