七、 虚拟信号采集分析器 1）：利用信号发生器产生不同信号（信号的相关参数可调） 2）：在信号上叠加白噪声。 3）：对上述信号进行采样（采样频率可调） 4）：在采样的过程中利用均值滤波（每三个点取均值） 5）：显示采样后的波形，并对其进行频率分析。 6）：将采样后的波形与原波形做比较（在同一坐标系中显示） (Seven, the virtual signal acquisition Analyzer 1): different signals generated by the signal generator (signal correlation parameters adjustable) 2): white noise superimposed on the signal. 3): the said signal is sampled (sampling frequency adjustable) 4): In the process of sampling using the mean filter (averaging three points each) 5): Show the sampled waveform and its frequency analysis. 6): the sampled waveform is compared with the original waveform (shown in the same coordinate system))

说明：  微机原理中学到的，依据CPU原理实现的简易CPU系统。(A KIND OF CPU SYSTEM.MADE BY TSINGHUA UNIVERSITY ELECTRONIC ENGINEERING.)

底层调用了PCSC的通信库Winscard，可用于PC上读卡器与智能卡的通信(It calls the underlying communication library Winscard PC can be used on a PC to communicate with the smart card reader)

Including SDKDDKVer.h defines the highest available Windows platform.

说明：  STM32 POS机底层驱动程序，包含打印机驱动程序，SPI FLASH驱动程序，RC522驱动程序 ，PASM卡（7816）驱动程序，磁条卡驱动程序，ILI932X液晶模块驱动程序，键盘驱动程序等(STM32 POS bottom driver, including printer driver, SPI FLASH driver, RC522 driver, PASM card (7816) driver, magnetic stripe card driver, ILI932X LCD module driver, keyboard driver, etc.)

msp430单片机的入门者，可以看看，会有一些帮助。(msp430 microcontroller beginners, you can see, there will be some help.)

该文档详细描述了怎么去离线搭建ceedling环境(The document decribred how to build a ceedling test environment detailde)

HMC5883L测试程序，MCU为AT89S52，经测试可用(HMC5883L testing procedures, MCU for AT89S52, have been tested)

PSCAD软件对STATCOM（静止同步无功补偿器）建模仿真例程(PSCAD software STATCOM (Static Synchronous Var Compensator) modeling and simulation routines)

该程序是本人用AVR ATtiny13写的的一个只用4个IO口驱动两相四线制步进电机的程序，还可以控制转动的上下限（祥见程序屏蔽部分）对使用两相四线步进电机的初学者来说无疑是一笔珍贵的学习资源，对要求以最低成本驱动两相四线步进电机的使用者来说，更是提供了一个有利的参考。推荐！(I use the program is written in AVR ATtiny13 a four IO only I drive two-phase four-wire stepper motor program, but also can control the rotation of the upper and lower limits (祥见shielding part of the procedure) on the use of two-phase four-step beginners into the motor is undoubtedly a valuable learning resource for the lowest cost drive requires two-phase four-wire stepper motor users are provided a favorable reference.
