华为公司的天线应用技术，无线网络规划培训教程，形象讲解天线技术，偏重于讲微波天线...

用C及ftp实现软件自动升级。通过在服务器端建立FTP服务,实现远程主机的文件更新. 软件启动过程连接服务器,获得软件文件更新列表(此步省略),进行本地文件更新 启动过程进行系统调用执行批处理文件ftpget.bat,调用方式system( "e:ftpget.bat" ) 文件ftpget.bat负责连接服务器下载所需文件,并完成文件的更新-C ftp software and automatic upgrades. Through the establishment of FTP server, remote mainframe file updates. Software startup process server connectivity, access to software updates list (this step is optional), a local paper started the process of updating system calls for the implementation of batch file ftpget.bat, call mode system ( "e : ftpget.bat") documents ftpget.bat for connecting servers to download the necessary documents, and complete the document update

 X, Y coordinates points for the graph is generated randomly and put it in a trace file. The trace file is given as input file to xgraph to plot the graph. Here two trace files are plotted in the single graph. Point of each trace file will be differentiated in color.

应用背景这个代码可以利用cc2530的 SPI功能 读取或写入外部FALSH  记得写入前一定要先擦出扇区。关键技术CC2530  无线zigbee芯片 外部扩展FLASH功能 可以兼容大多数FLASH芯片

EEPROM的几种保护方法 .rar EERROM的数据比较容易丢失,用这个方法-EEPROM several protection methods. Rar EERROM data more easily lost, Try using this method

西门子S7200PPI档案 PPI通讯方式通讯协议,适合驱动程序的编写参考-Siemens PPI file S7200PPI communication protocol for the preparation of reference driver

这是一个通讯软件-This is a communications software

ＯＦＤＭ宽带无线系统的链路级的仿真程序（多天线，ＱＡＭ调制，编码，合并）等等很齐全）-OFDM broadband wireless system link-level simulation program (multi-antenna, QAM modulation, coding, combined) and so very full)

就是用串口通讯线将两台机子用串口连起来进行通讯，最简单的。比如在a机上输入一个字符，在b机上能显示出来 -Serial communication is to use two machines will be used for serial communication link, the most simple. For example, in a plane into a character, b plane will display

can总线通信C++ BUILDER源程序。用于编写can通信协议，以及测试can总线。-can BUILDER C bus communication source. Can prepare for the communication protocol and can test bus.
