s应广和si470x收音模块功能代码，还有lcd显示(S wide and si470x radio module function code, and LCD display )

A fingerprint matching software which can use to match two fingerprint images and tell the matching percentage.

说明：  舵机stm51控制 实现舵机转动使用，左右摇头(Steering engine stm51 control Realize the use of steering gear and shake head from left to right)

STM32 DAC输出任意波形，可以是正弦波、锯齿波、方波(STM32 DAC arbitrary waveform output)

基于STM32F103单片机的PWM测试源码(PWM test source code based on STM32F103 MCU)

说明：  stm32FOC电机控制程序，使用FOC2.0的库，通过配置后可用于无刷直流电机、永磁同步电机矢量控制(STm32FOC motor control program, using FOC2.0 library, can be used for brushless DC motor, permanent magnet synchronous motor vector control after configuration.)

STM32 模拟的U盘包含两个盘符，一个是SPI读取TF卡，另一个是36K片上Flash，挂载了Fatfs(STM32 USB2.0 massstorage example)

物联网系统的stm32开发代码，包含一氧化碳，温湿度(Internet of Things System)

说明：  本实验将实现如下功能：开机的时候先检测SD卡和SPI FLASH是否存在，如果存在则获取其容量，并显示在LCD上面（如果不存在，则报错）。之后开始USB配置，在配置成功之后就可以在电脑上发现两个可移动磁盘。我们用DS1来指示USB正在读写，并在液晶上显示出来，同样，我们还是用DS0来指示程序正在运行。(This experiment will achieve the following functions: when booting, first detect the existence of SD card and SPI FLASH, and if there is, obtain its capacity, and display it on the LCD (if not, report an error). Then the USB configuration is started, and after the configuration is successful, two removable disks can be found on the computer. We use DS1 to indicate that the USB is reading and writing, and display it on the LCD. Similarly, we use DS0 to indicate that the program is running.)

说明：  实现STM32F4的USBhost功能，使用uvc协议与USB摄像头通讯。(Realize the USB host function of STM32F4 and communicate with USB camera using UVC protocol.)
