锁相环用于电机转速精准检测，资料很不错，值得下载(Phase-locked loop for accurate detection of motor speed)

实现单片机与LABVIEW的串口通信。单片机部分的上载程序，只需用LABVIEW构建一个简单的输入与输出指令界面(LABVIEW MCU and serial communication. Single-chip part of the upload process, just use LABVIEW build a simple command interface, input and output)

CC2530 步进电机控制实验。一个简单的例程(CC2530 stepping motor control experiment)

一个以太网帧解析程序，实现以下功能：解析已封装好的Ethernet V2.0帧封装文件（见附件），判断有多少个帧，每个帧的所有字段内容，检测CRC校验是否正确(An Ethernet frame analysis program, the following functions: parsing the encapsulated Ethernet V2.0 frame encapsulation (see annex), to determine the number of frames, each frame contents all fields to detect CRC checksum is correct)

超声波测距，能够实现汽车防撞系统超声波的测距，完全由51单片机控制(Ultrasonic Ranging)

读取ssdt函数当前地址，详见源码中、。。。。(Ssdt function reads the current address, see the source code. . . .)

24CXX的读写代码,适用于于51单片机SCM.可直接使用。 (24CXX the read and write code, suitable for 51 MCU the SCM can be used directly.)

直流斩波变化的仿真和一些参考文献 可以学习一下(The simulation of dc chopper change and some references can learn )

基于stm32f407的手写识别程序，亲测可用(Handwriting recognition program based on stm32f407)

1. 本研究利用 PCA 对可见-近红外（450～1 000 nm）、可见光（450～780 nm）和近红外（780～1 000 nm）光谱区域的苹果高光谱图像数据进行降维，获得 PC 图像，通过对 PC 图像进行分析，确定可用于分割损伤和正常区域的有效光谱区域，对比分析几个光谱区域的 PCA 的效果。(but currently no practical system for detecting blood spots and dirt stains exists. In order to obtain maximum throughput, processing speeds of over 85,000 eggs per hour are common. The demanding requirements placed on the human workers result in two types of grading errors)
