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)

ZB220GDNZ_PSR测控装置的IEC61850配置的icd文件(ZB220GDNZ_PSR of IEC61850)

买的一块开发板的开发文档、原理图还有PCB板，并且附有PCI9054的驱动程序及上位机测试应用程序，调试时需要安装Windriver。(Development board to buy a piece of the development of documents, there are PCB board schematics, and with the PCI9054 PC drivers and test applications, when the need to install debug Windriver.)

使用STM32F4+usb3300实现虚拟示波器,支持使用外部ADC模式，也就是使用AD9280芯片，最大采样率可达30MSPS.(STM32F4+usb3300 implementation of the virtual oscilloscope, support the use of external ADC mode, that is, the use of AD9280 chip, the maximum sampling rate of up to 30MSPS )

此程序是CFD中用户自定义中的定义速度变化的程序，输入到Fluent中控制入口速度(This program is a change of user-defined in the definition of speed in CFD program, the input to control the inlet velocity in Fluent)

模拟键盘击键,比较不错的一个程序.做软件仿真的(Analog keyboard keystrokes, compare a good one. To do software simulation of)

这个程序可以实现两个单片机之间双向通信的功能。(This program can realize the function of two-way communication between two microcontrollers.)

HM20通用型压力变送器 资料很全 值得下载 (HM20 Universal Pressure Transmitter)

说明：  MSP430红外解码驱动，占用了一个定时器资源。(MSP430 IR decoding drive, taking up a timer resources.)

nrf905 接收机程序 89C52 验证通过 绝对好使(nrf905 receiver program 89C52 verified through absolutely so)
