这是NI的LabWindows/CVI虚拟仪器的开发实例，是学习LabWindows/CVI的好帮手(This is the NI LabWindows/CVI development instance of the virtual instrument, is learning LabWindows/CVI is a good helper)

C# Aidy.XmlManager XML的操作类，用来调用XML，读写保存XML文件，十分方便，两个构造函数中，一个是XML文件路径，一个文件路径加上节点路径，在重载的函数中有的需要设置节点路径，方法为：xmlManager.NodePath = "子节点子节点……"所有异常全部抛出，需要在程序捕捉。 　　操作的XML文档路径＝文件路径＋文件全名，XML文档中的节点路径"//根节点/子节点/子节点……" 　　读出指定路径XML文档的全部内容 　　获取XML中节点的内容 　　返回符合指定名称的节点数 　　返回指符合指定名称的节点集中第i个集合的子节点数

这本书延伸科学畅销书“全球定位系统 - 理论与实践”，以涵盖全球导航卫星系统（GNSS），包括俄罗斯GLONASS，欧洲伽利略系统，以及其他系统。书是指在一般意义到GNSS来描述各种现有参考系统的坐标和时间，卫星轨道，卫星信号，可观察，数学模型的定位，数据处理，和数据转换。本书是一本大学级入门教材，目的是作为学生的参考以及为专业人士和科学家在大地测量领域，测量工程，导航和相关学科。(This book extends the scientific bestseller GPS- Theory and Practice to cover Global Navigation Satellite Systems (GNSS) and includes the Russian GLONASS, the European system Galileo, and additional systems. The book refers to GNSS in the generic sense to describe the various existing reference systems for coordinates and time, the satellite orbits, the satellite signals, observables, mathematical models for positioning, data processing, and data transformation. This book is a university-level introductory textbook and is intended to serve as a reference for students as well as for professionals and scientists in the fields of geodesy, surveying engineering, navigation, and related disciplines.)

说明：  STC8F2K64S2系列单片机提供16个中断请求源，分别是：外部中断0中断（int0）、定时器0中断（timer0）、外部中断1中断（int1）、定时器1中断（timer1）、串行端口1中断（uart1）、低压检测中断（lvd）。，串行端口2中断（UART2），串行外围接口中断（SPI），外部中断2中断（INT2），外部中断3中断（INT3），定时器2中断（Timer2），外部中断4中断（INT4），定时器3中断（Timer3），定时器4中断（Timer4），比较器内部PT（CMP），I2C总线中断。除了外部中断2、外部中断3、定时器2中断、定时器3中断、定时器4中断和比较器中断固定是最低优先级中断外，所有其他中断都有四个可设置的中断优先级。(STC8F2K64S2 series single chip microcomputer provides 16 interrupt request sources, which are: external interrupt 0 interrupt (INT0), timer 0 interrupt (Timer0), external interrupt 1 interrupt (INT1), timer 1 interrupt (Timer1), serial port 1 interrupt (UART1), low voltage detection interrupt (LVD), serial port 2 interrupt (UART2), serial peripheral interface interrupt (SPI), external interrupt 2 interrupt (INT2), external interrupt 3 interrupt (INT3), Timer 2 interrupt (Timer2), external interrupt 4 interrupt (INT4), timer 3 interrupt (Timer3), timer 4 interrupt (Timer4), comparator interrupt (CMP), I2C bus interrupt. Except that the external interrupt 2, the external interrupt 3, the timer 2 interrupt, the timer 3 interrupt, the timer 4 interrupt and the comparator interrupt fixed are the lowest priority interrupts, all the other interrupts have four interrupt priorities that can be set.)
