本项目是基于Cortex-M3 的地沟油快速检测装置，旨在实现“地沟油”快速，现场检测。MCU控制可编程的直接数字频率合成器（DDS）产生正弦激励信号，经过可变增益放大器（VGA）和低通滤波器（LPF）作用于食用油阻抗传感器（实验室制作）信号经过仪器放大器送入微控制器（MCU）的模数转化（ADC）通道，MCU对采集的信号通过快速傅里叶变换（DFT）处理，实现食用油阻抗与相角的检测；USB和以太网接口，可与计算机通讯，以便对采集的数据进行存储和分析。(The project is based on the Cortex-M3 waste oil rapid detection device designed to achieve " waste oil" rapid, on-site testing. MCU control programmable direct digital frequency synthesizer (DDS) generates sinusoidal excitation signal through a variable gain amplifier (VGA) and a low-pass filter (LPF) acting on the oil-impedance sensor (lab produced) to send signals through the instrumentation amplifier into the microcontroller (MCU) modulo conversion (ADC) channels, MCU signal acquisition via Fast Fourier Transform (DFT) processing, oil resistance and phase angle detection USB and Ethernet interfaces, and computer communication, in order to collect data for storage and analysis.)

基于zigbee技术CC2530 开发控制步进电机(Development and Control of Stepping Motor Based on Zigbee Technology CC2530)

考虑磁场饱和效应的电励磁同步电机矢量控制的一篇论文，在电机考虑磁路饱和是挺有启发的(Electrically Excited Synchronous Motor Vector Control Considering Saturation Effect)

基于STM32F103ZET6的步进电机驱动器A4988的电机驱动测试程序(A4988 driver test code)

RTX实时操作系统是应用于小型嵌入式多任务准并行操作系统实时性高系统性能好(RTX real-time operating system is applied to a small embedded multi task quasi parallel operating system with high real-time performance and good performance.)

单片机虚拟串口仿真图，里面有虚拟串口软件和串口调试助手，还有用proteus进行的仿真图，不用开发板一样进行仿真，只能说proteus太强大了。只要你想不到的，没有他做不到的！(Virtual serial port emulation chip chart, which has a virtual serial port software and serial debugging assistant, as well as performed with proteus simulation map, not the same simulation development board can only say proteus too strong. As long as you think, no he can not do!)

This is an STM32 program for the CS43L22 Audio Codec.

传统的数据采集仪器（如示波器、频谱仪等）尽管采集速率大，但往往功能单一，且造价昂贵，不适合用于多通道、低速率的场合。使用LabVIEW编写的虚拟仪器，功能强大且易于开发，能方便地实现数据实时显示和保存。(Traditional data collection instruments (such as an oscilloscope, spectrum analyzer, etc.) even though a large collection rate, but often single function, and expensive, not suitable for multi-channel, low-rate occasions. Written in LabVIEW virtual instrument to use, powerful and easy to develop, easy to implement real-time data display and preservation.)

说明：  基于labview和NI的采集卡实现信号的连续采集，可自己选择物理通道，并设置采样率等(Based on the acquisition card labview and NI realize the continuous collection, can signal physical channel, and their choice set sampling rate, etc)
