画5阶的贝塞尔曲线,与windows的贝塞尔曲线屏保差不多(painting five bands Bessel curve, and the windows of almost Bessel curve Screen Saving)

单点定位就是根据一台接收机的观测数据来确定接收机位置的方式，它只能采用伪距观测量，可用于车船等的概略导航定位。(Single point positioning is based on observations of a receiver to determine the position of the receiver way, it only can use the false distance measurements, can be used to approximate the travel and other navigation and positioning)

一种利用硬盘序列号对自开发软件的简单且有效的加密注册方法，适用于发布量不大、尤其不公开发行的专用工程软件。主要目的：为使开发者的软件不被任意复制使用，用户每装一台机器都需要向开发者报知用户号并索取注册号。基本原理：将硬盘序列号做运算后做为用户号，开发者可利用科学型计算器，根据用户报知的用户号和只有自己知道的密钥直接算出注册码返回给用户；用户端不需注册机，开发者也不需解码器，且注册成功后Windows系统会自动保存，以后无需再注册，软件升级也无需重新注册。 所附VC源代码中有实现方法和详细注释。(A use of hard disk serial number from the development of software for simple and efficient encryption registration method is not applicable to the amount released, especially not publicly released a dedicated engineering software. The main purpose: to enable software developers to use not to be arbitrarily copied, each user needs to install a machine to developers informing the user number and request a registration number. Rationale: The hard disk serial number as user numbers do after the operation, developers can take advantage of the scientific calculator, directly calculated by the license is returned to the user based on the user notification of user numbers and only you know the key client without RI, developers also need a decoder, and after successful registration Windows system will automatically save the future without re-registration, software upgrades without having to re-register. There annexed VC source code implementation and detailed notes.)

文件夹给出了五个基本的dsp运行程序，基于DSP28335开发板，在CCS编程环境下给出了包括跑马灯、CPU时钟控制程序等五个完整的CCS工程文件。方便初学者学习芯片及编程语言。(The folder gives five basic DSP running programs. Based on the development board of DSP28335, five complete CCS engineering documents including horse-running lamp, CPU clock control program and so on are given in CCS programming environment. It is convenient for beginners to learn chips and programming languages.)

说明：  利用vc6.0提供的支持实现一个ActiveX文档服务器程序。这个程序可以从包容器中装入文件，可以编辑和保存文本以及嵌入对象，它还能够从Internet下载文本文件，每次一行。(vc6.0 use of the support provided to achieve an ActiveX file server. This procedure can pack containers loaded document, and can edit the text and to preserve embedded object, it can be downloaded from the Internet text files, one line at a time.)
