说明：  在工业控制软件中经常要显示测量数据,如果在在界面上单纯显示一些数字会显得很单调,如果能在软件中添加色泽艳丽的控件,就一定会(Measurement data are often displayed in industrial control software. If you simply display some numbers on the interface, you will be monotonous. If you can add brightly colored controls to the software, you will certainly be able to)

快速傅里叶变换(FFT)算法C++实现代码 (Fast Fourier Transform (FFT) algorithms to achieve C code)

Profibus-DP从站原理图， VPC3芯片配合STM32F103RBT6的系统，AD6原理图格式。(Profibus-DP slave schematics, VPC3 chip with STM32F103RBT6 system, AD6 schematic format.)

串口通讯技术实现--两台pc机通过串口通讯（C语言）并可以调整波特率，奇偶校验位等。 (Serial Communication Technology- two pc machine through serial communication (C language) and can adjust the baud rate, parity bit and so on.)

Modbus协议及Modbus RTU的C51编程(Modbus RTU Modbus protocol and the C51 programming)

本代码主要关于摄影测量中的单向空间后方交会(resection of photogrammetry)

基于PCF8591的51单片机温度监测系统，串行AD转换，程序已验证可行，显示准确，含proteus仿真文件(Based on PCF8591 51 single chip temperature monitoring system, serial AD conversion, the program has been verified feasible, accurate display, including proteus simulation file.)

可以实现HTTP转发/HTTP请求,如果需要做一个网页下载,那么可以使用该类,该类最大的特点是支持PROXY代理下载!(HTTP can be transmitted/HTTP request, if required to do a website, then you can use this kind, the largest such feature is support PROXY proxy to download!)

过于滤波，采用卡尔曼滤波有关的方法。比较简单。打开文件，希望有用(kalman filter)
