人脸识别（PCA）

说明：  APC强杀进程，内核开发，可以杀死大部分安全软件。(APC strong kill the process, kernel development, can kill most of the security software.)

说明：  这是Blowfish算法实例 VC++实现的(This is the Blowfish algorithm examples of the VC)

ECG C程序，亲测能用。主要计算心率，HRV，VC程序，内有滤波等函数

此程序和上一个程序是用于51单片机和430单片机的通信，通信方式为单工，430做主机51做从机(This program and a program for 51 And 430 single-chip communication, means of communication for the simplex, 430 to do Host 51 to do slave)

基于stm32的jy901oled显示测量角度(A jy901oled display measurement Angle based on stm32)

用于全桥逆变电路的移相软启控制程序，周期和启动时间均可调节。(Phase-shifting soft-start control program for full-bridge inverters has adjustable cycle and start-up time.)

使用STM32官方提供的DSP库进行FFT，虽然在使用上有些不灵活（因为它是基4的FFT，所以FFT的点数必须是4^n），但其执行效率确实非常高效，看图1所示的FFT运算效率测试数据便可见一斑。该数据来自STM32 DSP库使用文档(. Using the official DSP library provided by STM32 for FFT is not flexible in use (because it is the FFT of base 4, so the number of FFT points must be 4 ^ n), but its execution efficiency is really very efficient, as can be seen from the test data of FFT operation efficiency shown in Figure 1. This data comes from STM32 DSP library usage document)
